How to install drivers after reinstalling windows 7. Audio and video players
Use everyone modern versions Windows is pretty simple. But you need to understand that any OS is a very complex system in itself, so there are various kinds of problems after Windows installations 7 occur from time to time for any user. It is often very difficult to solve them without having really extensive experience in operating and configuring this system. Therefore, we will tell you below how to eliminate some problems that arise after its installation and directly during operation.
After installation, Windows 7 cannot detect the second drive
During the system installation process, the latter reserves a hidden System Reserved system partition on the disk. It is used to boot files The OS was protected after installing Windows 7. Sometimes, if the system is installed on a computer with two physical hard drives, Windows 7 can detect second HDD incorrect and use it just as a hidden System section Reserved. As a result, it will not have a drive letter.
For the system to detect the second hard drive after installation:
If after this you still do not find your second disk in Explorer, then simply restart the PC, after which the problems incorrect installation will be decided, and he will definitely appear.
The computer cannot determine the local drive on which the previous installed OS is located, or the letter of this drive is not displayed
By performing the above steps, installation problems with definition local disks in Windows 7 will be resolved.
Windows Installer fails to install, uninstall, or update applications
reg delete HKLM\SOFTWARE\Microsoft\SQMClient\Windows\DisabledSessions /va /f
Windows 7 x64 displays less memory than it actually has
If this measure does not help solve the problem, go to BIOS settings and change the settings. Try to find the HPET Mode function.
If it exists, then its value must correspond to 64-bit . If there is none, then look for either the Memory Remap Feature line - the value should be Enabled, or Memory Hole - Disabled. Otherwise, the system will not “see” more than 3-3.5 GB of memory.
After rebooting, Windows freezes and an error appears: Verifying DMI Pool Data
In this case they can help the following actions to solve the problem:
- Resetting CMOS to motherboard- or click on system board the corresponding reset button, or reinstall and return the jumper;
- If several are installed hard drives, then in the list BIOS downloads set priority to the drive on which Windows is installed;
- Connect the disk that was allocated for installing Windows 7 as Primary Master.
If the described steps do not help, reset the BIOS settings to standard and reinstall the system. 
The above described ways to eliminate only a small portion of the problems that may appear after installing Windows 7. Many errors can be caused by the lack of necessary drivers in the system or their incompatibility with this OS, so try to install only the latest versions downloaded from official sources.
Collateral successful work only installed Windows 7 is hers correct setting before use. You can see how to perform this setup here:
The problem when the Internet does not work after reinstalling Windows can arise not only in Windows 7, but also in Windows 8 and Windows 10. I will later try to prepare a separate article about solving this problem on the “top ten”. Besides, I already wrote. Just follow a few tips from the article, and the Internet on your computer will work again.
And in this article, we will look at solutions to the problem when you (or someone else) installed on your computer, or Windows laptop 7, everything worked out and everything works, but there is no Internet connection. There can be a lot of different nuances. Because there are many ways to connect to the internet. Therefore, the solutions will also be different. Looking ahead, I’ll say that most likely you just need to install necessary drivers, or set up an Internet connection (or both). Because, immediately after installation, Windows 7 almost never installs a driver for the Wi-Fi adapter. This means that Wi-Fi will not work after installing Windows 7. Well, if you had an Internet connection configured, then of course you need to configure it again.
It all depends on the connection method, and in some cases on the Internet provider. We will consider the following options:
- Wi-Fi does not work after installing Windows. In almost all cases, simply installing the wireless adapter driver is enough. Windows 10 already installs the driver for Wi-Fi (In most cases), but Windows 7 lags behind in this regard.
- If the Internet does not work via cable from the router. Again, it all depends on the symptom. It may also be that the system was unable to install the network card driver. You need to check and, if necessary, install it.
- If you previously configured a connection to your provider (high speed), but after reinstalling Windows 7 it is not there. It's quite normal. It is advisable to first check if there are any problems with the network card driver, then simply create a connection to the provider.
- And if you have Internet via a 3G USB modem, then you must install the modem driver, and again, set up a connection to the provider.
Now we will look into everything in more detail and solve problems with connecting to the Internet after installation or reinstallation operating system.
Why doesn't Wi-Fi work after installing Windows 7?
