Windows 10: Window 10 activation and lincese with non valid or pirate OS

Hi, I'm not an expert in softwares and I'm so confused right now.



I got my laptop fixed 6 months ago and had to install a new OS
so the repair store got me windows 10 ("windows 10 Enterprise"). When I required a product key, they said it already is installed(?) embedded(?) within the system so they don't know the key and I wouldn't need it in the future.


but today I got a system alert that says the license is about to expire and I need activation.

So I went back to the store, and they activated it but I found a text file on desktop named "R@1n"
And i couldn't understand what this file says exactly but I'm now suspicious that they got some random pirate product key to activated it.


I really don't understand how this could all happen.

I had no problems until now, so does that mean I have been using this OS without activating it for the past 6 months?
Also, if they installed a valid, proper license, why would the system tell me it's about to expire?

And what is this R@1n?


If someone could kindly explain it to me I would very much appreciate it.

:)

 

Downgrading from a pirated Windows OS

You've already mangled your existing operating system by upgrading to a pirated version of Windows 10. Use your Windows 8.1 disk to do a new installation of your original Windows 8.1 operating system. If you have saved the product key from your original Windows 8.1 operating system, then use that product key again to install Windows 8.1.

You can downgrade from Windows 10 to Windows 8, by following the instructions in the answers to this question: How can I downgrade from Windows 10 to Windows 8?. Why not downgrade the pirated Windows 10 to Windows 8 instead and then change the product key and upgrade legally back to Windows 10? There are two reasons for not doing it this way:

1. Your new Windows 10 can inherit problems from the pirated version of Windows 10.
   
2. It's a two-step process to install Windows 8.1 and upgrade to Windows 10 instead of a four-step cumulative history: Windows 8.1 -> pirated Windows 10 -> downgrade pirated Windows 10 to Windows 8.1 -> upgrade to Windows 10. Even though the two-step method doesn't save any time, it still eliminates two unnecessary steps.

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?
