Great - now please run another SFC /SCANNOW and post the CBS log - correcting the manifests may change the results.

SFC /SCANNOW finds no error and see attached CBS logs.

Thanks again.

There;s a couple of minor errors in the SoftwareDistribution folder -
Code:
 Line 505: 2013-01-21 21:58:32, Error                 CBS    Failed to verify if catalog file \\?\C:\Windows\SoftwareDistribution\Download\81e30664749127d4842fd5cce29ad467\update.cat is valid. [HRESULT = 0x800b0100 - TRUST_E_NOSIGNATURE]
 Line 3295: 2013-01-21 22:06:33, Error                 CBS    Failed to verify if catalog file \\?\C:\Windows\SoftwareDistribution\Download\65acc9d714229a053d74cf2446d2a6f0\update.cat is valid. [HRESULT = 0x800b0100 - TRUST_E_NOSIGNATURE]

I'd try installing SP1 offline, now - download it from here... Download Windows 7 and Windows Server 2008 R2 Service Pack 1 (KB976932) from Official Microsoft Download Center

It should clear the SD folder anyhow as it installs.

Hi Noel,

SP1 was already installed successfully with last fix you had provided but two critical updates were failing with error you have mentioned in SoftwareDistribution folder.

I deleted all content from SoftwareDistribution folder and rechecked for updates then I was able to install those updates too.

Thanks for your help.

Kind Regards
