    Windows update causes 0XC000021A


    Hi, i built my PC back in august and have had no issues, until now.
    I got a windows update notification

    -updates
    "Cumulative Update for Windows 10 for x64-based Systems"
    "Update for Windows 10 for x64-based Systems (KB3106932)"

    as always i reset my PC when there's a windows update and when i do it cannot access the boot drive, so i proceed to go into the command prompt and input the "DISM /image:c:\ / cleanup-image /revertpendingactions" which puts me into the Deployment Image Servicing and Management tool

    i move the pending.xml and pending.old
    (via the "move C:\Windows\WinSxS\pending.xml C:\Windows\WinSxS\pending.old" command) the folders and it works until i restart my PC and it brings me back to the inaccessible boot drive window and i have to move the folders again.... is there a permanent fix for this? it's really annoying and i'm totally lost

    :)
