I've read where 20H2 eventually shows up again.and subsequently fails again. The problem being, when I run Windows Update, it want's to install 20h2 but FAILS! Then it won't show up in the Windows Update screen, instead I have the green checkbox like everything has been installed but I don't get that warm fuzzy feeling that this PC is properly updated. I've been brought here because I have 1903 installed from a factory restore PC. I've confirmed that all the links above point to the same download 'Windows10Upgrade9252.exe (5.9MB)'.assuming that will also try to download the current version, 21H1.
