• IsarcExtract works on Windows 11 (x64, ARM64) without requiring additional compatibility tweaks.
• Run as Administrator if files require system-level access during extraction (e.g., extracting into C:\Windows\Temp).
• For Windows 11 updates that use .psf + .cab pairs (common in newer cumulative updates), IsarcExtract will extract the .cab, but applying the .psf delta requires additional tools like psfextract or DISM.
