    Spooler subsystem app and high CPU usage


    Before sending this, I have Googled the issue and have had no success; this, I am turning here for help.


    Recently I have had high CPU usage on my Toshiba Laptop, Windows 10, all latest updates installed. On checking, I found that it was the spooler subsystem that is using 26-29% CPU. I have tried all of the fixes that I could find and the problem persists. 1 For example, I ran the Printer Troubleshooter, and it returned no errors. 2 I checked to ensure that I have the latest drivers installed and I do. The printer HP ENVY 5055 prints with no problems. 3 I stopped the spooler in Administrative Services and then tried to delete any cached print jobs at C:\Windows\System32\spool\PRINTERS. There were no jobs there.


    Does anyone have any ideas as to what else may be wrong?


    Thanks for any help.

    :)

    Spooler SubSystem app

    Hi DaveM121,

    I have done what you posted a number of times. The first time there a file in

    " C:\windows\system32\spool\PRINTERS" and I deleted it. But since then everytime I go throu these steps there is no file in this folder.

    After I go thru the steps you list the Spooler SubSystem app is not active and my CPU usage is low. But the next time that I print anything on the HP OfficeJet Pro 8715 the Spooler SubSystem app starts to utilize more then 50% of the CPU again. This cycle
    happens over and over. I was looking for a more permanent solution.

    Thanks for your time. Don B.

    Spooler SubSystem app is consuming too much of the CPU

    Hello Sarah Kong

    Thank you for your reply, I have carried out the steps as you suggested and all appears to be working correctly . The Spooler SubSystem does not now take over the CPU. Thank you.
