I wish! There were a few important changes to the system starting last
Friday and I dearly wish I could go back to before those changes.

On Friday, I accidentally installed OpenCandy, a PUP adware "program". I
spent some time on Saturday cleaning that with a host of free malware
removals. This removed some registry keys, but I'm pretty sure it was
all safe. Pretty sure...

Also on Saturday I replaced two old HDDs with SSDs. This made my system
a lot faster, but I haven't seen any problems associated with it aside
from the OS complaining about not getting a network connection right
after it boots. I think this is just because it boots so much faster now.

I /should/ have tested the snapshots when the call went out. I wished I
did now, because then I would know if this issue was related to any of
the problems I had late last week. This is a work machine and we're
super-busy, so I was hesitant to experiment with snapshots. But I
learned my lesson; I'll be testing snapshots when Chris or Corinna ask
for testing from now on, on all my machines.
