Windows XP, Vista, 7, 8/8.1, and 10 are affected by this issue. This is a legitimate Windows operating system file that runs inside Windows. However, some people mistakenly think that it is a virus because of its name. In fact, the spoolsv.exefile is part of the Windows Operating System. So, if you see spoolsv.exe running in Task Manager, do not panic. There is nothing wrong with it.
If the spoolsv. exe process is located in the "C:System32" folder, then it is not a threat. But, if it is located somewhere else, it might be a malicious program. You need to check whether there is something suspicious running on your computer.