And so, we installed Windows, we look at the Internet connection icon, but it is not the same as it was before. No available for Wi-Fi connections networks, and we cannot connect to the Internet via Wi-Fi. Most likely, the connection status will be like this (if the network cable is not connected):
The fact is that there is no Wi-Fi at all. No available networks, and most likely you won't even see the wireless adapter. And all because Windows 7 simply could not install the driver on the wireless adapter that is installed in your laptop, and which is responsible for Wi-Fi work. How many times have I reinstalled Windows 7 on different laptops, and the Wireless adapter driver always had to be installed manually.
It's very easy to check. Just go to the device manager and take a look. You can open it different ways. The simplest one: open Start, paste it into the search bar mmc devmgmt.msc, press Enter. Or via "Run". You can also go through “Computer” - “Properties” - “Device Manager”.
In the manager we look for the tab Network adapters. And there should be an adapter with “Wireless” or “Wi-Fi” in its name. Like this:
If you do not have such an adapter, or you do have one, but with a yellow one exclamation mark and the status “The device is not working correctly”, this means that you just need to install the necessary driver, and everything will work. In this case, in the device manager there must be at least one " unknown device". This is our Wireless adapter.
The main thing is to install the driver for your laptop model (adapter), and for Windows 7 (in our case). I won't write about this in detail here. Has already detailed instructions About, . After installation, you will be able to networks.
Internet via cable does not work after reinstalling Windows 7
If you have an Internet connection via network cable from the router, or directly from the Internet provider, but without any settings, when there is no need to create a connection, then first of all we check the network card driver. It also happens that Windows 7 cannot install it either. This is the case when the computer does not respond to cable connection (the icon does not change). And if he sees the connection, but it is “Without access to the Internet,” then look. But this is unlikely.
And so, go to the device manager (how to log in, I wrote above), and on the same tab "Network adapters" we should have LAN card. I have this "Realtek PCIe GBE Family Controller". Your name may be different. It all depends on the manufacturer.
If you do not see a network card adapter there, then as is the case with wireless adapter, you need to install the driver. If you have a laptop, then look for the model on the manufacturer’s website and install the driver for the LAN adapter. You can search by the name of the adapter itself. Also, the driver is on the disk that may have come with your computer.
Well, check all the cables, maybe you are connecting something incorrectly.
Lost high-speed connection to ISP on laptop after reinstalling Windows 7
In this case, you just need to create this connection again. Connect the cable from your provider to your computer's network card (it's most likely already connected). If your computer does not respond to the cable, or you are unable to create high speed connection, then check if everything is ok with the network card driver. I wrote about this above.
To create a connection to your provider, click on the Internet connection icon and select "Network and Sharing Center" shared access". Next, click on "Set up a new connection or network."
Select "Connect to the Internet" and click "Next".
Select "High Speed (with PPPoE)".
Enter the username, password, if desired, check the “Remember this password” checkbox, you can change the name of the connection, and click on the “Connect” button.
Connection information: username and password, issued by the provider. If you also need to register IP and DNS addresses, you can do this using , in the properties of the adapter “Local Area Network Connection”.
Internet does not work via 3G USB modem after installing Windows
As with other connections, you need to install the necessary driver for the modem and configure telephone connection to the operator. It’s difficult to give specific advice here, since everyone has different modems, and different operators. You can see the instructions for setting up a connection via a 3G modem.
Installing the 3G/4G modem driver
Everything is simple here. The driver may be on a disk that you may have been given when you connected to the Internet. There are many modems on which the driver is built into the modem itself. To check, connect the modem to your computer and go to "My Computer" (just "Computer" in Windows 7). There may be a drive or disk drive that appears after connecting the modem. We tear it off and start installing the driver. Sometimes, the offer to install software appears immediately after connecting the modem.
If these methods do not work, then look at the modem model and look for a driver on the Internet. Your operator's website should also have the necessary drivers.
Setting up a telephone connection
Once you understand the drivers, you need to create a connection. I don’t know how it is with all the operators (Beeline, Yota, MegaFon, etc.), but with Intertelcom, you need to create a regular telephone connection with a number, username and password.
To create it, go to the "Network and Sharing Center" and select "Set up a new connection or network" (see screenshots above). Next, select “Set up a telephone connection.”
Specify the necessary parameters provided by the provider (number, username, password). The computer will be connected to the Internet and a connection will be created. If an error appears that “Windows cannot detect the modem,” then check the modem driver. Or, to start, just restart your computer.
Very often, many users who for some reason had to reinstall the “seven” complain that afterward the computer slows down so much that it is simply impossible to work. Let's see what this might be connected with and discuss how to get out of this situation.
Why does my computer slow down after reinstalling Windows 7?
