Hello, my hard drive was just recently corrupted and completely broke. I had to install a new one and lost all of my data on my old drive. After booting up Windows 10 on the new drive, I find that I need the product key to fully activate my copy of Windows. Unfortunately, I misplaced the key and do not know where it is. I already bought the retail USB license of Windows 10 a while back and used the key to activate it on my old drive, so shouldn't there be a way to sync my windows account to my new drive and fully activate my OS? Without activating Windows I cannot do any customization and there are many minor annoyances, any help would be much appreciated, thanks.
