Clear the registry from the program. Manual cleaning is a risk

The Windows Registry is an important part operating system, into which numerous data are entered - paths to installed programs, lists of used libraries, associations of file types with applications with which they should be opened, and many, many others. Almost everything you do in Windows is reflected in the form of a corresponding entry in the registry. The registry is often the target of attacks from critics of the operating system. Windows family and the solutions used in it. And there are good reasons for this.

The thing is that during the operation of the operating system, the registry becomes very similar to the mess in the room, which was created by a small child after several hours of entertainment with his favorite toys. Just like a child, the Windows operating system willingly creates various entries in the registry (takes out toys), but it is not very eager to erase entries that have become unnecessary (putting toys back in place). The problem is getting worse various applications, which are also not particularly clean and, after being removed from the computer, leave numerous unnecessary entries in the registry.

As a result, this leads to the fact that the registry grows significantly in size, thousands of non-functional entries appear in it, the reading of which consumes computer resources, which in turn slows down its performance. At such moments, the user usually decides that it is time to reinstall the computer operating system. In fact, this extreme measure of computer punishment can be significantly delayed if you try to clear the registry of broken entries.

How to clean the registry
It is practically impossible to clean the registry manually efficiently, since it contains tens of thousands of entries. Various utilities designed to clean the registry can help in this difficult task. The choice of programs in this class is huge, but among them there are many false registry optimizers that have an unreasonably high price and use aggressive marketing to convince users of their indispensability and high performance.

It is advisable to stay away from such programs, since in addition to the fact that they do not perform their functions properly, they may also contain various viruses. You can also use free programs to clean the registry. One such program is RegSeeker.

In addition to RegSeeker, we can also recommend another free program called Registry Life. Like RegSeeker, it finds unused entries in the registry and deletes them. It also has the ability to defragment and compress the registry, which increases the reliability and performance of the operating system. Windows systems on the computer.

While cleaning the registry, it is advisable to close everything running programs and do not perform any actions on the computer to allow the registry cleaning utility to do its best job.

For novice users, it may seem like a complicated and lengthy process. But there is nothing complicated here! Craftsmen have long developed special programs, which will find almost all the “garbage” in your registry, and you will only have to confirm the deletion of this pile unnecessary trash. So cleaning the registry is very easy!

Before we start reviewing registry cleaning programs, let me give you a little theory. Let's consider in general why to clean the registry and what it is, what its structure is.

The registry is a database in the Windows system. This database stores hundreds of parameters and settings of the operating system, installed programs and other data. Let's touch briefly on the topic of these programs that are stored in Windows system registry.

So, almost every program that we install on our computer enters a determination of the amount of data into the registry. But after removing this program, the data remains. It only deletes the files of its program, and not all of them, and leaves everything that it has entered in the registry in most cases. So imagine how this registry database can grow if you install and remove programs for a long time. But this is what happens, from time to time we use some on our computer, and some .

That is why you need to clean the registry once a month. Moreover, a “littered” registry database can cause poor performance. This, of course, is not a decisive factor why it might, for example, but I still recommend keeping the registry clean and tidy.

The registry has several main sections:

HKEY_CLASSES_ROOT;
HKEY_CURRENT_USER;
HKEY_LOCAL_MACHINE;
HKEY_USERS;
HKEY_CURRENT_CONFIG.

After downloading, install the program on your computer and run it. Now I will explain to you how to correctly CCleaner clean registry.

We need to go to the “Registry” tab, make sure that opposite all the items in the parameter “ Registry integrity“check all the boxes and click the “Search for problems” button.

When the program completes the analysis, it will offer to fix the problems found. Click the "Fix" button.

We will be prompted to make backup copies of the changes we have made. As I understand it, this is just in case if after running the program the registry starts to not work correctly. I completely trust the program, so I click “No”.

We confirm the correction of the problems found, at the discretion of the program, by clicking “ Correct marked" The program will remove unnecessary things and try to fix what happens.

Do this operation to find and remove problems in the registry until everything is fixed.

With this fairly simple utility you can easily find what you left behind. remote programs And clean the registry V automatic mode.

Of course, not always registry cleaning leads to the desired result, for example, the computer is still not stable, glitches or slows down. In this case, you need to look for a reason elsewhere. But an operation to clean the registry is still necessary from time to time.

It is also advisable to understand the registry so that, if necessary, you can not only delete something unnecessary, but also restore it, for example, after a virus attack. But that's a completely different story.

That's all for today, I hope my instructions on how to clean the registry will be useful to you. And most importantly, do not forget to scan and find problematic entries in this huge database once a month using the CCleaner program.

