Spoolsv.exe and 99% CPU
If the printing service (spoolsv.exe) is using 99% of the CPU, and an reboot of the whole server and or just the service does not work, what could be wrong?
Maybe an old print-job is stuck on the computer.
Go to: C:\WINDOWS\system32\spool\PRINTERS
and remove all the files.
Restart the printing service.
