    TPM = Trusted Platform Module (<> Trusted Protected Module).

    Typically you could also go into MSConfig if there is more than one boot entry for the OS as well. Then set default or clear if you are scared of command line.

    [01:22] - What is FSAVAILUX in System32?

    Zippy should run xperf to see what the process is doing and why it hogs the CPU:


    [19:20] - User gets a window created by DWM.

    the user never replied so I have no idea if he fixed it.


    [21:45] - New computer won't sleep, how to debug.

    I would run POWERCFG /DEVICEQUERY wake_armed and powercfg -lastwake instead. This shows you which devices cause the PC to resume again.

    I managed to solve my problem meaning I was able to check the problematic harddisk (no errors found) and the Action center's message doesn't show up anymore. But I can still reproduce it. Weird thing is that this harddrive only contains non-active VHD, hyper-v's xml files and ISO files.

    My pc has a main SSD and 2 normal HD's. I tried to do a manual checkdisk (from the drive's properties window) with each of them and 1 of the normal HD's also caused checkdisk to go into the CPU hogging mode (no sign of the fsavailux process but taskmanager showed a COM process hogging it).

    I'm 100% sure there was NO drive activity during the 100% CPU hogging process. Taskmanager and resource manager didn't show any activity and I couldn't hear the drive rambling and certainly not for more than 15 hours (total cpu time reported by taskmanager).

    EDIT: screenshot made with Process Explorer. I created a memory dump too, if anyone is interested let me know how you want to receive it (30 MB zipped).

    run xperf and upload the zipped ETL file.

    Here it is. The drive is an internal SATA drive, no USB.

    @ZippyV: The dllhost.exe that is running hot is a chkdsk thread. All of the modules are MSFT - not much you can do without a change from us.

    @windev: But what's going on here? Why is the CPU being hogged while there is no disk activity?
