Windows 7 Home Premium 64 bit
Windows 7 - SP 1 Install Error: Trust_E_NOSIGNATURE(0x800b0100)

Have tried unsuccessfully to install SP1 for Windows 7 x64 system on my PC on numerous occasions. Decided to try and solve problem once and for all and have scoured the forum which appears to have offered helpful advice to other people with similar difficulties.

I have downloaded and installed System Update Readiness Tool (KB947821) and I have run a SFC Scan - I hope that I have attached the relevant CBS logs.

I then tried yet again to install KB976932 and the installation stopped and showed the error code TRUST_E NOSIGNATURE(0x8006010).
