    Hello @Dan McDermott

    The reason Windows Update is trying to push 25H2 even though you’re already on 26H2 comes down Cache files that may have been stored on the device.

    The way to stop that is by resetting the update components so Windows doesn’t keep retrying the wrong feature update Open Command Prompt (Admin) Windows + X and search for Command Prompt and select Run as admin.

    Run these one by one:

    cmd

    :: 1. Stop update services
    net stop wuauserv
    net stop bits
    net stop cryptsvc
    
    :: 2. Rename update cache folders
    ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
    ren C:\Windows\System32\catroot2 catroot2.old
    
    :: 3. Create a system restore point
    wmic.exe shadowcopy call create Volume='C:\'
    
    :: 4. Restart services
    net start wuauserv
    net start bits
    net start cryptsvc
    

    After this reset, check Windows Update again Or restart the device.

    Hope this helps.

    Sounds like this is dangerous to do. Is it?

    Hi Dan,

    Unenrolling doesn't automatically

    remove you from the Insider Program

    until the next Feature Update is released

    in Oct.

    Try deleting this Registry Key and then

    restart the PC. This should remove you

    from the Insider Channel you have selected.

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsSelfHost

    Hi Dan,

    Right click Start, click Run and type in

    regedit, click OK. Follow this path to the

    correct key

    When you get to the Windows SelfHost key right click and Delete

    User's image

    Then close Regedit and Restart the PC.

    there is a lot of stuff in there
