I recently picked a 250gb m.2 vnand drive for my OS, i am going to install windows 10 on it but what would be the best way of removing windows 10 from my current 1tb hdd so i am still able to use the programs/games saved on that drive? Also i bought this ssd brand new from bestbuy, and when installing it i found it already had windows 10 installed and some random kids games/files and even resume with address and all? is this normal lol??