The registry cleaning is completed, I wish you success in completing this operation too!

), at best, only the “body” of the program was deleted, but much of it remained in the bowels of your computer. Most beginners cannot even think about this, and remember only when, under the weight of junk from various software garbage, your system begins not only to sag, but also to crack at the seams, producing, for example, all kinds of “blue screens”.

TO Cleaning the Windows registry must be approached very competently and carefully. By at least this is not for beginners. Moreover, it is not recommended to entrust all kinds of programs to work with the Windows registry, even if they are super cool

ATTENTION: If you decide to clean the Windows registry, be aware that you will have to work with nothing but the Windows registry - the holy of holies of the system, and careless handling of this very registry is like waltzing on a minefield. If you neglect the registry, problems may arise . You can only delete files that are familiar to you

Yeah! Now I’ll start teaching here, like most of my fellow admins on similar sites, they say, launch the registry editor, erase this and that there... No, no :o) First of all, backup, backup and backup again. For those who are not in the know and don’t know what backup is, it’s creating a backup copy of data in case something goes wrong. This is how a computer magically differs from a vacuum cleaner, which allows you to almost always “roll back” to an earlier, working state if you manage to “tamper” with your system, including by not carefully reading this lesson.

Step one: Make a system backup...

So, it means that we are making a backup of the system and registry: and we are doing all this as standard using Windows. And the last “Chinese” warning:

If you do not have original Windows(assembly) - it is better to refrain from using any of the recommendations outlined in this article, since cleaning the registry on a broken Windows is triple risky!

Further, so that no questions arise, I will describe the procedure for each Windows versions, separately for XP and separately for Windows Vista, Windows 7. Please do not confuse anything, be careful. If you doubt your abilities, it’s better to refrain from experimenting!

If for any reason the System Restore function was disabled on your computer, you must enable it, then make a restore point. In Windows XP this is done like this: On the menu Start right-click on the icon My computer and select the item Properties. In the window that opens Properties of the system find and click on the tab System Restore. Check the box Enable System Restore. Now you can safely press the button OK.

But that's not all: now we need to create the system restore point itself. To do this, you need to perform the following sequence of actions (let me remind you, this is for XP): Start — Programs — Standard — Service — System Restore and there click on Create a point. Another way is possible: Start — Execute, enter there rstrui and press Enter and then as in the first method.

Now I will describe how to enable System Restore and create a checkpoint in Windows Vista, Windows 7. Due to the similarity of these two systems, the steps described below will be valid for both versions: To do this, you need to log into the system under account with administrator rights. Next click Start, right click on Computer and select in context menu Properties. In the nameless window that appears, on the left panel, click System protection. If you are prompted for administrator rights or confirmation of consent, enter your password (again, if necessary) or confirm. In field System parameters select drive C (or the drive on which you have Windows 7 installed) and click on the button Tune. Next you need to click on Restore system settings and previous versions files- this is important, because God forbid, of course, but we may have to restore system settings And previous versions files. And now, without leaving this window, you need to press the button Create. Specify the name of this control point and click Create. Windows will tickle the green bar a little and give you a congratulations message saying it was created successfully! Now click OK, once again OK. At this point, the preparatory stage can be considered complete.

Action two: we are looking for what we need to clean...

And again, I won’t talk about how to delve into the registry yet, because it’s a little early... First, we need to thoroughly decide what exactly to clear in the registry, and only then we’ll start cleaning the registry directly. In other words, measure seven times and clean once!

Before deleting any program, find out who its developer is. This will be useful to you in the future to correctly clean the registry from this program. The fact is that program developers like to create in the registry when installing their program on a computer. Windows records with the name of your company. Moreover, it sometimes happens that when a company changes its name, the corresponding registry entries that are created when installing their program have exactly the old name of the developer (probably this was done for compatibility).

For example, if we take the famous Nero program for burning discs, we find that the Nero program has a developer company of the same name, focusing on one of its successful products. Nevertheless, more experienced comrades will not let me lie that the Nero company used to have a different name - Ahead. Therefore, in the Windows registry, and even in the names of the folders where the program is installed, the name Ahead is also found, as it now turns out, associated with Nero program. Yes Yes! It turns out that it is not so easy to clean the registry; you need to know a lot before doing this. And how can you now entrust cleaning the registry to some stupid cleaning program?

Step three: Correctly remove the program that we no longer need...

