Yep, changing hard drives should be no issue since both were upgraded, same as for the thread starter. I just learned here from a post that even changing a CPU and Motherboard along with a HDD on a PC upgraded to Windows 10 had no issues being activated, that i always wondered if possible being more major components.
I changed the drive and laptop booted fine. However i completely forgot when I upgraded Win 7 to windows 10 it was Windows 10 insider preview 10240 and later it was upgraded to Windows 10 when it came out. Windows 10 was upgraded to pro version instead of home. I kept it like that since. When SSD drive was inserted which Win 10 pro it showed Window 10 is not activated.
After reading many guides and forum on the net I was unable to downgrade to Win 10 pro to home.
I even changed product name and id using regedit and then ran media creation tool to install home version over pro for some reason that failed.
Finally decided to use Microsoft live chat, after explaining the issue, they suggested that they will install the correct version as a fresh install. I insisted keeping all files and programs etc. Microsoft ran some slmgr commands via cmd etc. They were about to install fresh copy but tried Windows 10 pro defualt key and it activated. Support guy was confused but happy that Win 10 pro was activated with reinstalling lol.
Somehow from insider preview i was upgraded to pro instead of home edition.
I still wanted to know the key of pro version and microsoft support guy came to this forum to download showkeyplus :) it shows the activated key.
I am glad its sorted but i am still confused that they used the standard key for pro, is that the key i need to use in the future to fresh install Windows 10 pro again?
