Windows 10: Windows reactivated after deactivation

So I installed windows 10 pro and was interested in seeing how it look activated so when one one person posted a key on facebook (Multi licence I guess) so I tried it and windows activated then after few hours I removed the key using a command I found online and it went back to showing the floating watermark which was annoying and I clearly remember how it annoyed me while reading news notification after the deactivation event for some good time but it suddenly hit me now, the the floating watermark is gone, not just today, I feel it has been like this for some time but I totally did not notice, I checked windows activation page and it is indeed activated and I 100% sure I never used the key again and no to do this beside me, any idea what happened?

Windows 10 reactivation after deactivation

hi

I accidently deactivate my Windows 10 on my laptop . How can I reactivate it ? Windows 10 ist upgraded form windows 8.1 and I don't have de product key or ID.

 

windows 10 deactivated how to reactivate

My grandson somehow deactivated windows 10. I have a refurbished Dell that came with windows 7. I had updated to windows 10 when it came out. I have a product code for windows 7. what option do I use to reactivate windows?

 

Want to replace my Windows 7

Hi All,

I suspect that my Windows 7 installed on my PC may not be genuine - I have taken steps to purchase a genuine version on Windows 7, and need some help to "convert" over.

I guess I need to somehow deactivate the current version of 7, and then reactivate with my genuine key. Does that sound correct, or is a different approach required? If so, can anyone offer me the best advice to do this?

Thanks.
