Thanks, Micael, though I hadn't read about the Windows 10 problems. But Windows 8.1 gave my nice, powerful desktop such a lobotomy that I figure even new, 10 can't be worse. Our review in the San Jose Mercury News said that anyone with Windows 8 / 8.1 should go ahead and upgrade. I actually tried that. I installed two smaller updates, which both succeeded, and the only one left was the big 8.1 Update. That not only failed - it rolled back the smaller updates as well! :-( Bob

It will not be better in Windows 10 - the update-problems continues... And you may have read all about other problems with the Windows 10. Are there many updates, you can't install? Then Try this In Windows Update Click on Change settings - set it to "check for updates but let me choose wether to download and install them" Unmark them all Take them in smaller groups - e.g. 4 - 5 updates, the smallest of them, get them installed, restart and go for the next 4 - 5 updates, again the smallest of them, and so on, until there isn't anymore updates to get

Running Windows 8.1 on a 1.5-year-old 64-bit desktop with 8GB of RAM (plenty). For the last 6 months it has been attempting to install Windows updates, rebooting, getting to the 99% complete stage during the purple post-reboot screen, then saying "Unable to complete updates" and rolling them all back - taking up to 8 hours to do so, during which my system is unusable. When this happens, it wipes out the update history, so I can't find an error code to use in diagnosing the resolving the problem. It says I've never attempted any updates! I've been waiting eagerly for Windows 10 hoping it would solve my problem, but now I can't apply the Windows 8.1 Update that is supposed to be my migration path to Windows 10. Is it possible to upgrade directly to Windows 10? If not, how can I get this damn 8.1 Update to install when it not only won't tell me what failed, but tells me I never even tried to apply it?

I followed these steps however, when I go to view update history, it shows NEVER on the update history. So, how do I correct this and, is it an 8.1 issue? Maybe I should go back to Windows 8 where everything worked? Tony Ciavarra

@ Pabitra See what you can get from that link I found? Although it says W7 I think it still applies (mostly, at least analogously) to W8.1 too. Good luck Robert
