I'm using windows 10 and updated automatically about two days ago.
I just realized that "Spooler SubSystem App" takes about 30% of my CPU time.
Restart does not work. (it's just there after reboot)
I don't have any printers.
Tried to close the spooler service but it's already closed.
Can not kill the process.
The process name is 'spoolsv.exe'
Memory usage is not high.
Googled it but couldn't find any solution.
Doe anybody know about this? please help. My CPU is burning for nothing.
