I recently had to restore my system OS disk from Acronis True Image 2015 backup. Once I've done that, everything was 99% peachy, except that my OS keeps asking for my MS account PW each time I login. I always auto-login and so I went and set it up again, but it didn't help. I still keep being asked what my password is... Why is that? Do you think the backup-restore process messed something up? Everything else seems to work just fine...
I forgot to say that once in a while, it loads my desktop without asking for password, but 4 out of 5 times it does ask me for one.
