User/Pass gone....WTF?

[GoodChris]

I woke up this morning, and all of the sudden, the usernames and passwords that have always been stored on this machine are suddenly gone... I know its not cookies, because sites with form based login's still remember my info, but anything that pops the .htaccess style login is forgotten.

Anyone else seen or heard of this? Is it a virus or just another Microsoft fuckup?

It's happened to me before very odd

[GoodChris]

It appears that it was a Windows Security Update...

Fuck do I ever feel more secure now.
