Windows 10: PC will not start shows blue error code 0xc000021a, and then eventually starts and Window...

PC repeatedly will not start Windows 10, screen shows a blue error code 0xc000021a then shuts down. After repeated restarting attempts eventually shows a pink screen message 'We couldn't complete the updates. Undoing changes. Don't turn off computer.', then windows 10 starts.


I suspect Windows 10 Updates is the problem, as when I try 'Windows Update' I get the message Your device is missing important security and quality fixes' with 'There were some problems installing updates.....0x80080005'.


I am running: Window 10 Home. Version 1903, Installed on 04/10/2019, OS build.

Any solutions please?






I have run the windows troubleshooter for the update feature, but it has not resolved the windows update issue.


I'm using win10 pro, version1703, build 15063.608
