Can I install it on M1 Ipad?
QuoteMicrosoft may have been first to port its Windows operating system to Arm-based devices back in 2017,
That is actually incorrect, there was a Windows RT announced in 2011 and it was available on first Surface device in 2012 with ARM processor.
Btw according to Tihiy: x64 on ARM64 is not WOW64. There's no 64-bit registry, redirection, no x64 DLLs and WOW64 API won't detect it. Instead, 64-bit binaries are hybrid containing ARM64 and x64 code.
