The first step is to try disabling applications one by one. Indeed, a low-power device can easily be overloaded by simultaneously running several heavy-duty applications.

Second. Often the cause of problems is prolonged active surfing on the Internet. The system is littered with hundreds of megabytes of temporary files. The registry is confused. There are two options here.
1. Run the cleaner and remove everything unnecessary files, repair the registry and perform a basic defragmentation.
2. Didn't help? Then open System Restore and rollback to more early state. It is almost never possible to restore normal performance in one go. Usually no more than three restorations are sufficient.

And don't forget to create rollback points. Does the computer fly? Go to Recovery and create a return point. It will come in handy.

The next assumption is that the computer was penetrated evil virus. If possible, run a scan. You need to be patient, drink some tea, take a nap. In such a relaxed state of the system, scanning will take a long time.

Another classic cause of system overload is the svchost.exe process.

What is it and why does it interfere with the operation of the computer? The svchost.exe process is one of the auxiliary system services, involved in many other tasks. The thing is useful, but sometimes it's buggy. What can disrupt this process?
1. Physical damage memory chips. A lot of dust has accumulated in system unit. Service centers It is recommended to vacuum the inside of your computer at least once a year.
2. Errors when downloading automatic updates. For example, during the update process there were interruptions in the Internet connection or power outages. Facts have been noted where the update packages themselves were initially delivered with bugs. Even Microsoft experts themselves admitted this.

In cases where problems are caused by bad updates, it is recommended to go to the official Microsoft website and download a proven and reliable package, then install it yourself.

Viruses are often disguised as svchost.exe processes.

It is very convenient for hackers to present a virus or Trojan under the guise of the svchost.exe process. The system will issue a notification about unknown error and for now the user will be able to figure out the reasons. First you need to find out if he is guilty svchost process.exe? To do this, open the Windows Task Manager (Alt+Ctrl+Del) and go to the Processes tab.

There will be at least four svchost.exe processes. Now look at the load level for each process. If some svchost.exe process has a load close to 100%, this is the culprit of the problems. What's next?
1. To begin with, it is always recommended to reboot the system. Most often the problems disappear.
2. If everything happens again, open the Task Manager again and end the overloaded svchost.exe process. To do this, open context menu(right mouse button) and click End Process Tree. Restart your computer again.
3. Didn't help? Now the surgical method. Open Windows Explorer. Find the Windows folder. Select the folder C:\WINDOWS\Prefetch. Delete this folder. Then open Task Manager again and end the tree of the overloaded process svchost.exe again. Restart the computer.

Basically, if the problem was actually a random crash of the svchost.exe process, everything should be fine. If problems continue, the cause should be looked for elsewhere. Might have actually happened viral infection. Then you need to take a closer look at all the processes and try to identify the disguised virus.

Signs of a virus disguised as the svchost.exe process

Normal svchost.exe processes run under the username:
- SYSTEM LOCAL SERVICE
- NETWORK SERVICE

Or something like that. Viruses hide under the username ADMIN or whatever you logged into account Windows user.

If a misdirected Cossack is detected, complete its tree and thoroughly clean the system with antivirus. Don't be afraid if you accidentally kill the normal svchost.exe process. Smart Windows system It will just automatically reboot.

Be sure to install a decent antivirus package if you use the Internet. Especially if you like to explore new sites, experiment with programs and other eighteen-plus entertainment. Download the healing utility Dr. Web CureIt. Copy it to a flash drive and store it for a rainy day. This program does not require installation and is capable of finding and neutralizing viruses on already infected systems.

Save for the rainiest day Windows distribution and make backups of important documents in a timely manner.

No introduction, straight to the point. The computer or laptop was working perfectly and, suddenly, the image on the screen and the cursor began to twitch. This usually happens when the central processor and RAM are loaded to the limit of their capabilities (up to 100%).

This situation may occur if one or more processes, services or programs consume a lot of laptop or PC resources. Svchost loads the system (processor and memory) due to errors and shortcomings in the program itself, problems in Windows OS or insufficient computer resources (weak processor, low RAM, etc.). How to remove svchost?

To understand which processes cause slow work system, you need to go to the Windows “Task Manager” (Ctrl+Alt+Del) and open the “Performance” tab. For detailed information you need to click on the “Open resource monitor” link.

