    If Windows 11 was installed on hardware that does not meet the minimum requirements, Microsoft recommends going back to Windows 10.

    If the upgrade to Windows 11 was recent, the simplest rollback method is:

    1. Open Settings > System > Recovery.
    2. Under Recovery options, select Go back if it is available.
    3. Follow the prompts to return to Windows 10.

    Important details:

    • The Go back option is usually available for only 10 days after upgrading to Windows 11.
    • Going back keeps personal files, but removes apps and drivers installed after the upgrade and any settings changes made after the upgrade.
    • To go back successfully, the windows.old and $windows.~bt folders must still be present.
    • If a password prompt appears during rollback, the Windows 10 sign-in password must be known.

    If Go back is not available, rollback to Windows 10 is no longer possible through Recovery. In that case, the supported information available here is only that the built-in rollback window has expired.

    For the TPM issue:

    1. Open Windows Security.
    2. Select Device security.
    3. Look for Security processor.
      • If it appears, the PC has a TPM.
      • If it does not appear, TPM might be disabled.
    4. Select Security processor details and check Specification version.
      • Windows 11 requires TPM 2.0.

    If TPM exists but is turned off, it can be enabled by following the device instructions for enabling TPM.

    If Windows Update is failing before downgrading, these supported troubleshooting steps can be tried first:

    1. Open Start > Settings > System > Troubleshoot > Other troubleshooters.
    2. Find Windows Update and select Run.
    3. If needed, open Command Prompt as administrator and run:
      • DISM.exe /Online /Cleanup-image /Restorehealth
      • sfc /scannow
    4. Try Windows Update again.

    Note: uninstalling security updates can reduce device protection, and a clean installation can remove apps or data if used later.

    Hi ,

    I'm Dyari. Thanks for reaching out.

    If you installed Windows 11 on unsupported computer and want to downgrade to Windows 10, you need to perform a clean install. but before that, please click Start > Type system information and hit enter >Screenshot and post it back to verify it before providing your with the clean install steps.
