Hi. I could not found help about this on google. I'm unable to change settings in two different situations: 1. The option to disable hybrid sleep in the power profile is unavailable. It says "some settings are managed by your system administrator" . 2. Some options in IE's delete browsing history are also greyed out. Again "some settings are managed by your system administrator" . Creating new user account (with admin rights) doesn't work. Also, it's not the Group Policy (all the GP settings are at default). It would be helpful if someone knows the registry settings for permissions for power management and internet explorer's policy settings.
