Was unable to apply the update by restarting normally. Tried twice. Then
it applied itself when I selected Restart from within Windows Update.

It reset all of my fonts.

My Macrium Reflect backup size went from 19 GB to 30 GB.

After my mouse has been idle, about 10 processes open in rapid
succession upon moving the mouse, followed by one process closing (could
be all of them closing it once, I dunno). That one seems kinda weird.
