Upgrading to Windows 10...
I've had one of my computers on Windows 7 for a long time, but it was really time to wipe it and reinstall so I figured I'd do that to while upgrading it to Windows 10.
Wow, what a mistake that was.
Few things I ran into:
If you plug the monitor into the video card instead of the onboard video (in other words, if you hook it up correctly), the fresh Windows 10 install doesn't create proper bootable partitions. Seriously.
I eventually decided I should install Win7 and upgrade instead, anyway, to get things Win10 removed from 7 like a DVD decoder. So I didn't fully solve the above.
Windows 7 had a similar issue with the onboard video, but it actually installed correctly in the end.
Windows update doesn't work the first time unless you let it happen on the schedule (which would only fire off 24 hours after the initial time I set). Activating it manually hangs forever. Microsoft's Windows Update fixer and tricks like stopping the update service did nothing. After 24 hours it finally installed 250 updates (I hoped I'd avoid some of that by downloading the latest ISO from Microsoft, but nope).
The Windows 10 upgrade procedure also hangs forever when it checks for updates. The fix turns out to be stopping the Windows Update service when the upgrade checks for updates.
The Win10 upgrade starts over and re-downloads the entire upgrade if it is stopped for any reason.
The automated upgrade that pops up and asks to upgrade is much, much slower than using Microsoft's Media Creation Tool to do it manually. Like many hours for the background download instead of a few minutes for the manual one, on my 175ish Mb/s connection.
After the Win10 upgrade completes it reboots, gives an error code and says there was an unknown SAFE_OS error, then reverts to Windows 7 again.
One whole weekend wasted.
I don't care enough about Windows 10 to put up with this shit. At this point the only thing keeping me going is my engineer brain that can't stand unsolved puzzles, but that brain needs to get back to work.
But I'll be fair, this is the fifth machine I've upgraded, and the first to have so many problems (others had little issues but not like this). That's why I wasn't worried about putting it off until the last second. If I feel motivated this week maybe I'll try and figure it out. Maybe a BIOS update might help, or something like that. But it's looking pretty likely my kids' computer will stay on Windows 7.
