What does each error and each result mean?

[isfrito]

I would like to know and I know that many also what some error codes mean.

I put these examples:
Error Code: 0xC004C008 phone activation.
Error Code: 0xC004C060 has expired.

But what do these mean?

if I check it here it gives me this error:

Key: RC2MV-NWWDR-RPTF2-9K622-DDBP6
Description: Win 10 RTM Professional Retail
Error code: ..is activated with a product key
Time: 2/6/2021 12:11:38 AM (GMT+7)

but if I check it here it gives me this:

https://key.aihao.cc/key.php?key=RC2MV-NWWDR-RPTF2-9K622-DDBP6.png&t=1612540299060.png

and others say: Online Key

Can someone please help with that question?
