They usually have the same name or one of the following names: spoolsv.exe, spoolsu.exe, spoolsv0.exe, spoolso.exe, SP00LSV.EXE (please notice that there are zeroes in this file name, not letters) and some others. Please note that legal spoolsv.exe should reside in Windows\System32 folder and should not appear in startup list.

What is spoolsv.exe?

A Microsoft Windows file stored in the c:\windows\system32 or c:\winnt\system32 directory that has the file description: Spooler SubSystem App. This file is responsible for how Microsoft Windows handles print and fax jobs on your computer.

The spoolsv.exe is using 99%, 100%, or other high amount of CPU.

When the spoolsv.exe is using 99% to 100% of the CPU it is caused when there are still printer jobs in the Windows spool. To manually remove these print jobs follow the steps below.

  1. Open the Control Panel.
  2. In the Control Panel double-click the Administrative Tools and then Services.
  3. Within services locate Print Spooler and right-click it and select Stop.
  4. Once this process has been stopped leave the windows open and open My Computer and browse the below folder.

c:\windows\system32\spool\PRINTERS
or
c:\winnt\system32\spool\PRINTERS

  1. In this folder delete all the files in the PRINTERS folder. Once these have been deleted you can right-click the Print Spooler in the Services window and click Start to re-enable the service.

If this does not resolve your issue it’s likely you have an issue with your printer drivers you have installed for your printers or you have a trojan, virus, or worm infected on the computer. Make sure you have the latest printer drivers for your printer. A listing of printer drivers can be found through our printer drivers page. Additionally, make sure you have an antivirus protection program on the computer and that it is up-to-date.
