Users of the seventh modification of Windows very often encounter a problem when a certain process of Windows 7 Svchost.exe loads the processor. The solution to the problem, as it turns out, lies on the surface. However, in order to determine exactly what methodology to use to correct the situation, you first need to figure out what the given process and related service components are, since disabling some of them can provoke not only incorrect operation of the OS, but also the appearance of more unpleasant symptoms (even a blue screen is not ruled out).
Svchost: what is this process?
Since the problems of increased load by this service are most often observed precisely in Windows 7, and almost never occur in systems of later releases, when considering all aspects, we will start from the seventh modification.
What kind of component is it that it consumes such an incredible amount of system resources? This is a specialized tool for launching system and user programs, which, according to developers from Microsoft, is supposed to reduce the load on the system at the time of launching programs and their executable components, for example, presented in the form of dynamic libraries loaded at startup of the executable component as additional objects in RAM.
Speaking in a simpler and more understandable language, in Windows 7 the system itself does not need to run each application as a separate process, since only one main component is used for this, due to which all programs start, being sort of tied to it. And the Svchost process is a kind of intermediary bridge between the launched program and the main system component responsible for its launch. That is, all starting programs and processes through this component are connected to a single launch service.
Why are there too many processes of the same name in the Task Manager?
But the main start service in the same "Task Manager" is not displayed. In it you can see just the processes of the same name Svchost, which in the normal state of inactivity can be of the order of four, and if there are working programs, and even more.
Thus, if Svchost is loading the processor and memory, Windows 7 is simply currently processing too many active background (system) and user applications. But many of them can be quite resource intensive (take at least AutoCAD or real-time video processing software). In such situations, usually in Windows 7 Svchost loads the processor by 50% (maybe a little more). If peak loads are noticed when the operating system freezes and stops responding to any user actions, you will have to find out the reasons why this happens.
Windows 7: Svchost loads the processor 100%. Why?
As for the causes themselves, there can be quite a lot of them, and such situations can not always be triggered by systemic failures (although, unfortunately, this is not without them).
But back to the situation where in Windows 7 Svchost.exe loads the processor too much. The most likely causes of this phenomenon are the following:
- short-term malfunctions of system processes;
- viral infection;
- problems with the system update service;
- too many or failing related services and system components;
- incorrect operation of the tunnel adapter;
- problems with the SuperFetch component;
- a large amount of computer trash.
The list contains only the main aspects, which will be further considered. And for situations when Svchost.exe is loading the processor in Windows 7, a solution for each specific case will be proposed precisely on the basis of what was the root cause of such an unpleasant situation. But first things first.
Windows 7: Svchost (netsvcs) loads the processor: a solution to quickly reduce the load
Many users quite rightly believe that reducing the load in the simplest case is possible by completing all the Svchost processes in the Task Manager. Yes, indeed, it can be done. But in this case, this is just a temporary measure (and if there are viruses, it does not help at all).
The same goes for a regular reboot of the operating system. After the restart, there will certainly be no increased consumption of resources, but the process itself in the form of four (at least) executable files in the Task Manager will still be present. This system component is automatically loaded with the system, and it is impossible to disable it using standard methods, say, using the startup menu.
System scan for viruses
But there are situations worse. Suppose in Windows 7 Svchost loads the processor. What should I do if a user sees ten and a half lines in the “Task Manager” with a link to the same executable file, and the CPU load reaches its maximum peak values?
Apparently, this is the first sign of a viral effect, since so many threats are masked just under the system process and are able to simultaneously launch several of their own copies. It will require manual user intervention with the launch of some powerful portable utility to deeply scan your computer for viruses.
It is best to use the Dr. Scanner. Web CureIt !, but the best option would be to boot from removable media with the Kaspersky Rescue Disk utility recorded on it. It is this program that is the undisputed leader, since it starts even before loading the OS, it can identify and neutralize threats that have deeply settled not only in the operating system, but also in RAM.
