How to bypass Windows 11 requirements for old devices

Replacing `appraiserres.dll` is an ISO modification method that can be used to bypass Windows 11 requirements 2026; this is done by replacing the compatibility check file with the corresponding file from a Windows 10 ISO, but it disables the hardware validation tool built into the Windows 11 installer. This workaround does not work on the latest Windows 11 24H2 and later versions.

Step 1: Download the Windows 11 ISO file and extract all its contents to a local folder.
