Windows 10: Unable to reactivate windows after upgrades.

Hello. I have upgraded my motherboard and CPU but my windows 10 got deactivated. And when trying to reactivate my windows using the "I recently changed my hardware on this device button" in the troubleshooter it displays a message saying "Unable to activate windows". Does anyone know how to fix this? I have included an image of the message that gets displayed below.

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.

Then why does it say fs/ft i7-920 in his tag and he wants to downgrade to am3 system? to go from a am2/2+ to am3 isn't a downgrade last time I checked

 

Unable to reactivate windows

Hello, I have upgraded my PC (I changed the motherboard, CPU, RAM, SSD) and when I try to log in to activate windows it says that it is unable to reactivate windows on my device. I am unable to afford a new windows key, is there anyway I can just
reactivate the windows my computer had previously?