What processes most often load and greatly slow down the operation of a laptop and computer:

• Svchost.exe (netsvcs, LocalServiceAndNoImpersonation) - problems with installing drivers on some devices. The Svchost.exe process is used during the operation of some network services (belongs to the networkservice type). The activity of the Center has the strongest impact on the performance of a computer or laptop. Windows updates»;
• Svchost.exe (netsvcs, LocalSystemNetworkRestricted) - problems with the Superfetch service and Windows Update. Superfetch, what is this service? Superfetch is used to speed up access to frequently used files, folders and programs through advanced caching. In some cases and with certain configurations of a computer or laptop, the service can either speed up work or greatly slow it down. Using Superfetch for SSD+fast RAM over 4GB=doesn't make sense. Whether or not to disable Superfetch and Prefetch is up to you;
• MsMpEng.exe – Antimalware Service Executable, Microsoft Security Essentials, executable file built-in antivirus program ( firewall) in Windows 10. Another name Windows Defender or Windows Defender.

Popular questions about the Svchost.exe program.

1. Svchost.exe - what is this process? This is a standard host process for Windows services 10 (7, 8, etc.).
2. Why are there many processes running with the same name svchost.exe, is this normal? Because many services and Windows components use this process in their work. These are mainly network services and various devices computer or laptop. Don't be afraid, this is not a virus, but a normal Windows system process.
3. Why does svchost.exe netsvcs (localserviceandnoimpersonation, localsystemnetworkrestricted) waste memory and CPU? This process can put a lot of stress on the system during peak load times, such as when checking, downloading Windows updates from the Internet, and installing them. Congestion may also be caused by driver installation or malfunctioning devices and components. If resource-intensive programs are running at this moment, try closing them and wait a little. If the problem is not solved even by rebooting, then you need to take action.

If the processor or RAM is not heavily loaded, but the computer still freezes a lot, the problem may be in the hard drive. Old HDDs can greatly slow down the operation and performance of the entire system as a whole. Check the disk for errors and try to copy something from one folder to another; if the process takes a long time, the hard drive needs to be replaced.

How to disable services and processes that use memory and CPU:

1. How to disable svchost.exe (netsvcs). To disable the Windows Update service, you need to launch the Task Manager by pressing Ctrl+Alt+Del. Select the “Services” tab and click “Open Services” at the bottom. Find the Windows Update service, click right click- “Stop.” Then right-click on the service again and select “Properties”. In the startup type, select “Disabled” from the drop-down list and click “OK.”
2. How to completely disable, remove Windows Defender 10, 7 (MsMpEng.exe) permanently. It is highly not advisable to remove Windows 10 Defender. It is necessary to at least somehow protect the system from viruses, if no other anti-virus software is installed. When installing any other antivirus (ESET Nod32, Kaspersky, DrWeb, Avast, etc.) Windows Defender 10 and standard firewall automatically turn off. To disable the Defender service manually, you will need to edit the registry. Disabling Windows Defender is only required in extreme cases; usually the problem is resolved without this.
3. How to disable Superfetch Windows 10. It turns off in the same way as svchost.exe (netsvcs), only we look for “Superfetch” among the service names.
4. How to disable Prefetch. If you are going to disable the sysmain superfetch service in Windows 10, it makes sense to disable the Prefetch service along with it. Both of these services were created to speed up programs and improve productivity on weak computers. Superfetch and Prefetch show good results for slow ones hard drives with low read/write speed. On more or less modern laptops and PCs with SSD and DDR4 can be safely disabled. Samu Prefetch folder V Windows directory, it's better not to touch. Disable only the service itself in the registry.

If you have a choice of installing Windows 10 Defender or antivirus, choose a good antivirus package. Windows Defender (msmpeng.exe) or Antimalware Service Executable is a temporary measure to combat viruses and is not effective enough to prevent serious cyber threats. The msmpeng.exe process in some cases heavily loads the processor and memory.

If none of the above helped, I highly recommend studying these 3 threads on the forum technical support Microsoft:

• Here is a detailed description of the solution to the issue from LocalSystemNetworkRestricted -
• Here about Windows 10 Defender (MsMpEng.exe), what to do if it loads the processor and memory -
• Once again about possible problems with svchost.exe (netsvcs) -

Here are some simple ways to deal with slowdowns on your laptop and PC. I'm waiting for questions in the comments. Good luck and good luck! 😉

Svchost.exe is a process that is known to consume large percentage CPU resources, in other words, at times heavily load the processor. You've probably been in a situation where you're working at your computer, happy with everything, and then the system starts to freeze. You press CTRL+ALT+DEL, open the “Task Manager”, click on the “Processes” tab, and see that there are several processes running in the system svchost.exe, one of which loads the processor by 50% - 100%. Someone might think: “Oh my God, I have a virus on my computer!” Well, that may be true, because some types of malware masquerade as “svchost.exe”, but most likely it’s just a regular Windows work.

