While Windows 11 checks for both POPCNT and SSE4.2, it does not actually need SSE4.2 for 99% of its files, with only a few exceptions that can be worked around (read on). To enforce this, Microsoft uses the undocumented RtlDetectProcessorFeatures function and checks for requirements by reading data from .rdata. In kernel 26100.7171, this is at offset 00000001400088C0 and has the bytes 01 00 00 00 00 00 00 00 00 00 10 00 02 00 00 00 0D 00 00 00 in IDA. To defeat this, we simply flip that 0D to a 0C, telling Windows to effectively skip the check and continue booting.<\/p>\n<p>Windows
