@showmethefacts, it might be worth summarizing:
- What updates are showing persistent errors in Windows Update? Sometimes errors are transient or are due to a required reboot and the update eventually installs.
- Are any updates repeatedly installing even though Windows Updates claimed the install was successful?
- Other than the error codes, are there other problem symptoms associated with specific updates?
- What steps you have taken to try and resolve the problems?
If the Windows Update component update store is corrupted, then it is important to get DISM working. I recall you were getting errors trying to run Dism /Online /Cleanup-Image /RestoreHealth from an admin prompt and also running sfc /scannow from an Admin prompt. If these commands do not run, you may have more fundamental issues that I hope Robert's suggestions will help resolve.
