In Windows 10, Microsoft Software Protection Platform Service is using more than 30% of my cpu. I tried the things listed here:

https://ugetfix.com/ask/how-to-fix-high-cpu-usage-by-sppsvc-exe-on-windows-10/

The first 2 don't work and when I disable it with the 3rd method the cpu usage problem goes away, but a message is displayed in the corner of my screen in gray text saying "Activate Windows Go to Settings to activate Windows" that displays on top of everything else and never goes away. Is there anything I can do other than reinstalling Windows?

If you tried the regedit solution, make sure to get the Start value in
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\sppsvc set to its previous value (2 instead of 4) so Windows and other Microsoft products can get back to normal.


The only alternative solution i found is :

  1. download processHacker,install and run it
  2. look for sppsvc.exe (you can use the search bar)
  3. right click on the process and click suspend.
  4. Optional:quit process hacker.

You should suspend it every startup,unless you found out a way to automate this. UPDATE : suspending sppsvc.exe will cause Office to crash often.

Any method to disable sppsvc will also deactivate all your microsoft products including windows. If you suspend the service, (you can do that with resource monitor. No need for a third party software) the high cpu problem will be resolved but MS Office will hang after a few minutes as it tries to do a validation request to the suspended service.

Contrary to the windows activation process, until MSO receives a positive response from the service, it will wait for an answer, while windows will just postpone the validation for a later time.

So here's the current situation, as of december 31st 2018 : Suspending the service is a good workaround if you need the CPU power for a game. Once you are done, you can re-enable it and use MS Office or anything else that doesnt need intense CPU process.

This is the only workaround that i know of, as i searched for a solution for the last 9 months daily.
