The company allows manual installation on older hardware but warns of security risks, lack of updates, and visible warnings.

Microsoft now officially allows Windows 11 to be installed on devices that do not meet its minimum hardware requirements, including lacking TPM 2.0.
Unsupported systems will not receive automatic updates, including critical security patches, and users must install updates manually if needed.
Devices with unsupported hardware will display a desktop watermark and a notification in Settings, warning users of compatibility issues.
Microsoft advises against using Windows 11 on unsupported hardware due to potential performance, stability, and security vulnerabilities.
Users who upgrade to Windows 11 on unsupported devices can revert to Windows 10 within 10 days, with Windows 10 support ending in October 2025.