So why is svchost.exe so important? Svchost is a tool for launching services and DLLs. In the list of processes, you saw many .exe files that run independently, but this does not apply to DLLs - they cannot be launched as an independent unit. They are launched by Svchost.exe.

The question arises, how to resolve the error in which Svchost.exe heavily loads the CPU. First, you need to identify the service that was started by that copy of Svchost.exe that is consuming a large percentage of the CPU. To do this you need to use additional utilities, one of which is Process Explorer, written by programmers former company Sysinternals, which is now part of Microsoft. So, unpack the archive and run the .exe file. In the program window we find the svchost.exe process that loads the system and simply hover the mouse cursor over it. A pop-up card appears with information on which we see the service launched by this copy of svchost.exe.

Now, if this is not a Windows process, you just need to end it and remove the program that launched this problematic process. If you cannot find this program, then it may just be a virus. Use it and then install it.

However, most likely, our problematic svchost.exe process will serve to launch one of Windows services, such as Task Scheduler, Firewall or Collector Windows events. Sometimes simply restarting your computer will solve the problem. If this does not help, the first thing to do is install the latest Windows updates.

If for some reason you cannot install updates, then you need to open the Windows service management tool and deactivate the one that is causing problems. To do this, in Windows XP, open Control Panel – Administrative Tools – Services. In Windows 7: Control Panel – System and Security – Administrative Tools – Services (or write in command line services.msc and press Enter). Find the required service (service), right-click on it and select Properties. On the first tab, in the Startup type list, select Disabled. In the future, you can always enable this service. After this, you still need to download updates from the Microsoft website and install them, and then try to enable the service again. The error should be resolved.

There is another way to get rid of high load processor side svchost.exe. To do this you need to open the Manager Windows tasks"(press CTRL+ALT+DEL), find the process causing the problem, right-click on it, move the mouse to the "Priority" item in the menu and set it to "Below Average" (or "Low" if "Below average” doesn’t help). However, be aware that setting the priority to Low may affect other issues.

Also, in case common mistakes related to the svchost.exe process, cleaning it may help system registry. To do this, you can use one of the utilities, for example, (just don’t forget to make backups before cleaning).

Svchost exe loads the processor 100% in Windows 7, what should I do?

From the article you will understand what needs to be done if Svchost.exe loads the processor at 100%. Is it a virus or not? Now let's see, many people have had situations when the PC starts to freeze and after calling the task manager you will notice that a process called Svchost.exe loads your processor almost 100%. Of course, no one will like it and everyone will want to turn it off or delete it.

Many people will immediately think that it is a virus. Looking ahead, I’ll say that maybe it’s a virus (numerous viruses disguise themselves as system files), or maybe not. In Windows 7, there are several services that are called by this name. Now I'll try to fix it this situation and stop the process that is unnecessary for you. Let's start:

What to do if Svchost.exe loads the processor

1. I launch the task manager by simultaneously pressing Ctrl+Alt+Del on the keyboard.

2. Having launched the dispatcher, go to the Processes tab and click on Display processes of all users at the bottom.

3. I will sort the processes by clicking on the Image name section. Then I will find Svchost.exe and right-click on it. In the menu window that appears, select Go to services.

4. In the Services tab that opens, all services that Svchost uses will appear.

5. You have to find the service that loads the processor to the maximum. To do this, you need to disable all of the above services in order. I right-click on the service and click on the Stop service link.

Important! After each service is turned off, check the result.

It is not possible to completely disable this service using the task manager. It will of course be stopped, but not turned off. After rebooting the PC, it will start working again and load the processor.

Another one good reason, according to which the svchost process loads the system - active work automatic update. If it is turned on and works successfully, then it is likely that the problem really lies with it. To solve this you will need to disable automatic updates.
The next method that I can suggest to you to fix this problem is cleaning the registry operating system.

And the last option, in my opinion, is if a virus disguised as system file Svchost, then you need to check your computer carefully antivirus program.

So, conclusions:

Practice shows that often, in addition to unwanted applications, the problem is simple updates operating system. All other cases can be considered “special”, because in almost every one of them everything is “tied” to specific application. For this reason, it is impossible to describe all cases.

SVCHOST.EXE is one of the important processes when running Windows OS. Let's try to figure out what functions are included in its tasks.

SVCHOST.EXE can be seen in the Task Manager (click to go Ctrl+Alt+Del or Ctrl+Shift+Esc) In chapter "Processes". If you do not see elements with a similar name, then click “Display processes of all users”.

