I found this article on a foreign website: Tim's journal: spoolsv.exe hogging 99% of CPU-the fix

The solution is actually very simple. Suppose you have used anti-virus software to exclude viruses and anti-spyware to eliminate the impact of malware:

Just clear all the files in the C:/Windows/system32/spool/Printers directory.

The cause is also documented on the Microsoft Website: The Windows Background print program does not delete the background file of the print job. As a result, the print program may repeatedly attempt to process the print job in the background.

To avoid this problem, do not change its properties when the printed background file is in the % SystemRoot %/system32/spool/Printers folder.


To solve this problem, delete the read-only attribute and delete the background file from the % SystemRoot %/system32/spool/Printers folder.

To delete a read-only attribute, right-click windows resource manager or a background file on my computer, click Properties, click the clear read-only check box, and then click OK.

For more information about how to delete files in Windows 2000, click Start, click Help, click the Index tab, type delete, and double-click Delete file topic.


According to flyingrufei, another method to solve the problem of repeated spoolsv occurs: The printer has a background management option to control. Open the spoolsv service (in my computer --- manage ---- service --- print spool, start), open the printer project on the control panel, right-click the printer properties --- advanced, change Background printing to direct printing --- OK!

Promotion: there should be many similar problems. If you find this method useful, please

During a chat with jianshuo, I learned from Wendy, who is also working at Microsoft: this problem actually exists since Windows 2000, but it has not been solved by XP. Microsoft also has related help documents, but it is a pity that users cannot find them online, because there is no description about spoolsv accounting for 100% of CPU, so: the idea between developers and users is simply two different things.
