    Win 10 version 20H2 installing stops at 87% installing


    This update has frozen at Status Installing 87% for over 3 hours. Any suggestions? Should i wait or try trouble shooter? feels like it should not take this long.

    Win 10 Home version 1909 OS build 18363.1440 installed on 29/07/2020

    Please keep answer pretty non tech for this "oldie"!

    You're right: it shouldn't take that long. You can let it run overnight if you're patient, just to make SURE it's not going to finish on its own. That said, are you working from an online download or a local ISO file? If you're not using an ISO that might be your next best bet. If that doesn't work, then you can start troubleshooting. You can visit the Download Windows 10 page and follow the instructions to use the Media Creation Tool (MCT) to build installation media.

    Hi there
    Agree


    I remember when doing a complete full "SYSGEN" on some old IBM Mainframe systems - circa mid 1980's -- MVS / SP for example never took more than a couple of hours --and that was on hardware today that even a lowish laptop would run rings round (For old timers - some of the hardware was on old IBM 3031 / 3033 equivalent boxes).

    Also a lot of modules on that "Sysgen" would have to be compiled "in line" from source -- using the IBM built in Assembler and actually a good "Meta language "they had at the time called PL/S --note NOT PL/1 which was quite a good language anyway.

    IBM PL/S - Wikipedia

    MVS - Wikipedia

    If A simple windows upgrade is taking that long --something mega wrong somewhere.

    (For those who want to try running an older IBM Mainframe OS on a PC --yes it can be done surprisingly easily !!)

    Here you are -- start with the Hercules emualtor and follow these lonks --yes it really works on Windows (and Linux) too.

    As EdTittel commented please allow it to run overnight (complete vs rollback).
    Typically failed upgrades create files that can be troubleshooted.
    Run setupdiag: https://docs.microsoft.com/en-us/win...rade/setupdiag > post a share link using one drive, drop box, or google drive

    Any reason for reinstalling Win 10?
    Is your HDD healthy?

    Left it overnight and it finally completed, that meant it took at least 14 hours to finish.

    Now it gives a further complication, all the colours are screwed up and despite trying every combination I cannot get back to what I had - a black background to the taskbar, with a white start icon, and a tab/address bar with a pale blue blue background. Any idea how to get back to what I desire not what Microsoft think I want? Neither dark or light mode helps.

    If it took 14 hours to finish, something is wrong.
    I suspect you may have a failing drive. Backup your data.

    There is a default 10 day rollback period.
    This can be modified to 60 days but must be modified before day 10.
    At day 11 the Windows.old can be automatically deleted preventing the rollback.

    Also a rollback can fail during the default 10 day default rollback period.

    So it is always best to make free backup images.

    Thanks for clarifying.
    Is it the Asus with i5 4200U/4210U Processor?
