At least once a week I have to go into settings and change it to Not Require a Password on Wakeup. For some reason this setting keeps getting randomly changed to require a password. I have experienced this on my desktop as well as my laptop. Both are new systems and both are running Windows 7 Ultimate x64.
No one else has had this happen? Just today it's done it twice on my laptop and once on my desktop.
Well I would look at third-party programs first...
Can use Process Monitor
But no, never happens here, Windows is not going to change settings without help.
Do you have it unchecked in both the power settings and screensaver settings ?
There is also 1 more action you can try.
Click start, type netplwiz. Then in the user accounts click users tab and make sure user requires a password is unchecked.
