Yep its in two places. C:/Program Files/Microsoft Office/root/vfs/ProgramFilesCommonX86/Microsoft Shared/Office16/Ai

And same type of path but replace X86 with X64

There will be ai.exe and aimgr.dll , if you remove those W11 runs much better.

Like I'd be working away not even active in an Office Product, and the systems would come to a halt with ai.exe as the resource hog
