Surely, no one needs to explain that very often many users of modern PCs encounter a slowdown in the operation of a computer terminal. Unfortunately, it is often observed that it is the Svchost process that loads the memory and processor. Let's see what this process is and how to get rid of unnecessary load on system resources.
What is the Svchost.exe process?
First you need to figure out what kind of service it is and how it works. Naturally, each user, entering the “Task Manager” (Task Manager) when entering a command in the menu “Run” or when called using the keyboard shortcut Ctrl + Alt + Del in the process tree, observes not one, but at least four to five processes Svchost.exe doing incomprehensible what.
Do not immediately panic. It should be so. In fact, this is a system service that was used by Microsoft specialists in Windows systems relatively recently. This refers to the fact that before this process exclusively functions were assigned that were responsible for the correct network connection or Internet connection.
This in no way affected the launch of applications. Then the developers added a headache to the service and assigned it responsibilities related to accelerating the launch of programs and their components after the start of the Services.exe service. So it turned out that intentionally or unintentionally Svchost loads the memory of Windows 7, as they say, despite the faces and ranks. Here a situation appeared, which in Russian can be described as "they wanted the best, but it turned out as always." Nevertheless, it is possible to deal with manifestations of excessive load, but first we’ll look at how this service affects the system.
Why the Svchost.exe process loads the system
First of all, it is worth saying that the developers tried to make a single service, which should be responsible for launching all programs. On the one hand, this is very good. Why run a bunch of unnecessary components to start this or that process? In particular, this concerns the call of data from the so-called dynamic .DLL libraries. By themselves, such files are not executable, but only work through hosts.
The simplest example is the use of RTAS, DX or VST plug-ins connected to audio, video editors or special music sequencers via DirectX bridge or serving drivers such as ASIO4ALL.
So it turns out that good intentions did not lead to anything good. The one and only service received excessive load, as a result of which the Svchost service loads the memory so that neither the processor nor physical memory (swap file) can cope with such a load. Judge for yourself, because you can simultaneously open up to a dozen applications on a computer terminal or laptop. Some people like to play their favorite game while listening to music. But all this is launched precisely through Svchost.exe.
Well, if you take into account that there is an Internet connection, the whole system can freeze, because the service itself, as mentioned above, combines not only the functions of launching applications, but also the priorities of network connection and access to the World Wide Web . Here it is worth considering the fact that if an online game is used, and it is quite resource-intensive, not only the Svchost.exe service will work. Netsvcs loads memory no less. This is an accompanying process when connecting to a network or accessing the Internet.
How many processes can be started simultaneously
When a user senses or observes in the process tree that the Svchost service is loading RAM and the CPU, it immediately starts to panic, because the list contains at least four identical services. No worries. Depending on the number of running applications and the availability of an Internet connection or a local network, there can be many more (up to a dozen or more). Some people think that these are viruses, and try to complete everything that is possible, and then remove the related components and the program file itself. It is not right. A little later we will talk about how to distinguish a normal process from malware.
The simplest method to end the Svchost.exe process
So, we have a situation where Svchost loads Windows 7 memory too much. How to get rid of this in the simplest way? Yes, very simple. You just need to restart the computer terminal.
After a reboot, the use of system resources from calling applications will decrease quite significantly.
You can do otherwise and go to the "Task Manager", called from the command line or with the usual keyboard shortcut Ctrl + Alt + Del, on the "Processes" tab, find the service we are interested in (in this case Svchost.exe) and click the "End Process" button.
In this case, you need to choose exactly the component that has the most negative impact on the use of the processor or RAM. Naturally, all other processes can be completed.
Removing process components
In some cases, there is a situation where Svchost.exe is loading the processor. What to do in this case?
Some experts recommend using the physical intervention method and stopping the service by deleting the Prefetch folder located in the Windows root directory (C: \ WINDOWS \ Prefetch), after which you will need to complete the process tree and reboot the system. Nothing terrible will happen.
Svchost.exe process attributes
As for attributes, the Svchost.exe process never starts on behalf of a user, even if he is an administrator on a specific computer terminal or server.
Only three options may be present in the process description: LOCAL SERVICE, SYSTEM, or NETWORK SERVICE. Everything that has other attributes can be completed without hesitation and without a twinge of conscience.
Suspected Viruses
Of course, there may be a situation where it is clear that the Svchost process loads memory for no apparent reason, and the service attributes do not match what was stated above. In that case, you can be sure that it is a computer virus. Of course, such a process can be completed manually, but it is strongly recommended that you check the system with some powerful anti-virus package. True, this also does not always help, since viruses disguise themselves as a service quite well and can even hang in RAM.
Here it is better to use applications like Dr. Web Rescue Disc or Kaspersky Rescue Disc, which start before Windows starts up. Such applications are able to detect viruses even in situations where a standard anti-virus threat misses or simply does not find.
Conclusion
That, in fact, is all. With general concepts why Svchost loads memory or processor, and how to complete this service, we figured it out. All that remains is the question of whether to stop or delete the process. If this is a regular process, it is not worth completing it even on low-power machines, it is better to wait a bit until the service stops accessing any data or libraries. Well, as a last resort, you can just reboot the system or close problematic programs. It’s better not to get into the system itself.
Upon completion of the process in the "Task Manager", a spontaneous reboot may occur, or even worse, the occurrence of a blue "death screen". Then you will have to deal with Windows recovery or even a complete reinstall. And these, as you know, are extremely undesirable processes. In addition, for sure, no user will want to reinstall Windows 7 or restore it from the console, since this is a rather troublesome business. And such a process takes a lot of time, not to mention preparatory operations.
