Why can't I run Sfc/Scannow as admin when I am the admin?

Hi,

I have the same problem and trying to follow these steps but i dont see anything on the top left to right click at. Is there any other way to run as admin through the cmd?

Btw, mine is windows 8.

Just what I was looking for, 

Straight, simple and to the point

Thanks!

Found it! thanks anyway!

A Clean Boot for Explorer

It might be caused by a shell extension.

Explorer (explorer.exe) is the program that is the Start menu and taskbar, folder windows, and the desktop (which is a folder window).

Explorer is built on addin programs called Shell Extensions. The standard ones are supplied by Microsoft but programs add their own.

• Download Autoruns from http://technet.microsoft.com/en-us/sysinternals/bb963902.aspx
• Close any Explorer windows
• Start Autoruns by right clicking and choose Run As Administrator
• Click Options menu - Filter Options and tick Hide Microsoft entries and clear Include Empty Locations
• Go to the Explorer tab and untick everything left.
• Click Start. Ctrl + Shift + Right click a blank spot (just above the power buttons is one place) then Exit Explorer.
• Press Ctrl + Alt + Delete and choose Task Manager.  Check all explorer processes are closed. On the Process tab select explorer and right click and choose End Process, repeat if more than one explorer in the list.
• Click the File menu then New Task (Run) and type explorer

If it helps, reenable ½ at a time to identify which one. If it doesn't help, restart AutoRuns and go to the Everything tab and untick everything there and reboot. If it helps, reenable ½ at a time to identify which one.
