The initial problem is, suddenly my Windows 7 64-bit Ultimate is reported not genuine. However, it is purchased from Microsoft few years ago. The error code is 0xC8000247. After reading some Microsoft forum, it is suggested that the system may be corrupted, and they suggest me to use System File Checker ( sfc ) multiple times.

After I run sfc /scannow in elevated Command Prompt (the logged in user is Administrator) twice, a CBS.log is generated. By using the following command:

C:\Users\MyUserName>findstr /c:"[SR]" %windir%\Logs\CBS\CBS.log >"%userprofil
e%\Desktop\sfcdetails.txt"

Then a sfcdetails.txt is generated on my desktop. Here is the key lines:

2013-08-25 00:27:05, Error CSI 0000006b (F) [SR] Component not found: Microsoft-Windows-Security-SPP-UX, Version = 6.1.7600.16385, pA = PROCESSOR_ARCHITECTURE_AMD64 (9), Culture neutral, VersionScope = 1 nonSxS,

Also, the forum suggests that I run the following commands in a batch file, in Clean Boot mode:

net stop wuauserv 
ren %windir%\SoftwareDistribution\WuRedir WRold
ren %windir%\SoftwareDistribution\DataStore DSold
ren %windir%\SoftwareDistribution\Download Dold
ren %windir%\SoftwareDistribution\SelfUpdate SUold
net start wuauserv

After rebooting to Normal Mode, the problem persists. Windows Update still fails & it is told my Windows is not genuine.

Also, they suggest me to execute REGSVR32 WINTRUST.DLL and the response is succeeded. Still fail.

What should I do next to fix these issues?

  • Your installation appears corrupt beyond the ability to repair it.

  • Microsoft didn't cause your installation to become corrupt. Critical system files are corrupt this is normally caused by a hdd that is about to fail.

You need to repair Windows 7 by doing an Inplace upgrade.

  • Insert a Windows 7 DVD into your drive (or mount an ISO)
  • Run setup.exe from the DVD inside Windows
  • select Upgrade and follow the setup.

  • Already tried. After loading for a while after click Upgrade. The upgrade said, "Installation has failed". Then I rollback.
