I just want this one simple question answered because I can't find it in any Internet searches.

What is Windows 10 Update Error Code 0xc1420121?

Maybe if I knew I could finally upgrade my machine from Insider build 18908.

Please don't respond with "try these ten thousand items". They don't work.

Just tell me what Error Code 0xc1420121 means! Something must be causing it and if I knew I might be able to rectify it.

If looking at my log file helps I can supply it.

But just answer the question, please.

Thanks.
