Windows 10: My windows suddenly doesn't activate

I've been using this laptop for 9months now with my windows 10 activated but all of a sudden the activate windows watermark appeared on my screen & when I checked further it showed : we can't activate windows on this device as we can't connect to your organization activation server . This is very annoying ,plz tell me how to fix it ASAP

Windows doesn`t start. Authomatic repair doesn`t work.

Thanks again!!

I`m sorry I had not noticed that the text on the picture was in spanish. It says that windows has replaced some damaged clusters in "name" file and "directory". Then, at the end "an unspecified error occurred (75736e6a726e6c2e 4f6)".

I`ll do it and I`ll be updating this thread when I have the report.

Activation of Windows 10 Pro doesn´t work

Hallo, i can´t activate my windows 10 Pro (free upgrade from windows 7);

Info: 0xC0EA000A

Manual activation doesn´t work either.

Important (i think): I had to re-install windows 10 (3 or even 4 times). because I had massive problems with "Start and Cortana Issues".

I hope, I don´t have to search the old product key.

PS. Yes, Windows 7 was genuine.
