Windows 10: Help my Windows 10 is gone

I bought a laptop it had windows 10 on it then I decided to test out the Enterprise Edition trial but I didn't write down the windows key code down so now I can't downgrade back to basic windows 10 & my trial version expires in 11 days, what I tried was factory resetting to my default windows keeping my data but it didn't put back the default windows 10 its still the Enterprise Edition...

So is that normal or do I have to do a full clean reinstall in order to revert back to Windows 10 basic, as its suppose to be hard baked into my Factory Reset on this laptop, why didn't it work, I don't or rather can't place a new windows 10 because it costs 100$ I already had it on my pc its part of the laptop & its model so how do I go about recovering my old windows 10 basic.

None of this was mentioned while upgrading I wish it would had stored my old windows 10 key code info for me, besides that the enterprise edition was misleading it was suppose to be a barebones OS with less cluster but it had the exact same stuff I was wanting off the pc to start with sadly I don't know what to do & don't feel like upgrading for a product that didn't meet my desires or paying for what a already had before hand.

I did back up my product key id but that's pretty much useless with the activation key lame.

Why did the startup window get cleared?

I didn't missed any step, the list was gone and gone , even after using lot of programs the programs were not listed in that list.

 

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
