Windows 10: Windows 10 activation key doesn't work after hardware change, troubleshooter doesn't fix it.

I followed all the steps after getting a hardware change changing motherboard etc. The message to activate windows popped up, I already have my Windows 10 license key and it says it's invalid. Running the troubleshooter doesn't work. I need help activating my legitimate copy of Windows without me having to buy another product key.I have Windows 10 Pro.This is the error I get: 0xc004c060

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.

I ran SeaTools. These are the results:




Does it mean my HDD is useless?

Thanks for your answer, ken!

I deleted all my data. I had have it backed up.

I did a clean installation using the windows media creation tool (usb option).

No, I didn`t. I thought a clean installation would solve the problem.

After posting my previous message, I did it.





After chkdsk, I close cmd and tried to boot and the laptop just turned it off. This morning I`ve restarted it and automatically windows did a repair. Windows has booted and it seems that the repair tool has removed chrome and acrobat pdf reader (the only two programs I had installed after reinstalling windows).

Now Windows is installing updates and restarting my lapop, I`m kind of frightened. I don`t want it to happen again. Anyhow, I want to know what has brought the issue

I`ve been looking for information about the error code at the end of the picture and I didn`t get anywhere.

 

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.
