So I recently switched my laptop's HDD to a SSD and used my old windows 8 install CD that I had already used on my desktop and surprisingly enough it actually activated perfectly. I deduced that since my desktop had been unpdated to Windows 10 the Windows 8 key wasn't bound to it anymore. from this one install CD I have now two fully fonctional Win10 rigs with two different product keys. theorically this could be done infinitely as long as win10 is a free upgrade from win8. I'd like to know if this is a bug on my side or is it possible for everyone? does it also work on win7? Thank y'all in advance -koolkimoov

The CD lacks the necessary key. If the Windows version you have matches the one already installed, the UEFI on the laptop would have triggered activation automatically. EdIt: It seems you likely used the previous DVD and didn't input the product key from your desktop.

Certainly, during the setup I used the key that came with the DVD. I assumed it would complete the installation before realizing Windows wasn't actually activated... but that didn't occur.

It has been emphasized repeatedly: avoid entering a Windows 10 product key unless you truly possess a valid 10 key, not an 8. Microsoft apparently chose to include Windows 8 keys within the 10 product configuration, yet restrict access from their servers.

You got it wrong, I activated Win8 using the product key and then upgraded with the "get Windows 10" app.

You installed Windows 8 from disk on machine #1, then upgraded to Windows 10. On machine #2, you installed Windows 8 from the same disk and activated it successfully before upgrading to Windows 10. You now have two Windows 10 activation keys. This suggests your Windows 8 key might still be stored in the system databases during the upgrade process. If you upgraded machine #1 directly to Windows 8.1 for free before moving to Windows 10, and machine #2 was upgraded straight from Windows 8.0 to Windows 10, it’s possible the keys were retained.
