Windows 11
So, I have a Win 10 OEM install disk and I used that activation number to activate my current Win 11 install. I want to install Win 11 onto another disk (an SSD). Can I use the same code to do that? And how many times can I use that code to install Windows?

BTW, my next install will probably be my next "permanent" install.

I believe that as long as it's the same motherboard, you can install Win 11 as often as you want.

And here's ten points for filling out your computer specs.

Yeah, you can do that, assuming you're only activating one copy of Win 11.

Actually if the only thing you are changing is the disk then you don't need a key at all.

When you first activated Windows on this PC a digital licence for Windows 10/11 was stored on the Microsoft activation servers and linked to the unique hardware ID of this PC. The disk is not part of that hardware ID (the motherboard is). Windows 10 and Windows 11 Digital Licencing explained

You can change the disk and clean install Windows. When asked for a key click on 'I don't have one'. Windows will be installed with the generic key, which will activate from the existing digital licence as soon as it can contact the activation servers.

    fully 'Windows 11 ready' laptop. Windows 10 C: partition migrated from my old unsupported 'main machine' then upgraded to 11. A test migration ran Insider builds for 2 months. When 11 was released on 5th October 2021 it was re-imaged back to 10 and was offered the upgrade in Windows Update on 20th October. Windows Update offered the 22H2 Feature Update on 20th September 2022. It got the 23H2 Feature Update on 4th November 2023 through Windows Update, 24H2 on 3rd October 2024 through Windows Update by setting the Target Release Version for 24H2, and 25H2 on 30th September 2025 through Windows Update by setting the Target Release Version for 25H2.

    UPDATE - 11 April 2026: due to mechanical deterioration this PC has been retired from active duty. The OS with all software and files has been migrated to my System Seven in 'Other systems' to carry on as my general purpose 'main machine'.
