If you find that your laptop is slowing down to crawl without change and your CPU usage increases to a high level of 100%, you should review the Windows processes running on your computer. One of them, vssvc.exe is also known to cause high disk or CPU usage.
The.exe extension of a file name displays an executable file. Executable files can be malware in some cases, and malware is known to take the names of other legitimate files. In this case, you must first search and find the vssvc.exe file by starting the search. If it is in the System32 folder and its properties indicate that it is a Microsoft Volume Shadow Copy Service file , then this is Microsoft’s legitimate process. But if it is in another folder, it may be malware.

Shadow Copy Volume service manages and implements Shadow Copy Volume copies for backup and other purposes. If this service is stopped, hidden copies are not available for backup and backup may fail. If this service is disabled, not all services that explicitly depend on it are started. VSS helps you backup your system drive. Disabling this service may also cause some applications to lose functionality.
Volume Shadow Copy Service (VSS) usually does not consume many resources, but if you encounter problems with vssvc.exe, try these suggestions.

You can do this via Control Panel > System > System > System Protection.

If you are not using System Restore or Volume Shadow Copy, you can disable this service.