It is possible to determine that the selected process relates specifically to a virus threat by the additional attribute of the user name. There can be only two: either NETWORK SERVICE or LOCAL. If the user observes any other description, the conclusion is obvious: this is a virus disguised as an original process. In principle, before using antivirus utilities, you can use the PCM to look at the location directory of the accompanying process file and, if possible, delete it manually.
Troubleshoot System Update Issues
But viruses are far from always the reason that Svchost (netsvcs) loads the processor in Windows 7. Very often this is due to failures of the standalone installer of updates ("Update Center").
For example, some package was not downloaded at boot time. So it turns out that the system service is trying to load it (and the Svchost process corresponding to it is launched), but there is no result. On the other hand, the "Update Center" itself may for some reason not work correctly. It may require a restart.
In this case, the services section (services.msc) is called first, in which it is necessary to find the corresponding component, enter the editing section, stop the service and set the disabled startup type for it. After that, the system needs to be rebooted and the service activated again with an automatic start type.
Disabling or stopping related services
If none of the above helps, and in Windows 7 Svchost loads the processor, the solution can be reduced to see which processes are mapped to the executable file and disable them if possible.
To do this, the same “Task Manager” is used, in which through PCM on each process you need to look at the corresponding service, go to the main section and temporarily disable all processes, as was shown a little above.
Fix tunnel adapter issues
Infrequently, but sometimes there may also be non-standard situations associated with the operation of the so-called tunnel adapter. It is because of its malfunctioning in Windows 7 that Svchost loads the processor. The solution is to adjust its parameters or even completely disable it.
To do this, it is best to use the command console, called through the "Run" menu command cmd. Then, the lines shown in the image above are written to the console, and after they are completed, a complete reboot of the computer system is performed.
Cleaning system from debris
There is a simpler problem, but just as obsessive. If Svchost is loading the processor in Windows 7, the solution may be somehow related to computer garbage, for example, regarding the lack of free disk space for the normal functioning of the operating system itself (usually it is recommended to keep about 10% of the total volume free in the system partition )
First, you can clean the disk with a standard tool, if you turn to the section properties through the PCM menu in the "Explorer". On the other hand, some residual files after uninstalling programs in this way are not deleted. But finding them yourself is quite problematic. Alternatively, you can use special cleaner programs or optimizers (CCleaner, Advanced SystemCare, Glary Utilities, or something similar).
SuperFetch Issues
Another of the most common situations, many experts call problems with the SuperFetch service. To disable it, you can use the methods proposed above, with access to the services section, stopping the process and changing the type of start.
However, most often the problem is not even this, but the overflow of the corresponding Prefetch directory, which is located in the root of the system. It is because of it that in Windows 7 Svchost loads the processor. The solution is the simplest: delete the directory yourself, terminate all Svchost.exe processes in the "Task Manager" and reboot. After the restart, you do not need to reactivate the disabled service. For most users, it is, in general, completely unnecessary, and among other things, it is quite “gluttonous” in terms of consuming system resources, which on poor computer configurations leads to sad consequences.
If, in the “Task Manager”, a process is activated with the name of the executable file wuauclt.exe, you need to find the SoftwareDistribution directory (the OS root directory) and delete all subfolders and files from it, and then, as usual, restart the computer. You can also rename the original directory itself, giving it a name with the addition “.old” and reboot immediately even without deleting it.
Brief Summary
That's all that relates to the main reasons for the appearance of increased loads on the central processor and RAM, as well as the main methods for their elimination. True, in a certain sense, it is very difficult to say right away what triggered such a phenomenon. With certainty, this can be done only in case of a virus infection or in the case when even the manual update check or installation of updates does not work in the “Update Center”. In all other situations, you will have to perform each action individually. Except for possible failures or damage to iron (in particular, this applies to RAM strips), at least one technique, but will have a positive effect in any case.
Just in case, many experts recommend clearing the system event log in which LOG files are stored. It can be called through the "Run" console with the line eventvwr, after which use the cleanup items for the application, system, security and installation sections through RMB. At the end of all actions, the system must be rebooted without fail.
If the proposed methods for some reason do not work, identical actions can be performed in Safe Mode by pressing F8 at startup.
