C windows system32 spoolsv exe что это

One of Microsoft’s services is the spooler subsystem application that is embedded into Windows OS. The primary function of the Spooler Subsystem App application is to print and fax the tasks that are sent to the PC’s Printer or Print Server. This process is also responsible for printer configuration, which means if the service is disabled, then you can’t see the list of installed printers.

Is spoolsv.exe a virus?

Malware programs such as viruses, Trojan, and worms deliberately give their process the same file name to escape detection, but spoolve.exe is not a virus by itself.  However, if the antivirus is flagging spoolsv.exe, it is primarily because of a virus that has corrupted it. This corrupted spoolsv.exe file can be identified and detected by simple & almost any antivirus program. The user should never delete or remove this file, so the best way to save this file is you use an Up-to-Date antivirus program to detect the viruses and clean or quarantine this file if infected.

Most of the time, such processes do not use much of your computer’s resources. Although it will use some CPU resources when printing, and that’s a regular thing. Some people are reporting that there is high CPU usage by the spoolsv.exe process, but it rarely happens or happens when there is a problem somewhere in the windows printing system. When the spoolve.exe process uses 99% to 100% of the CPU, then possible problems might include buggy printer drivers or utilities, a print queue full of jobs, or a misconfigured printer, failing to execute the process, the system may start lagging.
