What is vssvc.exe? Vssvc.exe High Disk Usage Problem and Solution

Manages and implements “Volume Shadow Copies” used for “Volume Shadow Copy Service Backup” and other purposes. If this service is stopped, shadow copies are not available for backup and backup may fail. If this service is disabled, any service that explicitly depends on it will not be able to start. VSS helps back up your system drive. Also, disabling this Service may lose the functionality of some applications.

High Disk Usage Issue

Without making any changes, you may observe that your computer slows down and your CPU usage exceeds a high figure of up to 100%. One of the processes running on your Windows computer, the “vssvc.exe” process, is known to cause Disk or CPU usage.

The .exe extension in the filename indicates 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, the first thing you need to do is search and locate “vssvc.exe” using Search from the Start menu.
