Hello all

My wife and I had an account each on our desktop PC which allowed each of us to sign in at start-up.

There was no password and we were both administrators.

After upgrading to Windows 10, both of our accounts exist on C drive and we can switch between them, however the system automatically signs in to whoever was last on the computer. The lock screen does not appear, although sometimes I think I see it for a millisecond. I only know the lock screen exists by manually switching between accounts.

I have accessed the Advanced User Control Panel and the only users are myself and my wife with administrator privileges, nothing else.

Please help as this is a frustrating problem for an otherwise decent update.
