Windows 10: Windows 10 activation info?

I have an OEM desktop PC with an embedded Product key in the UEFI BIOS on the motherboard.
Until recently when clean installing using the Media Creation Tool I have never once seen the Activation screen appear that asks for a Product Key. I have tested this twice in the last few weeks though and both times I was presented with the Product Key Activation request screen. I just had to select I dont have a product key, then select Windows 10 Home as the OS to be installed and it was automatically activated during Windows Setup anyway. Its bugging me why this has suddenly started to happen. It has never happened before during many, many previous clean installations.
The Activation screen appears right at the beginning before you select Custom Install , delete partitions etc. Has anybody any idea why the embedded key seemingly isnt being read at this stage? Under normal circumstances, when it is read at this stage, is that when it immediately activates (If so, how?...does it connect to MS servers and activate?) or is the activation done later during Windows Setup ? The embedded key must be being read at some point because during Windows Setup the activation is being done automatically despite the fact that I havent entered a Product Key
How exactly does this activation process work on OEM PC's. I realise that I have a Digital Licence linked to my Microsoft Account but when clean installing with the Media Creation Tool it still must be reading the embedded key in the BIOS at some point..or am I misunderstanding how it works? Im hoping someone has some in depth knowledge of the procedure because Im baffled lol

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 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK

DOWNLOAD WINDOWS 10 NOW - Upgrade and ISO direct from microsoft

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?
