    Going back to released Windows 11 depend on which build you have installed now.

    If you have build 28xxx or 29xxx then you have to do clean install of released version 25H2.

    If you have any 26xxx build then follow these steps:

    1). Download ISO for released version 25H2 https://www.microsoft.com/en-us/software-download/windows11?msockid=13c4190001016d9f341a0d8c008e6cab

    2). Delete WindowsSelfHost key from registry to get device out of insider program.

    Open regedit Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsSelfHost Right click WindowsSelfHost -key and select delete. Restart.

    The safest method that can keep personal files is an in-place upgrade/repair install using the current public Windows 11 ISO, as long as the Insider build is in the 26xxx range. If the device is on a 27xxx Canary build, the supported path in the provided guidance is a clean install, which removes apps, settings, and files unless backed up first.

    Recommended path:

    1. Back up important files first. Large OS changes can fail, and some install paths can erase data.
    2. Stop Insider enrollment on the device. Go to Settings > Windows Update > Windows Insider Program.
      • If available, turn on Unenroll this device when the next version of Windows releases.
      • If the device is still stuck receiving Insider builds, Microsoft Q&A guidance in the provided material says some users on 26xxx builds removed the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsSelfHost key, then restarted, before starting the repair install. Warning: editing the registry is risky; incorrect changes can cause system problems.
    3. Download the latest public Windows 11 ISO that matches the installed language.
    4. Mount the ISO and start Setup. In File Explorer, open the downloaded ISO, then run setup.exe.
    5. Choose the keep option that preserves data. For the non-destructive path described in the Q&A guidance, select Keep personal files and apps when prompted.
    6. Complete the installation and restart. This refreshes Windows with the public release while preserving data when the path is supported.

    Important limits from the provided guidance:

    • If switching channels, a clean install may be required.
    • If the build is already aligned with the public release, there may be nothing to roll back immediately.
    • If the device is on 27xxx Canary, the provided guidance says the option is a clean install.
    • A clean install using a Windows 11 ISO requires choosing Change what to keep > Nothing, and it erases files, settings, and applications.

    If the goal is specifically without losing personal files, the safest supported approach in the provided material is:

    • Use an in-place upgrade with the public Windows 11 ISO if the current Insider build supports moving back that way.
    • Do not use clean install unless backup is complete and data loss is acceptable.
