What does TrustedInstaller.exe with 100% cpu load? RRS feed

  • Question

  • Every now and then my notebook becomes totally unresponsive, and usually it is due to a process called TrustedInstaller.exe that is hogging up all cpu.


    Can anyone tell me what this service is doing, or maybe even a way to stop this massive cpu load?

  • I used Sysinternals process explorer and process monitor to have a look on trustedinstaller.exe when it runs the cpu at 100%, and the process keeps on reading catalog files, I'd guess it is looking for something to install.

    But the process keeps opening the same files over and over again, a few hundred times before it finally stops hogging my cpu.


    Since this is happening after every reboot (and sometimes even just when the computer is running for a long time) I'd guess it is looking for a device driver for something, but I got no idea for what. Every hardware thing in my comp has a valid driver installed.


    Funny thing is, this only happens on my notebook (Samsung X20), not on my desktop.


    Anyone got any ideas about this?
