DTS supported natively by Windows 8/8.1 and it should work on windows 10 too just DDL require to unlock your driver .

 

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.
