Windows 10 Activation (Insider)

I did a full clean install of Windows 10 a while back and it will not activate. I didn't do a clean install from Windows 7/8/8.1 it was from Windows 10 (activated) so I expected it to activate just fine since it was fine before hand.

My Windows 10 license wasn't created from a previous Windows 7/8/8.1 key I got it from signing up to be an insider back in Nov of 2014. I installed a preview build on my laptop from the insider program and it worked just fine and it automatically upgraded to newer and newer preview builds and then to the full release automatically, fully activated and working fine. I did a full clean install not long ago (expect it to go through without issue since it was working before) and now it will not activate and I can't find any info on how to get it to activate and I can't seem to find the insider Windows 10 key.

Microsoft online support was useless and the gave me the toll free number to tech support.. I am currently on the phone waiting, they said it could be a 1hr 30min wait.. sigh.. Any help would be appreciated. Thanks.

 

Windows 10 activation question

do the upgrade
it should activate automatically when online
if you want todo a clean install after that simply boot from your windows 10 installation media and when prompted for a key during install/post install select skip ..
it will re-activate within 5M of being online

Click to expand... Yeah I went to that site, why do I need to buy a key?
I won't buy a key, stupid.

I'll revert back to windows 7 then.

When I still was on windows 7, about a year ago I added 4GB extra ram which is a total of 8GB now,
is that causing the problem?
