So since Microsoft claimed that Windows 10 was compatible with the newer of the bedroom computers and the apps installed there, I figured I'd go ahead and run the upgrade from Windows 7. It looked like everything ran fine.
Right up until Katie tried to run Minecraft. Minecraft won't run, because the default driver that Microsoft installs for this old Intel chipset doesn't support OpenGL. There is no Intel driver for Windows 10 and the older drivers won't install.
So I figured I'd uninstall Windows 10 and revert back to Windows 7.
Except that option is missing.
I've tried telling it to go back to an older version via a different restore path, but the computer has been sitting there for hours now saying "Restarting".
Thanks, Microsoft, for making my little girl cry.
"Compatible". I do not think that word means what you think it does.
