    Upgrading to 21H1


    OS windows10 20H2 (19042.1826)

    I want to use the enablement package for 21H1
    A) Is this the one I should download from the catalog?
    2021-05 Cumulative Update for Windows 10 Version 20H2 for x64-based Systems (KB5003173)

    According to Control Panel>Installed Updates
    Servicing Stack 10.0.19041.1790
    B) Do I need to download another one? If so then which one:

    2020-09 Servicing Stack Update for Windows 10 Version 2004 for x64-based Systems (KB4577266)

    Or
    2021-01 Servicing Stack Update for Windows 10 Version 20H2 for x64-based Systems (KB4598481)

    P.S. I got this one installed via windows update after resetting windows

    2022-07 Cumulative Update for Windows 10 Version 20H2 for x64-based Systems (KB5015807)

    on its page it says:

    If your devices do not have the May 11, 2021 (KB5003173) or later LCU, you must install the special standalone August 10, 2021 SSU (KB5005260) before installing this update.

    It's way over my head!


    Many thanks in advance.

    The easiest way is to just do an In-Place Upgrade. It will repair any Windows issues, get you up to date and leave your programs and files untouched.







    Repair Install Windows 10 with an In-place Upgrade



    Here is the short version of the In-place upgrade tutorial...

    DISABLE non-Microsoft:
    a) antivirus software
    b) firewall software
    c) drive encryption software

    Make a full OS backup with a program like Macrium Reflect (free)
    Macrium Software | Macrium Reflect Free

    Go here and get the Media Creation Tool and save it to your desktop.
    https://www.microsoft.com/en-us/soft...load/windows10

    RUN the Media Creation Tool and use it to: Create an ISO image... save IT to your desktop.
    This will be the latest version of the ISO image.
    The ISO must be created in the same language as you are using in Windows, to be able to keep your Programs and Files.




    Right click the ISO image and choose: MOUNT
    Open File Explorer and you will see a new drive letter. It will "look" like a DVD optical drive.
    Double click the new drive letter to open it.
    Find setup.exe and double click it to start the in-place upgrade.

    Choose the Keep personal files and apps option.

    After it's all done... to UNmount the ISO image, right click the new drive letter and choose: EJECT.


    The ONLY thing you will lose is some of your personalizations. Your programs and data will be intact.

    I see that. I had trouble going from 1909 to 2004, and this was on a clean install (of 1909), pretty much.
    An In-Place Upgrade took care of it easily.

    Sometimes In-Place upgrade is just easier, as was mentioned here...
    21H1, 21H2 are still missing



    At least the In-Place Upgrade takes care of all the prerequisites.
    I also like my little copy/paste of the "short version". I think it takes the "scary" out of the tutorial.

    On that thread, the links were for 21H2 but I want the previous version, 21H1.

    Thanks for the short version but for a computer illiterate, all is creepy. BTW, Is the desktop file executed offline? or online?

    Someone on the house didn't want to wait and used update assistant which started that infamous defender error 0x2. We had to do the online in- place upgrade and it took the defender back to 1999 never been run, something like that. Turned google upside down for solutions and there was none but some old update in 2018.

    So maybe if I upgraded to 21H1 it would get sorted out.

    My advice to you is to do an In-Place Upgrade to 21H2.
