So on my previous laptop I had a window 10 home which i bought through store (digital license). Now I bought a custom desktop and won't be using the laptop anymore.Then I install windows 10 home on the new desktop. The window 10 home wasn't activated but I upgraded it to window 10 pro. Now even though i already sign in and troubleshoot, my window 10 pro won't activated. Based on my research , it seems that window 10 home should be activated initially , and then can be upgrade to pro which I didn't do.
How can I solve this problem? T_T