For ease of display, you can click on the field name "Image name". All data in the list will be arranged in alphabetical order. There can be a lot of SVCHOST.EXE processes: from one and theoretically to infinity. And practically the number of active simultaneously active processes limited by computer parameters, in particular CPU power and size random access memory.

Functions

Now let us outline the range of tasks of the process under study. It is responsible for the operation of those Windows services that are loaded from dll libraries. For them, it is the host process, that is, the main process. Its simultaneous operation for several services significantly saves RAM and time for completing tasks.

We have already found out that there can be many SVCHOST.EXE processes. One is activated when the OS starts. The remaining instances are launched by services.exe, which is the Service Manager. It forms blocks of several services and runs a separate SVCHOST.EXE for each of them. This is the essence of saving: instead of running separate file for each service, SVCHOST.EXE is activated, which unites a whole group of services, thereby reducing the level of CPU load and the consumption of PC RAM.

File location

Now let's find out where the SVCHOST.EXE file is located.

Why does SVCHOST.EXE load the system?

Relatively often, users encounter a situation where one of the SVCHOST.EXE processes loads the system. That is, he uses very a large number of RAM, and loading central processor from activities of this element exceeds 50%, sometimes reaching almost 100%, which makes working on a computer almost impossible. U similar phenomenon There may be the following main reasons:

• Substitution of a process by a virus;
• A large number of simultaneously running resource-intensive services;
• OS malfunctions;
• Problems with the Update Center.

Details about solutions mentioned problems is described in a separate material.

SVCHOST.EXE – virus agent

Sometimes SVCHOST.EXE in the Task Manager turns out to be a virus agent, which, as mentioned above, loads the system.

1. The main sign of a viral process, which should immediately attract the user’s attention, is its large consumption of system resources, in particular the high CPU load (more than 50%) and RAM. To determine whether a real or fake SVCHOST.EXE is loading your computer, activate the Task Manager.

   First we pay attention to the field "User". IN different versions OS it can also be called "Username" or "User Name". Only the following names can match SVCHOST.EXE:

   • Network Service;
   • SYSTEM("system");
   • Local Service.

   If you notice a name that matches the object being studied with any other user name, for example, the name of the current profile, then you can be sure that you are dealing with a virus.



2. It is also worth checking the location of the file. As we remember, in the vast majority of cases, minus two very rare exceptions, it must correspond to the address:

   C:\Windows\System32

   If you find that the process refers to a directory different from the three discussed above, then you can confidently say that there is a virus in the system. Especially often the virus tries to hide in the folder "Windows". You can find out the location of the files using Conductor in the manner described above. You can use another option. Right-click on the item's name in the Task Manager. From the menu, select "Properties".

   

   A properties window will open, in which, in the tab "Are common" there is a parameter "Location". Opposite it is the path to the file.



3. There are also situations when the virus file is located in the same directory as the genuine one, but has a slightly changed name, for example, “SVCHOST32.EXE”. There are even cases when, in order to deceive the user, attackers, instead of Latin letter“C” is inserted into the Trojan file using the Cyrillic “C” or “0” (“zero”) is inserted instead of the letter “O”. Therefore you need to pay Special attention to the name of the process in the Task Manager or the file that initiates it, in Conductor. This is especially important if you see that this object consumes too many system resources.



4. If your fears are confirmed and you find out that you are dealing with a virus. It should be eliminated as quickly as possible. First of all, you need to stop the process, since all further manipulations will be difficult, if not impossible, due to the processor load. To do this, right-click on the virus process in the Task Manager. Select from the list "End process".



5. A small window opens where you need to confirm your actions.



6. After this, without rebooting, you should scan your computer with an antivirus program. It is best to use the application for these purposes, as it has proven itself in the fight against a problem of precisely this nature.



7. If using the utility does not help, you should delete the file manually. To do this, after completing the process, move to the directory where the object is located, right-click on it and select "Delete". If necessary, then dialog boxes we confirm the intention to delete the element.

   

   If a virus is blocking the removal procedure, then restart your computer and log in to Safe Mode (Shift+F8 or F8 while loading). Eliminate the file using the above algorithm.

Thus, we found out that SVCHOST.EXE is important system process Windows, which is responsible for interacting with services, thereby reducing the consumption of system resources. But sometimes this process may be a virus. In this case, on the contrary, it squeezes all the juice out of the system, which requires an immediate response from the user to eliminate the malicious agent. Additionally, there are situations where, due to various glitches or lack of optimization, SVCHOST.EXE itself can be the source of problems.
