  • Hi Kapil,
    Have been trying to install KB4013429 in windows 10 Pro , OS version 1607 for the last three days and after eight unsuccessful tries, I have given up. Very irritating, it reaches 99% installing and would”nt complete the updates undoing changes and of course reverting to roll back the install of KB4013429.
    I have tried various troubleshooters including window 10 troubleshooter to no avail, so I decided to turn OFF
    windows update. No viruses or malware on the system.

    Any help to fix this problem would be much appreciated. Thanks. Nlthcn.

  • None of the cumulative updates, including KB4089848, has installed since the successful install of KB4053517. Hence, I am stuck on build 16299.125. I have tried all the fixes I can find on the web, short of using the media creation tool to do an in-place repair. Is this now the only option to get to the current build?

    ^^ Open administrative Command Prompt and type following commands one-by-one followed by Enter key.

    net stop wuauserv
    net stop cryptSvc
    net stop bits
    net stop msiserver
    Ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
    Ren C:\Windows\System32\catroot2 Catroot2.old
    net start wuauserv
    net start cryptSvc
    net start bits
    net start msiserver

    Close Command Prompt and see if Windows Updates works then.
