I may have gotten Katie's computer working again with a bare metal reinstall of Windows 10. The number of little glitches in this version is dismaying. The Wi-Fi kept cutting out on this box -- not on the identical one that Gretchen and Julie use -- for reasons that appear to be subject to any number of voodoo solutions. One of them seems to have worked.

Of course, I spent some time before applying a voodoo solution to get Windows 10 to stop thrashing my hard disk on my computer in the last two days, so...

I understand that there are some difficulties in getting an OS to run on a variety of hardware choices. Even so, this is just being exceptional.

And not in a good way.
