Windows update has stopped working and I need help diagnosing and correcting the problem. The "Cumulative Update for Windows 10 Version 1607 for x64-based Systems (KB4013429)" failed to install on 3/17/2017 and that is the last update attempted. There have been no updates applied in almost a year. When I attempt to manually download and install that update (KB4013429), I get an error saying it is not for this maching, although I am running Windows 10 x64.
The Windows Update Troubleshooter (run as Adminstrator) does not correct the problem. It starts to run, stops and asks "One troubleshooting step to resolve WU issues is to delete and re-load updates to your computer. would you like to try this step now?" I "apply this fix", it runs to completion, reports a few errors found, and states all have been fixed. However, Windows Update does not identify and needed updates since the last one on 3/17/2017.
Any suggestions on what to try next?
