Solved Error 800B0100 when trying to install Windows 7 Service Pack 1

[youngmk]

I have tried multiple ways to resolve this problem (System Update Readiness Tool, SFC scan, Microsoft Fix it, manual installation, etc.) but to no avail.

When I try to install the Windows 7 Service Pack 1 for x64-based Systems (KB976932) via Windows Update, the installation fails with an error code 800B0100.

When I tried to manually install the SP, an error message appeared with details: "trust_e_nosignature (0x800b0100)."

I am pretty frustrated considering the number of unsuccessful attempts and time I've thrown into fixing this problem. So, hoping that it will be addressed here, I have attached my CheckSUR log. Please let me know if any more information is needed.

I'll post a fix protocol for them later - in the meantime, please run an SFC /SCANNOW, and post the CBS.log so we can see if anymore files need fixing as well.

Here is the compressed CBS folder containing the CBS log.

Good - the SFC scan is clear, at least.
There are however a large number of errors related to the attempt to install SP1 - I hope most of them will go away after the fix I'll be posting in a few minutes.

 

[NoelDP]

I've uploaded a file - ymkaa.zip - to my SkyDrive at Noel's SkyDrive
Please download and save it.
Right-click on the downloaded file, and select Extract all…
Extract to the default location - which will create a new folder ymkaa in the same place.
Open this folder - there should be two folders inside it (Manifests, and Packages)

Copy the content of the Packages folder to the folder
C:\Windows\Temp\CheckSur\Servicing\Packages

And the content of the manifests folder (.manifest files) into this folder:

C:\Windows\Temp\CheckSur\Winsxs\Manifests

Now run the CheckSUR tool again (it may take a while)

Post the new CheckSUR.log file, and the CheckSUR.persist.log file.

Once completed, please also run another SFC /SCANNOW and post the new CBS.log file so we can see if this has highlighted any new problems.

 

[youngmk]

I've attached the updated CBS folder containing the new CheckSUR and CBS logs.

UPDATE: Windows Update successfully installed the Service Pack! Thank you so much, Noel. I am so glad that I decided to post my problem here on SevenForums.

Inferring that the Service Pack installed without any problems, I will mark this thread as solved. Once again, thank you.

 

[NoelDP]

Yep - all seems good now - and the fact that SP1 installed is a good sign

Good luck.
