    Windows 8 enterprise x64


    This 920 should have no problem running Windows 8 , why 8 GB RAM, you should have 3, 6 , 12, 24 GB , how many stick you have ? if you are using 4 sticks, you loose a certain speed. I wait your reply to explain more

    It's a Dell XPS Studio, it's the way it came and has worked flawlessly with Windows 7. It was also working flawlessly with Windows 8, until the updates.

    Are you sure the CPU heatsink are clean, if a CPU overheat , it will reduce the speed to compensate for the heat

    Only cleaned the entire system recently. But also, Windows 7 works fine and is faster at opening applications than Windows 8 on the same machine, yet before the update, Windows 8 was faster.

    Can you look into the Windows Update history as to what the last Windows update was before your PC started to slow down? Try removing that or the other updates around that time Windows 8 started to crap down. This seems like it would be the best shot.

    By the way, what as the date too you started to experience this?

    The update happened on 14 Nov. Apparently, these were critical updates (some 44 of them), so removing them is going to be a right pain.

    Of which, what are Windows updates? I'm looking at my update history and I have nine updates for Windows, no Office as I have Office 2013 RTM evaluation running.

    There were 30 updates to Office 2010 and 14 updates to Windows, at least on my Gigabyte tablet. My PC is pretty much a duplicate of my PC, but the tablet is x32 and the PC x64. Something is amiss with the x64 updates.

    I believe the update is tied to TiWorker.exe which is part of Windows Modules Installer Worker

    I was having this problem of the system just pounding on the CPU, I was working on a Rainmeter Skin that I thought was causing the issue.

    I just did "Remove everything and reinstall windows" had it wipe the drive that windows is installed on
    When it finished reloading, i installed all current updates (approx. 530M or so, can't remember).

    But it seems for now the issue is resolved. I do believe this was caused by a Windows Update, but not sure which one.

    It seems to be fine for now, will report back if the issue starts again.

    I have also reinstalled Rainmeter 2.4 final with my Layout (a.k.a. Skin) and ClassicShell, along with other modifications I had also done previously, to see if the issues return.

    This is on a Dell Inspiron 1764

    Sorry for all the edits... I also remember seeing Service host: Local Service (Network Restricted) using a ton of CPU as well.
    Not sure which part of that might have also been causing issues, or be related to TiWorker.exe

    There is definitely something wrong with KB2770917. I opened Windows 8 again this morning and the update was again there, but a different size this time, so I gave it another go and it failed once more. Why would this update go from something around 150MB, into two smaller updates, one of which succeeded and the other which does not?

    I really don't want to remove any of the successful updates until this issue is resolved, as the updates will keep popping up again, and this failing update may have a bearing on the OS performance.
