Nothing has changed in my PC but shes running a little sluggish and i do wish to toss in another SSD for more storage. Just wondering can i reformat my current SSD and use the same copy of windows 10 that i got when i built the PC? along with the key of course. (no its not an OEM key its a retail key paid the full 150 canadian at the time -.-).Just curious if i will come into issues trying to feed it the same key i used when i built the computer a year or so ago? I mean it shouldnt as all im putting in is a new SSD to go with the old one right?
