    Did this just start? Any triggering events? Windows Updates recently? Installed any new programs? Do you have several programs running in a compatibility mode? FYI, you have 6 more processes running in that area of task manager than I so here's mine for comparison:

    I also use the latest Start8 without issues so I guess that's not the culprit. BTW, is there any chance you are using Avast 2014 (Avast 9)?

    If no issues are found, then some OS corruption may exist. To address that issue, please run through the following tutorial and see if that helps:

    DISM - Fixing Component Store Corruption in Windows 8

    Note: In Option 1, step 2, you can skip the first 3 input messages and just input the 4th directly.

    Let us know.

    Did that fix your original problem?
