Solution to spoolsv.exe occupying 99% of CPUAuthor: jothui Date: I saw a good article on chedong's blog today. To tell the truth, I have never solved this problem before. I had to reinstall the system because I was in urgent need of a computer, this is not the case if you see it earlier.

Solution to spoolsv.exe occupying 99% of CPU> Chelong [blog ^ 2]
A few days ago, too many users encountered spoolsv.exe's CPU usage of 99%. I asked her to reinstall the operating system. I am too lazy to reload it, so I searched online: most of the articles on this issue disable the related printing background services, but in this way I cannot print it, isn't it a bit of a waste of food? Later 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.

Solution:
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.

 

Update:
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!

Postscript:
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.