We will not dwell now on the reasons that prompted the user to install the “seven” again. Let's look at the problems that arise after this. Sometimes there is a very strong slowdown, the Internet does not work after reinstalling Windows 7, it is noted increased load on system resources or accessing the hard drive too often, etc. What could be causing this?
The very first thing users of desktop computer terminals need to do is check the strips random access memory and the connection density of the cables on the motherboard. You never know, maybe in system unit A lot of dust has collected, which leads to braking and freezing of the system.
On the other hand, it may very well be that the user mistakenly installed the 64-bit version of the “seven” instead of the 32-bit one (alas, this also happens), and the computer or laptop itself uses outdated hardware, which hardly meets the minimum system requirements. So it turns out that after reinstalling Windows 7, the computer slows down only for the reason that 64-bit Windows is much more power-hungry than the 32-bit version. But this is, so to speak, a general case. Now let's move on to finding out the specific reasons.
What drivers are needed after reinstalling Windows 7?
The presence of outdated drivers in the system can be called a fairly common phenomenon, because pure “seven” is also not the latest product. Additionally, if the user does not have original disc with drivers, which must be supplied when purchasing a computer or laptop, the system installs the most suitable ones from its own database, which, to put it mildly, is completely irrelevant.
IN in this case Once the OS installation process is complete, there is no need to rush (sometimes some drivers may not work). It is better to use special releases or update programs. For example, very good option may become a driver database that it is advisable to always have on hand.
On the other hand, it “weighs” quite a lot. Perfect for this situation free utility for search and under title Driver Booster. It works just fine, and it updates the drivers of absolutely all devices only when you contact official resources manufacturers, where, as a rule, the most current versions such software.
But there is one catch: if 7, install this utility It’s simply pointless, since no update will occur if there is no connection (more on that later).
The load on system resources is too high
Now we need to pay attention to one more point. Quite often there is an increased load on the processor and RAM, which is the cause of slowdown or freezing. What to do? See what process causes the maximum consumption of resources (as is known, in any Windows versions running by default great amount unnecessary services, which can and should be stopped).
First, call the standard “Task Manager”. This is done using the familiar combination Ctrl + Alt + Del or by entering the taskmgr command in the special “Run” menu bar (Win + R). Here you need to sort the contents in the processes and services sections by maximum load, and then see which component is loading the system.
Next you need to configure autoload. To do this, we use the msconfig command in the same “Run” menu and on the corresponding tab we disable everything unnecessary. You can only leave the antivirus, if one is already installed, and the keyboard indicator (ctfmon process). We uncheck all other services without a twinge of conscience (most users don’t need them at all anyway).
Internet problems
Now let's see why problems with Internet access are sometimes observed. First of all, if you are using, say, Wi-Fi, you should make sure that the corresponding module is enabled on your computer or laptop (the latter have a special key combination (most often it is Fn + some kind of function button, say, F5 - it all depends on the model).
If everything is fine here, you need to look into the settings of the TCP/IP protocol, which can be accessed through the Internet properties menu. In most cases, it helps to set the IP address to be obtained in auto mode and disabling the use of proxies for local addresses, unless otherwise provided by the provider. If all the parameters are entered manually, you just need to check that they are correct.
Finally, it may very well be that the network card has outdated driver. Therefore, it needs to be updated. To begin with, you can use the system’s own tools located in the “Device Manager”, or, which is much better, install the driver from the package described above. As a last resort, you can copy the DEV and VEN values in the list of equipment IDs on the description tab, and then use special sites to search for a driver using these values, and then download it from another terminal that has access to the Internet.
What's the result?
Here, in fact, we have looked at the main reasons why the computer slows down after reinstalling Windows 7. Of course, not all situations that may arise are given here. However, these are the most common. As for what programs are needed after reinstalling Windows 7, this issue has already been partially addressed. However, here you can add an antivirus, an archiver, an office suite, video and audio codecs and decoders, etc. But here the choice is up to the user himself. By the way, as an option, you can install some kind of automatic optimizer that will monitor the state of the system in real time and promptly unload unused or unnecessary processes from memory.
Installing or reinstalling an operating system is a very important and sometimes necessary procedure. As a rule, after it there are no programs left on the computer from the usual set that was there before. This is not only very inconvenient, but also dangerous for the device itself. After all, you need to install not only entertainment programs, but also applications responsible for the security and proper functioning of your computer under Windows.
Of course, for each user the set of programs that he needs will be individual. However, there are always some general programs, which must be installed on Windows 7 immediately after its installation and configuration. You must first install all the necessary drivers and codecs that are required for the PC to work, so that nothing interferes with the process.
