First of all i was unable to configure my advanced power options, i.e- create new power plan, choose what power button does or closing lid does? I restored the settings & restarted but couldn't solve it. This is what i get while trying to fix this:- Somehow, then i thought of creating another admin account and config the settings there, to see if it works out. But, through Control Panel>User accounts i couldn't manage existing account and neither i am able to create new account. Another thing i noticed is when i go to PC settings through windows 8 new feature - charm menu, i couldn't find the Users menu. Now, these things are not normal at all. I have been googling hours for solution but no fix at all. So, i just hope to create new thread and seek for solution. Thanks in advance smart people. Plz HELP !!!
