I have downloaded Windows defender offline on my system from the Microsoft website. My system is Dell which was upgraded to Windows 8 from Windows 7 about 6 months back. When I try to start Windows defender offline this is the error message that I get:
Windows Defender Offline cannot be started. Error: Unable to detect a Windows system drive. This could be due to missing drivers, and encrypted drive or a corrupted Windows installation. Error Code 0x8004cc01"
Can somebody help?
