Easiest way to transfer files to new drive

[IdentityZER0]

Hello everyone, I recently bought a PC from my friend and I put my GTX 970 and my hard drive into it. My hard drive is a TOSHIBA 5400rpm 1 TB drive (I have about 750GB used so I'd have to clear some space) and his is a western digital 650 GB 10000rpm. I want to delete everything off his hard drive other than windows and put my files onto it. What's the easiest way to do this? When I am on my hard drive I get the "Activate Windows" watermark in the corner because my Windows is linked to the registers of my old computer. Any help is appreciated.

Thanks

You mostly can't do that.

1. You can do all the Uninstall you want, but there will be lingering bits of 'him' in that Windows install
2. Your specific applications would need to be reinstalled. You can't just 'move them'
3. Finally, for any used PC, you really, really need to do a full wipe and reinstall of the OS. For your protection as well as his.
Wipe it completely and reinstall.

And taking your current install on the 1TB, with 750GB used, reducing it down to 600GB or so, and then cloning it on to that 6050GB drive will result in exactly what you see now with "Activate Windows".

If I still have his windows key when I go to the activate page on my hard drive could I put in the code or would that mess things up as its like two different Windows 10's?

Yes, if you have that license key, it will probably work.
