Windows 10: Activating a Windows OS copy without Product key.

I recently did some upgrade to my laptop and added a SSD as primary drive and the previous HDD drive containing the activated windows OS was formatted. Is it possible for me to somehow recover the previous OS or if i can activate the new windows OS copy without product key ? As i don't know the product key of the genuine windows OS copy i had

:)

 

lost windows activation key, need new free os thats just as easy as windows

I confirmed this, although it listed a different product key than the one given for my copy of XP. 0.o

 

Windows 7 not genuine problem

It seems like that's an OEM windows copy, it will do that the every time you reinstall the OS. If you have the key, next time you see the "not genuine windows copy" click it and choose to activate by phone, everything else is pretty straight forward as it explains step-by-step. If it doesn't work, then its highly likely that you got a Pirate copy.

 

Windows 10 product key error

Hi Piyush,

Thank you for posting your reply.

I suggest you to activate the copy of Windows via phone by following the steps below:

• Press “Windows key + R” and type “slui 4” and press Enter.
• Select your Region/Country.
• Select the Phone Activation option, and hold on for a real person.

Hope the information is helpful.

Regards
