Unable to install Security updates - error codes 0x8000400, 0x8024402C
Good evening
Since the beginning of January 2017 The monthly security updates refuse to install. I get error codes 0x8000400 and 0x8024402C. The updates get to between 93 and 98 percent then fail and a rollback occurs. When I eventually get back into Windows the update manager tells me that I have an update to install which is always the one that fails. I have only managed on two occassions to get the update to install.
I have downloaded and run the Hotfix file (Windows6.1-KB947821-v34-x64) numerous times. I have downloaded and run the Windows Diagnostic Update Troubleshooter tool numerous times. It alsways finds and fixes the same errors but it does not fix this error - 0x8024402C. I have run the 'sfc /scannow' command which does not find any errors. I also tried running the wu170509 troubleshhoter program but it will not run.
I have done a search on the internet and followed the advice in these links (there are other links that I have tried). The first one took me over two hours to do. Sadly none of them have resolved this issue.

Microsoft Update Catalog
All my other updates install. I have followed your procedure for update bugs. The CBS zip file is 48MB in size. I have uploaded the file and some other files to my DropBox folder. This is the link to it:

I have seen that there are a number of tools available for solving 0x8000400. All of them find a ton of stuff to fix including the registry. I do not like tools that modify the registry willynilly. I also do not want to purchase a whole load of tools and then find that they do not fix my issue.
All the Microsoft people on the Microsoft forum say this issue is due to malware and viruses. Well I have a good anti-virus program which updates automatically and does scans automatically. todate it has found no malware or viruses.
I am rather concerned about this issue and I am hoping someone may be able to assist me to resolve it.
I am running Windows 7 Ultimate 64 bit. I ran dxdiag and I have uploaed the result file to DropBox.
