I've been trying numerous times to upgrade my Acer Aspire R7-371T (aka R13) running Windows 8.1 to Windows 10, having read lots of articles about doing it. Yet every time I run the upgrade-in-place it barfs. Naturally I'm using the Media Creation Tool 21H1, and I've tried running it straight from the Internet and from an ISO file both. Everything goes fine until it gets 74% into the "Installing Windows 10" section and then it just aborts back to Windows with a simple dialog box saying "Windows 10 installation has failed". No error code or other message.
I've done all the preparations - made sure all the Windows 8.1 Updates are installed, uninstalled antivirus software, disabled all non-MS services in msconfig/services and Task Manager startup, remove Startup menu items, check my HDD (no errors or bad sectors), etc. I have plenty of disk space and detached all external devices (except Ethernet and mouse), and my Internet connection is solid. The "dism /online /cleanup-image /scanhealth" says that no component store corruption was detected, and "sfc /verifyonly" said it did not find any integrity violations.
Looking at \Windows\Logs\SetupDiag\setupdiagresults.xml, it's always the same Abrupt Downlevel Failure with a Failed to get the provider DISM Package Manager from the remote provider store error and code 0x80004005. File attached if interested.
I've googled like mad for this error, but haven't been able to come up with anything worthwhile. Lots of old articles from 2015, Windows XP, even Windows 10 Updates, but nothing about the upgrade from 8.1 to 10. Love to hear that I'm not the only one that's had this. Even better would be to find a real solution. After spending a week reloading another 8.1 laptop from scratch that crashed and wouldn't boot anymore (thanks to Windows Update) I'm ready to throw in the Windows towel and convert to Linux once and for all.
