@moderate Oh wowzers, I still have my old Surface RT with Windows 10 ARM 1793 (15035.0) and was following your experiment back then very closely...and yay, it just booted up ! Seeing this thread beeing alive, would that mean I could now update my 1793 (15035.0) ? ;D Asking because of post #642 WUMgr v1-1-2b (AnyCPU DotNET v4-x) Did you also experiment with Windows 11 on the RT ? Where would I best start reading again ? Holy Moly !
