Microsoft has revised its guidelines for installing Windows 11 on devices that don’t meet the operating system’s minimum requirements. The company no longer recommends using unsupported hardware, citing risks of compatibility issues and potential disqualification from security patches. Users installing Windows 11 on unapproved systems will receive a watermark and notifications about unmet requirements. A rollback option to Windows 10 is available for 10 days after installation. Microsoft has not specified the reasoning behind this change, but its market share shift may be a factor.
