What is Spooler SubSystem App? – Using So Much CPU

The Spooler SubSystem App it process is named Spooler SubSystem App, and the underlying file is named spoolsv.exe. It’s responsible for managing to print and faxing jobs in Windows.

When you print something, the print job, it sent to the print spooler, responsible for handing it off to the Printer. Suppose the Printer is offline or busy. Also, the print spooler service holds onto the print job and waits until the Printer is available before handing it off.

It process also handles other interactions with your printers, including printer configuration. You can not it able to see your list of installed printers if you disable it. You need it to process if you want to print or fax things on your Windows PC.

Why is it Using So Much CPU?

Also, the process should typically not use many of your computer’s resources. It uses some CPU resources when printing, and that’s normal.

In some cases, people report high CPU usage by the spoolsv.exe process. It’s likely due to a problem somewhere in the Windows printing system. And possible issues can include a print queue full of jobs, buggy printer drivers or utilities, or a misconfigured printer.

In this situation, we recommend running the Windows printing troubleshooter. And on Windows 10, head to Settings > Update & security > Troubleshoot and run the Printer troubleshooter.

And on Windows 7, you’ll find the Printer troubleshooter under Control Panel > System and Security > Find and Fix Problems. It attempts to find and fix problems related to printing automatically.

If the printing troubleshooter can not discover and fix the problem, find your list of installed printers. Also on Windows 10, head to Settings > Devices > Printers & scanners. Also, On Windows 7, head to Control Panel > Hardware and Sound > Devices and Printers.

Open each Printer’s queue by clicking the Printer and clicking “Open queue” on Windows 10 or double-clicking the printer on Windows 7.

If there are any print jobs you did not need in any of the printers, right-click them and select “Cancel.” You can click Printer > Cancel All Documents in a print queue window.
