I wonder if you just revealed you have no backup and restore plan.
PCs have never proved reliable to go without. To "transfer" them is also not a good idea. We never "move" or "transfer" files. It's best to copy them so if something goes wrong we can try again.
That all said, a memory stick is a pretty basic tool to do this.
How hard is it to transfer files such as pictures, from a Windows 7 laptop to a Windows 10 laptop ?
