I installed ccleaner and lo my pc did seem quicker but I soon realised my battery status icon had gone. I went to the power box off the start button but the box is unchecked and is grayed out so I can't tick it. Any ideas anyone please.
Can you please say what operating system you are using.
Also did you leave all settings at default?
Did you do a registry clean (issues) and if so did you make a backup when offered it?
