Hi Experts

Could you point how could I reuse a Windows10 official license I had after had to change the original HD?

Last month in a hurry I had to change the original HD that came on my laptop to an SSD HD due to performance issues.

How could I reuse its license since the Windows claim to "Reactivation" - how could I obtain the official license from the previous HD?

Thanks in advance

If you have the key and is original then Ms will reissue your license....

As it is try to Reactivate ... if it fails give them a call.

Is this version is OEM license? 

Have you tried installing windows with the recovery image?

What brand is your Notebook? visit their site and download the recovery image and install it using that.

Hello There

Changing the HDD isn't usually a problem if you know the license key or have a Microsoft account linked to the license.

If you don't, call Microsoft support what to do next.

Thank you for the replies!

I'm still reading it...

Just to clear: when I bought this laptop the official Windows10 came with a kind of firmware license, I guess....

I don't know how to obtain it to apply on the SDD I had to install, after... considering that it really makes sense.

Just follow MASQ's solution....

What you might be thinking of is a licence code embedded in the laptop's hardware?
See my Windows 8 article on this which applies equally to Windows 10
The key isn't stored on the drive so swapping the drive over won't mean you need to replace it.

I'm following your instructions and actualizing Windows.

So, if correctly undesrstood your article the ID's would be get directly from BIOS (since this is an official Microsoft  laptop provider) and after that will be actualized, isn't it?

Activate Windows

Access settings to activate Windows.

Would be corrected?

If it was provided with an operating system by the manufacturer (OEM) and was running an activated version of Windows 10 prior to changing the drive, yes.

Returning back after complete actualization, following your sugestions..

It looks OK!!!
