It always bugs me when Windows does an update and I find that it has changed my power options settings. This does not happen all the time - but maybe as much as 50%.
For example, it likes to change my setting for:
Put the computer to sleep: from 20 minutes (or whatever) to Never
However the most annoying offender is under Advanced Settings, changing
/Balanced/Require password on wakeup/Setting: No - to Yes.
Then I have to dig down 4 layers to reset it to No.
I am using Win7 Ultimate 64-bit, but I see it on other systems running other versions of Win7.
Is there a way to prevent this? Changing a registry setting is perfectly acceptable for me.
