Thanks for the reply. I tried disabling automatic restart, but it
didn't change anything, so that didn't help.
Even after uninstalling TortoiseSVN, it didn't change anything. I had to
revert to a previous restore point after booting Last Known Good
Config, and that finally got me back to a working computer.

I guess I'll just have to wait for a software update and try it again.
Thanks again.
