Microsoft has allowed users to install Windows 11 on older, unsupported hardware, moving away from its previous strict hardware requirements. Users can manually install the operating system, but devices that do not meet minimum requirements will not receive updates via Windows Update, requiring manual management of updates. A watermark will appear on the desktop, and a notification in Settings will indicate that the upgrade is not recommended. Microsoft will not lower the minimum hardware requirements for Windows 11, citing cybersecurity concerns. Unsupported devices will also be excluded from the Windows Insider Program. Users can revert to Windows 10 within ten days of the upgrade through the Settings menu.
