Thank you for helping me, it is very appreciated. I ran the Windows Update Reset tool given in the link above and it worked for a while, then told me it had fixed a few issues. I closed it and ran Windows Update again. it took a while to check the system, and then gave me one important update to run - the same update that's causing the problems. Unfortunately, the same error occurred and I've attached a snapshot.
I guess you didn't need me to run SFC again for info. as I've already provided. Do you have any ideas on how to help further please!?
