Window7Ultimate error

I use Window 7 Ultimate-64bits in my laptop.It didn't work normally yesterday.It doesn't allow indexing and rate.All driver has been installed.Please help me.

Where did you get Windows Ultimate and how is it activated?

What do you mean you installed drivers? Win7 is driver-complete in the installer and when you run all rounds of Important and Optional Updates, after enabling Automatically deliver drivers via Windows Update (Step 3).

If you provided a bunch of drivers Win7 didn't ask for before giving it a chance to provide them, then I suggest you start over and do it correctly. Clean Reinstall - Factory OEM Windows 7

My problem is as the as the link(Youtube) https://www.youtube.com/watch?v=dU8pxnm9GJw
But it can't be solve the way in above link.Please help me.I use Driver Pack Solution(DPS 2013)

Did you run the registry hack shown in the video? If so see if there is a System Restore point from before this so you can go back before the problem began.

If not run a full Malwarebytes scan and SFC /SCANNOW Command