What applications are definitely required?
List of what is needed for stable operation After installing a new operating system, the PC undergoes virtually no changes. Only the names and versions of the programs change, but the essence is still the same.
Antivirus
Almost the most necessary programs, without which normal operation computer on the Internet is unthinkable. It is also important that you need to install an antivirus first. Otherwise, there is a risk of picking up a bunch of nasty viruses when installing the rest of the software.
You should choose an antivirus carefully, based on various sources of information. Otherwise, you run the risk of downloading something that doesn't work properly. That is, it does not provide normal computer protection.
The next step is to find and download an archiver for yourself. Without it, there is a significant chance of not installing anything on your computer, since very often all programs from the Internet are downloaded in *.rar or *.zip formats.
The two most popular archivers – 7Zip or WinRar – can help with them. Each of them is convenient and practical in its own way, so the choice here is up to the user.
Browser
In any operating system, and even more so in Windows 7, after installation there is always at least one, even the most inferior, browser. Installs immediately by default Internet Explorer, with the help of which it becomes possible to download normal browsers. Of course, you can use it, but it usually slows down very much and makes working on the Internet as uncomfortable as possible.
The best browsers today are considered to be the three most advanced and developed ones, that is Mozilla Firefox, Google Chrome(as well as a bunch of browsers based on it, for example, Yandex.Browser) and, of course, the old lady Opera. Each of them has a special interface, some functions and other features.
Flash Player
A necessary plugin for the browser, without which it will not work normally. You will not be able to play music on any website, play a movie, or play any Flash game. You can download it immediately after installing the browser on the developer’s official website.
Work with documents
Next you need to provide yourself comfortable work computer with documents. That is, set normal text editor and others office applications, with the help of which you can conveniently interact with files.
As a rule, most computers with Windows 7 have a trial after installation. Microsoft package Office one of the versions. But after completing the test you will have to buy this product. And not every person can afford this.
And here you can make a choice. Buy yourself a licensed MS Office or settle for the not so convenient and familiar OpenOffice, even if it’s free. The package includes tools for working with all documents, including tables, presentations and text files.
This also includes a variety of readers and programs for opening and reading PDF files. By the way, PDF can be opened in a browser, and working with it will be no worse.
Further actions
When all the necessary programs are already on the PC, you can install the less important ones that may be useful to you someday.
Burning discs
If your PC has a CD burner drive inside the computer, then a program to burn data to the disc is vital. Who knows when this might be needed. Therefore, you need to attend to solving this problem as quickly as possible.
Of course, after installation, Windows 7 already comes with some kind of recording tool, but it is far from the most convenient. Some of the best programs for solving this problem are Nero or CDBurnerXP.
Creating Disk Images
Another very desirable one for Windows utility, which will appeal to everyone who works with disk images. As a rule, large games and applications are distributed as an image, so you need to open it first. And programs like this can help with this. Daemon Tools, with which you can read them, and Alcohol 120%, while working with which you can even create an image yourself.
Multimedia applications
Many users are unable to imagine themselves without catchy music or good movie. But without a special program installed on a PC, it is simply impossible to view anything. So, if you plan to watch or listen to something on your computer, you must first take care of installing programs such as Windows Media Player or KMPlayer, as well as WinAmp.
Messengers
The large number of ways to communicate via the Internet makes your eyes wide open. And very often such an abundance of programs confuses the unlucky user. As a rule, for a computer it is advisable to immediately learn:
- Skype/Viber/WhatsApp – special applications, available for telephone and computer, through which you can communicate with other users. After installation, two modes are available - call or write to the person they want to meet or chat with. Calls in these messengers are completely free and require only Internet traffic.
- ICQ/QIP and other old-style ICQ-like clients - made specifically for quick exchange messages. IN latest versions Calls are also available, although they are not as convenient as larger programs.
Applications for downloading from the Internet
There are entire software packages that are needed specifically to make it more convenient for the user to work with the network after installation. These could be various traffic or Internet speed meters, clients for more convenient sorting and downloading programs for Windows 7, and other equally useful utilities for your computer that can be found on the Internet.

Good afternoon dear visitors of the blog site. Probably each of you wondered what to do after installing Windows? What needs to be configured, install first.
Since the most popular OS is Windows 7, the installation of which I described, we will configure it directly, although this plan will be relevant for such versions as: Vista, 8, 8.1, 10.
