Thanks.
Windows 8.1 has successfully reinstalled itself, and it isn't corrupted - yay - so I'm installing Windows 10 now though the Media Creation tool.

I didn't get asked for a key, and it says...

I'm very sorry. I did look, but obviously not hard enough.



That's great. Thanks very much for taking the time to answer my question.

As well as that, will I have to install other updates before I install 10?

Hi,

Because my current Windows installation seems to have issues that are beyond fixing...
