Thanks for the reply. I ran a system restore to an earlier point. It didn't work out.

System restore did not complete successfully. Error 0x8000ffff

An unspecified error occured during system restore.

I tried it again this time using a different restore point. All the same.


How do i restore my security settings to default settings? Is there any other way?

Even command prompt is disabled. Access is denied.

Try Startup Repair a few times, from Disk.

If it fails enable BuiltIn Admin from Disk Command Line, see if you can get in to create and transfer over to a new Admin account, hide Built-In again.

If these fail you can rescue files and try the other steps in tutorial below, leading up to if necessary the perfect reinstall specified.

Built-in Administrator - Enable from WinRE
I'd use the Win7 Disk or Repair CD System Recovery Options Command Line. The F8 Repair console may be corrupted too.

Then User Account - Create an Admin account. Try running your programs under it and if it works move your files and confirm all programs run from it before deleting the old account.

You can also try repairing the old account but it saves time to just move to a new working one. Either way I'd run SFC /SCANNOW Command - System File Checker to know if you have corrupt System files. If so you can attempt to repair them as given in tutorial, or even try a Repair Install.

But keep in mind that if you're still running the factory install that is the worst install of Win7 one can have, larded with bloatware and duplicate factory utilities that interfere with better versions built into Win7. You'll never even experience Win7 performance on that PC until you do what most tech enthusiasts do to Clean Reinstall - Factory OEM Windows 7
