Win7Prof Error while Updating to SP1: TRUST_E_NOSIGNATURE(0x800B0100)
Just installed successfully Win 7 Prof on a Lenovo notebook but get an error while installing the SP1 (KB976932). I've tried with the integrated update routine and the stand alone package with the same result.
As I looked around and researched for a while, it seems to me that the only solution might be to use your help by following your steps :)
1. I executed Windows6.1-KB947821-v33-x86, the System Update Readiness Tool (SURT).
2. I ran the SFC Scan who didn't found any problems.
3. The Windows Update error code is 800B0100.
4. Attachment 334914
