In my testing, updates for the current point-releases (i.e., builds 22000.71, 22000.100, etc.) will install without issue on top of previous 22000-based versions of Windows 11.On some systems, Windows 11 may be unable to enter sleep mode, or have other driver-related issues.While I have personally tested the third method on a computer with a Legacy boot system (i.e., no Secure Boot), some computers may simply not be able to run Windows 11.While they don’t seem to be as strict as the ones in the eligibility checker or an ISO, they may still prevent you from installing Windows 11 through Windows Update. The first two methods will still perform requirements checks on your device.There’s no 32-bit build of Windows 11 available, so only computers with 64-bit processors will be able to run Windows 11.Note: These methods can’t bypass every requirement, and your unofficial Windows 11 install may not work properly.
