If I upgrade from Win7 to Win10, can I transfer that key to Win7 at a later or is it locked into Windows 10 forever?
Background (Optional read): Outlook was crashing constantly the other day, ended up system restoring, fixed outlook but the PC is performing painfully slow now. I could upgrade it to Windows 10 (if it works it is software problem), or transfer the image to a new laptop (if it works it is a hardware problem). I'd like to know the answer to the question in case the PC is still slow after the 7->10 upgrade and I need to image the computer to the laptop.
Any answers or suggestions are much appreciated!
