    revert to Windows 19041 from 20H2, possible? how?


    Without my permission, Windows 10 spontaneously updated to 20H2 two days ago. Anyway to revert to the previous version, which I believe is 19041 or whatever the latest version before 20H2?

    Two days ago, when I turned on this desktop PC, which I use maybe once or twice a week, it went through some setup menu and asked me to enter an email address. Without thinking, I entered a hotmail address and, alas, I created a Microsoft account, which I had always been trying to avoid.

    I have searched the net to figure out how to remove the Microsoft account and use local account. All the articles I have found say there is an option called "sign in with a local account instead". Well, all PCs and laptops I own don't have that option. I do see a "Manage my Microsoft account" option but it's gray out. I followed this link (2 Ways to Disable or Block Microsoft Account in Windows 10/8) and changed the registry value of NoConnectedUser to 3. It didn't work.

    The account I am working on is the default Administrator account. Maybe this account is so special that it's missing some options. I don't know. I don't think I can nor want to delete this account.

    So, the only option, besides reinstalling Windows, seems to be somehow revert to the previous version of Windows. Possible? In the Settings/Windows Update/View update history/Uninstall updates, I don't see the option to remove 20H2 because the last updates installed was in May. There is nothing in June.

    Hello @yky378,

    Your best option, if you create System Images, is to Re-Image to the LAST System Image. The impact will be minimal as you only use the computer a couple of times a week. If you have made ANY important changes to Files for example, copy them to a USB BEFORE Re-Imaging.

    You might also find this useful . . .

    I hope this helps.

    You gave MS your permission by acquiring a Home license.

    That said, for years ways of controlling updates have been published- for free. So you could have taken control had you wished to stay on a given build.

    Tutorials are available.

    b. Note that by default 'Go back to the previous build' is available for 10 days, extendable to 60 (tutorial available).

    After that the only way, unless you created a disk image of your system disk with the previous build would be to do a clean install. (The routine use of disk imaging is endlessly recommended here).

    Thank you for the reply. I tried the delete user profile method in the post #62 and it worked. I lost the old profile, which was 14.5 Gb in size. Hope there was nothing important in it. I backup files in the download folder before deleting the profile.


    In the future, use backup software. It's by far your best friend in the Windows 10 universe.
    Personally, I use Macrium Reflect, as do most of the regulars on here.

    With a full OS image backup, you can try anything. If you break Windows, all you need do is restore from a backup.

    With Macrium's Rescue Media (bootable), you can access your backups even if Windows won't boot.
    It's like a "Get out of jail free card".

    Thank you for the reply. I tried the "delete user profile" method in post #62 and it worked. My old profile was 14.5 GB in size. I had backup files in the download and documents folders before deleting the profile. Hope nothing important was missing.

    Thank you for the reply. Since the method in post #2 worked, I didn't try the method you kindly provided. Hope that's OK.

    Thank you for the reply. I have to admit that I hardly read any license agreement.

    You should always have a fairly recent "full OS image backup". Aka, a backup of the 3 or 4 partitions, C:\ included, that you need to boot into Windows.

    After that... make whatever other backups you think necessary. But make sure you have one FULL backup...
