I run W7 Pro Sp1 64 bits. My Windows Update ultility had not worked since Sep, 2014. I attemped to resolve this by running the MS Fixit utility ( http://support.microsoft.com/kb/971058
) and SFC /scannow as administrator. Some updated downloaded but most failed.
I then restores my OS and software to its state in Aug 2014 using the Lenovo Rescue and Recovery utilty. Windows Update now runs, then asks me to restart, after the restart it has not however installed any updates. Please see attached two screenshots.
All suggestions gratefully received.
