    I totally agree with all these statements. I think after major updates it takes the PC some time to sort everything out after the required restart.

    Well, 3 hours in all to install and run a clean-up. Disk space despite disk clean-up showing only 250mb to remove has settled at some 600mb down (the OS space used) from just before the update was started. Disk clean in the end recovered some 2gb back. A defrag from a command prompt showed some 4% fragmentation, so a lot has changed.

    Just to satisfy my curiosity I uninstalled avast through add remove programs rebooted then ran avast clear to get rid of the remnants rebooted again. Windows Defender enabled itself. Ran the update again from the installer I had previously downloaded rather then through Windows Update.

    Exactly same scenario.....the update will not complete the install and just backs itself out after rebooting itself twice so it's definitely not avast causing the problem in my case.

    I've now definitely given up on this update.

    For the curious: I made a list of all the files (1729 in total) that were modified by KB3000850 on my system.

    EDIT: probably what I should say is that these were all the system files that changed after that update.
    Some of them may have changed for other reasons, but I minimized that likelihood as much as possible.

    Interesting, that's quite a list. Thanks

    (my first shutdown took longer than normal, and my first "boot" from shut down took around 17 seconds compared to the usual 13 or so. Percentage wise, that's a big hit, hope it recovers with use)

    Most of the files in System32 folder seems to be affected according to that

    It appears it is looking for the update on F: drive. Don't know if it is a virtual drive the update process creates or problem with actual drive assignment.
