How to active my Windows 10 pro 64bit from old motherboard.?

Hi Roomies,

I have been trying the last 2 days to get the internet working on my new used motherboard and because I wanted to have it done asap. I took it back to the shop that did the work and they couldn't fix the problem, so they installed a cleaned version of win 10 pro, problem solved.

The only version that I have with probably the digital license is on my usb stick that I burned back in May. So please let me know how can I do it best.

Thank you.

A new motherboard is a dramatic change, you could try this:
If you made a significant hardware change to your device (such as replacing the motherboard), Windows 10 might no longer be activated and you might see the activation error codes 0x803f7001 or 0xC004C008. If you're running Windows 10, version 1607 or later, and added your Microsoft account and linked it to the digital license on your device, you can use the Activation troubleshooter to reactivate Windows. For more info, see https://support.microsoft.com/en-us/help/20527

If your Original Hardware Manufacturer (OEM) changed the motherboard for you, your PC should reactivate automatically or you should be provided with a replacement product key. If you see the Activation error “Unable to reach Windows activation servers” then follow the steps in this additional help article. https://support.microsoft.com/en-us/help/4023300

@Bastet,

Thank you for a quick response. I was able to consolidate all my MS accounts and log in and still got activation error codes 0x803f7001.

My orginal license Win 8 Pro I bought direct by MS and I still have the code keys if that helps in getting back my Digital license back. Please let me know which other steps I can take without doing again a clean install but this time with my MS usb stick.

Thanks

You could try this:
To use your Windows 7, Windows 8, or Windows 8.1 product key to activate Windows 10:
Select the Start button, then select Settings --> Update & security --> Activation.
Select Change product key, and then enter the 25-character product key.

@Bastet, Great it worked!! my Win 10 Pro 64bit is activated!!
