I've noticed that with almost every restart (not all) of Vista SP1 x86 that
certain programs lose their passwords: Outlook 2007, Windows Live Mail,
Skype, AIM, and one or two others (not IE).
Since Protected Storage is read-only in Vista, I take it that all these
programs use the newer Data Protection API.
Question: Why does this happen and what can be done about it? It's quite
annoying to have to re-enter all the passwords each time you boot, though as
long as I don't reboot the apps remember them perfectly (this isn't the old
"Outlook doesn't remember my password" problem).
I've seen some advice to delete the contents of this folder (there about 10
small files in it dating back over the last several months), but I'm not
sure it applies in this case.
