Windows 10: Reactivating Windows 10 Pro N after a hardware change. "We can’t reactivate Windows on this...

Recently changed my motherboard, CPU and RAM and reinstalled windows onto my ssd. After doing so I couldn't activate windows using the troubleshooter and selecting "I recently changed hardware on this device". I contacted support but they said I needed my window 7 license key which I do not have anymore. I triple checked before changing hardware to make sure my license was attached to my Microsoft account and it definitely was. How do I fix this?

Windows 10 reactivation on hardware changes

Hi Florea,

It is possible that Windows won't be able to identify your computer correctly that is why the operating system is not activated. To address your issue, we suggest that you follow the steps in this

Does Windows 7 require reactivation if...

He is using AMD already. He wants downgrading to AM3. Don't know why??

If you change HDD + RAM simultaneously, Windows 7 needs to be reactivated. Only HDD cloning shouldn't require reactivation. As you are changing mobo + HDD (prehaps RAM upgrade too), you will surely require reactivation. If you have genuine license, you should reinstall OS (you might use Windows Easy Transfer). If you don't want to reinstall, you need to uninstall HDD, interfaces/system devices, and numerous other drivers (USB, HID, Portable devices, etc.), else your OS will be unstable.
I will highly recommend to reinstall Windows 7 and enjoy your migration.

A simple trick might be like this to avoid reactivation:
1. Clone your HDD first and boot into Windows
2. Use it for at least one week
3. Replace mobo only without any other hardware change/upgrade and boot
4. Use it for at least one week
5. Do any other upgrade (RAM, Graphic card etc.)

Don't do two simultaneous downgrades/upgrades to avoid reactivation.
