Hello. I was on build 29580 and updated my hardware (motherboard ram and cpu). Everything went ok and I managed to boot the same windows installation on the new system without problems. But when the next build 29585 appeared on windows update installation failed with a boot loop. Then I decided to make a clean install with the official iso 29585. But when I finish the installation all the choose your insider settings are grayed out. I tried all the known fixes but nothing seems to work. I tried then the new iso for build 29591 as an upgrade and as a clean install but the same thing happens. How can I get back the option to be on  canary channel and receive the latest builds from windows update?

Hi it seems that i've found the solution. The first thing i did is what @CrazyKats told me but it did not work

Try deleting this Registry Key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsSelfHost

After that i tried the following and after restart the latest build (ver. 29595) installed with no problems

  1. Press Win + R, type regedit, and hit Enter.
  2. Navigate to the following two paths:
    • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsSelfHost\Applicability
    • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsSelfHost\UI\Selection
  3. Look for the string values named BranchName (in Applicability) and UIBranch (in Selection).
  4. If they are set to anything else, double-click them and change their value data to CanaryChannel.
  5. Reboot your PC and check for updates again.

    For devices on the Canary 29500 series builds (including 29580, 29585, 29591), leaving or rejoining that channel cannot be done just by toggling Insider settings after a clean install. For this series, the documented path to change off the channel or repair issues is a clean install, and Insider settings can be restricted or unavailable on some of these experimental builds.

    Key points from the current guidance:

    1. Canary 29500 series builds are early, unstable platform builds and are treated differently from other channels. Some features and options may change, be removed, or never ship, and documentation can be limited.
    2. To get off the Canary 29500 series channel, a clean install of Windows 11 is required using a non‑Insider (production) image.
    3. If the goal is to continue receiving Experimental/Future Platforms (formerly Canary 29500 series) builds, the supported methods are:
      • Install a supported Insider Preview build from an Insider ISO and then confirm Insider settings under Settings > Windows Update > Windows Insider Program.
      • If Insider options remain unavailable or greyed out after a clean install of these experimental builds, this is a limitation/behavior of the channel itself rather than something that can be fixed with a registry or settings change.

    Given the current behavior:

    • To move to stable Windows and then re-enroll in an Insider channel that exposes configurable Insider settings, perform a clean install of a production Windows 11 build using the official Windows 11 installation media, then join the Windows Insider Program again from that stable build.
    • If remaining on the Experimental (Future Platforms)/Canary 29500 series is required and the Insider UI is greyed out even after clean installs of 29585 and 29591, there is no documented supported workaround beyond reinstalling Windows from a stable (non‑Insider) image and reconfiguring Insider participation from there.

    For any scenario where Insider builds are stuck, unstable, or not updating correctly, the official fallback is a clean installation using an ISO (either Insider or production), backing up data first because this will erase files, settings, and apps.

    Hi,

    I had that on a PC about a week ago.

    One of the Repairs I tried to do messed

    something up. I ended up using the MCT, ran the setup

    from withing the folder and kept nothing. I was then

    able to rejoin Insiders and update to Canary.
