Windows 10: Windows reactivation after resetting computer

Recently I had an issue where a Windows update downloaded wrong and my keyboard and mouse stopped working when Windows actually started.
That's not my current issue, I have resolved that, I only mention it to explain why I had to do a reset.

anyways


My current problem is after resetting windows via the advance startup mode Windows now wants me to activate it again. I originally downloaded windows 10 in 2016 via a USB that I got from a store, but have since thrown away the packaging, but kept the USB. To activate Windows, I seem to need my product key, which I don't have a physical copy of anymore.

what should I do about this?

Windows reactivation after computer change

Hi all!
I searched trough existing threads for help but without success, so I'm opening new one.

I have a Win 10 digital license that I picked up a few years ago when MS gave a free upgrade from 7 to 10.
This license is properly linked to my Microsoft account on my old PC.

Now, I bought a new computer, so I was thinking of reactivating windows on a new machine, but it turns out it's not as simple as the instructions says:
https://support.microsoft.com/en-ph/...ardware-change

I signed in on new PC with my active account but when I try to activate windows on new machine trough Troubleshoot it is not displaying new PC in the list of computers associated with the MS account.

Does anyone know if Win 10 can be reactivated after a computer change?

According to Microsoft I need to buy new licence, but also I found info that it can be activated but you need to add a new account (option that I don't have since I'm already signed in)..

Any help is highly appreciated.

 

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.
