The problem started when I wanted to install these two updates, when it gets to 8%, I get a notification saying, my pc doesn't meet requirement for windows 11, but when I use pc health check and whynotwin11, they say it is compatible, secure boot status was off, I turned it on...the TPM status is "maintenance task is still running"...so I've been trying to make it say "ready for use", then I discovered regedit is not opening, I've been trying ways to open it, in order to try and change the TPM's status and hopefully then the updates can go through...I'm scared to have to install another window and possibly lose all my data, I've been avoiding that...these are all step I have been following on Youtube...I don't know anything about any of this

Hi,

If the PC Health Check tool indicates the system is compatible with Windows 11, but the upgrade is blocked, there may be hard blocks in place.

Please share a zipped copy of the following setup log file on OneDrive (or any other host) and post the link here:

C:\$WINDOWS.~BT\Sources\Panther\setupact.log

Note: C:\$WINDOWS.~BT is a hidden folder. To access it, press Win + R, type C:\$WINDOWS.~BT and click OK.

    Since PC Health Check shows compatibility but Windows Update stops at 8% with a requirements message, the fastest supported path is:

    1. Back up personal files first.
    2. Make sure Secure Boot remains enabled.
    3. Install any pending Windows updates first.
    4. Temporarily uninstall or disable third-party antivirus/security software if present, because it can interfere with upgrades.
    5. Disconnect nonessential external devices.
    6. Use the official Windows 11 installation tool for the upgrade instead of waiting for Windows Update to refresh its compatibility status.

    Before trying the upgrade again, run these built-in repair steps:

    1. Open Start > Settings > System > Troubleshoot > Other troubleshooters.
    2. Find Windows Update and select Run.
    3. If the issue continues, open Command Prompt as administrator and run:
      • DISM.exe /Online /Cleanup-image /Restorehealth
      • Wait for the success message.
      • sfc /scannow
      • Wait until verification reaches 100%.
    4. Try Windows Update again.

    If Windows Update still fails, use the official clean installation/installation tool page:

    Important:

    • Avoid random Registry edits from videos. Incorrect registry changes can cause system instability or data loss.
    • A clean installation is not the first step here.
    • If any Start replacement app is installed, such as StartIsBack++ or Stardock Start10, uninstall it or update it first. Those apps can trigger a Windows 11 compatibility hold.
    • If the upgrade screen shows What needs your attention, update, uninstall automatically, or manually uninstall the incompatible app, then select Refresh.

    If the update is stuck at a percentage, also check:

    • Restart the PC.
    • Confirm the internet connection is stable.
    • Make sure there is enough free disk space: at least 16 GB for 32-bit OS or 20 GB for 64-bit OS.

    For advanced repair only if comfortable using admin command line, Windows also provides a reset of Windows Update components:

    1. Open Command Prompt as administrator.
    2. Run these commands one at a time:
      • net stop bits
      • net stop wuauserv
      • ren %systemroot%\softwaredistribution softwaredistribution.bak
      • ren %systemroot%\system32\catroot2 catroot2.bak
      • net start bits
      • net start wuauserv
    3. Restart the PC.

    A clean install should only be considered after these supported steps, because it is more disruptive.
