Windows 8.1 - high-ish CPU usage when idle caused by various system processes

    Question

  • Hey all. So I upgraded to 8.1 from 7 and I faced this issue where I have the same exact programs opened that I had back on windows 7, but now they are generating alot more CPU usage. I can't find any solution to this, other than installing 7. That fixes it. On win 7 with the same exact enviroment (same programs opened, same page on google chrome opened, same exact everything) I get 1-4% cpu usage which is great. On win 8.1 however, with again everything the same, I get 18-30% cpu usage.

    And it's all caused by windows' processes and stuff. Can't really shut them down because things won't work then.

    I kinda like win 8.1 so I don't wanna go back to 7, but since my performance is crippled, I might have to. Any suggestions are much appreciated! I've tried some things that I found on the internet, but nothing seems to fix it.

    A friend of mine has the same mobo and cpu as me, but when I did a test and created the same exact enviroment as on my pc, the usage doesn't go above 5% when idle.

    I dunno what to do at this point.

    Here's some screenshots of my task manager:

    On this last one you can notice that there's a misterious difference between the user cpu usage and the overall, idk what causes that.

    I tried doing clean install and have absolutely nothing installed and it still stays at around 15%

  • This is related to TiWorker.exe which is part of windows update.  YOu may be downloading the setup files for win 10 in the background or it may be something else.

    I would start by running a system file check and the troubleshooter.

    Please run a system file check (SFC) & DISM  if you are on win 8 or higher

    All instructions are in our Wiki article below...