Setting up Windows 7 after installation
Step 1: Activate Windows
The first step is to activate our system. If you have a key, it is entered during the installation process, or you need to go to Control Panel — system and safety— System, at the very bottom, find an inscription containing information that your copy is not activated until the end trial period left XX– days. If you click on this inscription, a window will open in which you will need to enter your activation key.
You can also activate Windows by phone, or use the best program for activation which I wrote about.
Step 2: Install the necessary drivers
If any drivers are not installed, then you need to use the disk that came with your computer or laptop, or update via the Internet.
It is important that even if the system has selected a driver for the video card and everything works and displays well, be sure to download and install the most fresh drivers from the video card manufacturer’s website, otherwise it will not work at its full potential!
Step 3: Disable User Account Control (UAC)
This service is aimed at ensuring computer security, monitors all processes in the system and notifies you about their activities with its constant “intrusive” messages.
By disabling it, you increase the risk of infecting your computer malware. But if you use antivirus software on your computer, you can disable this service in the Control Panel. See how to do this.
Step 4: Selecting and installing an antivirus
Settings Windows systems involves installing an antivirus. TO this process you need to take it seriously, because the security of your computer primarily depends on anti-virus software.
In my practice, I tried many antiviruses, each had its pros and cons. In the end, my choice settled on two antiviruses: Avast And Dr.Web.
I install the first one for clients who do not want to constantly search for keys or do not understand these nuances, and it is also installed at work, on all computers.
The second one is in my home, on my favorite computer, and protects it from all “nasties.” This antivirus I think it's the most optimal.
All the others that I used before, including nod 32, Kaspersky, Norton and others, in my opinion are much inferior to this antivirus product.
Step 5: Disable Windows Automatic Updates
Step 8: Windows visual effects, disable unnecessary ones on weak computers
Using shutdown visual effects on weak PCs, you can achieve a good performance increase.
But on any, powerful or weak computers I disable "Show window contents when dragging". For example, it is more convenient for me to drag a window and see what is under it.
Step 9: Set the paging file size for Windows 7 and other OSes
This file is used to store part running programs or any files in case of insufficient RAM.
Typically the system sets the default size relative to the installed RAM. If the amount of RAM is large enough, then the size of the paging file should be reduced; if, on the contrary, then slightly increased.
It can also be transferred to another HDD(if you have several), for more fast work systems.
Step 10: Enabling ReadyBoost
Step 13: Install the necessary programs for Windows
The first thing I always do is install the archiver WinRAR, necessary for viewing and creating archives. Then you need to install a program to open text documents, it could be either MS Office, or OpenOffice.
To play multimedia files, you need to install K-Lite Codec Pack , and some kind of player AIMP3 for playing music files.
These are quite popular and high-quality products that are easy to find on the Internet. You can also install CCleaner, to remove various garbage and clean the registry.
Step 14: Configuring Windows programs to start automatically, changing additional boot options
One of important points V Windows setup, affecting the boot speed of the system and desktop, as well as performance in general.
After installing the programs, you need to check autostart for availability extra entries, if there are any, then it’s worth removing them, since these programs will hang in RAM from the moment the OS starts, thereby increasing the time Windows startup and reducing productivity overall.
IN additional parameters download utility msconfig, It is worth setting the maximum number of processor cores that will be used when starting the operating system. This parameter will allow increase OS startup speed .
Step 15: Clean Windows from junk and defragment it
After installing the system and various programs There is always various garbage left: temporary files and so on that litter the system.
You need to get rid of them by using special program, For example, CCleaner. With its help, you can also clean the registry.
After cleaning the system, when there is no garbage or temporary files left in it, you need to defragment it system partition, which will improve system performance by arranging fragmented files sequentially on the disk.
Step 16: Disable autorun from removable media
To someone this function autorun from media is pleasant and convenient, but it carries with it hidden threat. Many types virus programs By autorun they infect computers while on a flash drive.
Step 17: Create a System Backup
When the system is maximally optimized and prepared for operation, it is necessary to make it backup copy – create an image of the system partition. It's done standard means Windows, called "Data Backup".
Ask why is this necessary? I answer:
A backup copy is necessary to restore the OS in cases of damage and inoperability. If you restore it from this image, you will have a “clean” one, without errors, working system. All installed programs and the settings made up to the sixteenth step inclusive will be saved!
Well, that’s all, dear friends, now you know what to do after installing Windows. I have briefly described the seventeen steps initial setup Windows. If you have any questions, ask them in the comments.
