how long does this last? should I just let it go? there's so many sticked threads here it is very confusing. I downloaded the latest ISO (or it was the latest a few days ago) and now I'm running the setup.exe from a windows 8.1 enterprise trying to upgrade to 10 enterprise. stuck at 67-68 for now 1 hour 13 minutes. HD light blinking but not solid. if it wipes my data I will be pissed. have no room for backups. edit: I did the same overnight from an 8.0 and it worked but I don't know how long it took. these are older machines that will need a intel 965 fix that I hope will be on Windows Update. edit: they are both offline at the moment. so this has to do with 8.0 and 8.1 activations that WERE online, but now they aren't. if that matters. I still have to do a Win 7 but that will be later. edit: made to 69% on the 8.1. 1 hour 39 minutes. edit: it sucks fooling around with win 8.0. win 8.1, win 7, win 10, win server 2019, and Apple iOS whatever it is update all at the same time. + android edit: plus I'm doing an offline XP install for someone which is easy that is just HP disc edit: bumped to 78%. 1 hour 46 minutes edit: 78 and counting to 87. why do they bother with percentages? how do they calculate them?
