Received an update last week. Ever since then, I lose my saved passwords for all websites that I had set to be saved after rebooting my system. This only started after this most recent update.
I ran into this problem and it was bothering me for weeks. Finally found a solution. Did not have to reformat my computer, or install windows fresh or anything, but I did have to create a new user account on the local machine, and then log into that account. Then in that new account, the problem doesn't happen anymore. Was kind of a pain, but way better than having to reformat.
Just FYI that's the fix.