Perhaps we’ll practice on Nero. Moreover, you and I know two magic words Nero and Ahead. Let's remove this wonderful program from our computer. Let's go to Start — Control Panel and for Windows XP Installation and removal of programs, and for Windows 7 (Vista) in Programs and components. But even here, not everything is so simple. It turns out that Nero is a whole complex of programs, and this is also necessary to know. For example, if you suddenly no longer need Microsoft Word, most likely you will not find it in the list of installed programs. Because Microsoft Word is included software package Microsoft Office, so you’re unlikely to be able to remove Word separately from Office (although it’s possible).

Therefore, we remove one by one all the programs included in Nero. To do this, double-click with the left mouse button on each program: Nero Burning Rum, Nero Express, and so on until all programs labeled Nero disappear from the list.

When you are finished with uninstalling programs, go to My computer - Drive C - Program Files and look there for folders with names containing our two cherished words: Nero and/or Ahead. Very often such folders remain, although the program itself no longer exists. We delete these folders in Cart. For Windows Vista and 7 we need to check in one more folder - Program Data. To do this, the display must be turned on hidden files. I don’t want to repeat how this is done - you can read it. Don't be upset or surprised if in folders Program Files And Program Data, you won't find specified folders- some programs behave correctly and completely remove themselves upon uninstallation, but it never hurts to check this.

And that’s not all - don’t be lazy and look (if in Windows XP) into the folder C:\Documents and Settings\Username\Application Data, and C:\Documents and Settings\Username\Local Settings\Application Data, and it’s even easier to use search and find all folders with names containing Nero and Ahead. In Windows 7, thanks to its improved search, this will be made even easier, and we also delete these folders (Nero and Ahead) to the Recycle Bin.

When the correct removal of the program is finally over, we move on to the most important and important part of our entire undertaking...

Step four: Clean the Windows registry...

Click Win+R and enter into the launch line regedit and click on OK, launching the Windows Registry Editor in this simple way. On the left side you will see section K computer, expanding it by clicking on the triangle you will see sections

*HKEY_CLASSES_ROOT*,

*HKEY_CURRENT_USER*,

*HKEY_LOCAL_MACHINE*,

*HKEY_USERS*

*HKEY_CURRENT_CONFIG*.

*HKEY_CLASSES_ROOT* we will skip, there is nothing there for us.

Method 1. Cleaning the registry

Now... Noooo! We don’t clean anything yet, but again make a backup copy, now of the registry itself. To do this, left-click on File - Export... and save the Windows registry in a file with the extension .reg, preferably on another drive, not on C . Now, with peace of mind, you can finally start editing and cleaning the registry. In the registry editor, click once on the inscription Computer(or My computer in Windows XP), and then press the keyboard shortcut Ctrl+F a search window will appear. First enter the word Nero there and click OK. The computer will “think” a little and give you a registry branch in which you will see the word you are looking for. We carefully look at what is written there, if the path to the program is written, for example C:\Program Files\Nero\..., etc. - it is obvious that this path belonged to the program we deleted. We delete this entry from the registry. Then press the key F3, and the search finds us the next value which contains Nero. Or we’ll see a whole section called Nero in the Software section, delete that too. And so we repeat our actions cyclically until the registry editor gives us the phrase Registry search completed- this means we have reached the end of the registry and the program will not find anything for us.

We repeat the same thing with Ahead. And so we clear the registry from the program. After this, close the registry editor and restart the computer. If the computer boots normally, it means everything worked out for you, and you can run to brag to your friends and acquaintances that you manually cleaned the Windows registry yourself!

This is how you can correctly and without a trace remove programs from your computer and clear the Windows registry of no longer needed deleted programs, and having become more experienced in this matter, you can even remove some viruses manually, without an antivirus! Don't forget to be careful and attentive! And also, remember! Not even the most vaunted cyclinizer will ever replace your mind and hands. For lovers of portable programs, I will give one more parting word - keep in mind that not always, of course, but quite often your favorite “portables” also clutter up the registry with their entries. It all depends on the kulibin who made this very portable.

Method 2. Manually clear the registry of programs.

Expand * HKEY_CURRENT_USER*, open the section *Software*. Now we read the entire list of folders, there will be many programs that you deleted a long time ago, but a record of them remains. And these records clog up and slow down your computer.
And, unfortunately, not all programs see and delete them. Therefore, when we see such an entry, click on it with the second mouse button and select *delete*, or simply select this folder and press the Del button on the keyboard. Please note that all (or many, depending on the situation) settings of this program will be erased, and the next time you install them you will have to set them again. But it's not that difficult.

Now collapse *HKEY_CURRENT_USER*, open *HKEY_LOCAL_MACHINE*, there is a section in it *SOFTWARE*. And we also look for and delete unnecessary entries. Delete entries only for those programs that have been removed. Otherwise the program may stop working. When you have cleared this section as well, close *Registry Editor*. Restart your computer. All.
