Heavy CPU Load by TiWorker.exe and mscorsvw.exe RRS feed

  • Question

  • Hi.

    The TiWorker.exe and mscorsvw.exe loads my CPU to 50 % on Windows 8 64-bit. I install KB2771431 Update but I still suffer from heavy load. 

    As for mscorsvw.exe. I use "ngen.exe executequeueditems" command but problem persist.

  • Hi,

    The process known as Windows Modules Installer Worker belongs to software Microsoft Windows Operating System by Microsoft.

    Please try to use command below to fix this problem for test:

    DISM /Online /cleanup-image /RestoreHealth

  • Given the time between when you last posted and today, I would imagine that it is likely, but have you simply allowed it to run and do whatever it is doing in the background? It was discovered in this thread that TiWorker.exe was simply doing what it was intended to do, clean up the WinSxS folder. This also helped to resolve this thread with the same issue.

    If the issue has persisted for an inordinate amount of time or seems to be using performance and is not performing expected tasks, another thing that you could try which appears to have helped resolve some users’ issues is to stop and restart the Superfetch service.

  • The big problem is TiWorker.exe.

    The mscorsvw.exe stops, for now to overload my CPU, but TiWorker still overloads

  • That command didn't help. It's still overloads.

    I also try sfc /scannow command, but with no result.
