I have a Dell PC with Windows 7 Pro 32-bit.
I am NOT able to turn the Windows Firewall on or off.
Also, Windows 7 Firewall is not listed in Services.
My Network Location is set as "Work".
I can't turn on network discovery or File & printer sharing.
This prevents others from seeing shared folders or printers on this PC.
I have run sfc /scannow as administrator, but it stops at about 93%
The error message is: Windows Resource Protection could not complete the requested operation.
