WINDOWS 10 Experts Please

Last week my New HP Desktop computer AGAIN installed an all to frequent update.. I have the computer set up to when turned on to start without entering a password. After the last update, 2 out of every 3 times when turned on, the computer prompts the wife for a password which we don't have.. I then have to turn the computer off for about 30 seconds and restart it again and it starts/signs on without entering a password and works fine. Not a pleasant experience for the DW or me who she summons every time it does this. Anyone else experienced this problem, and if so.. what corrective action did you take?
