Im just going to write my questions in a list. Thank you in advance for anyone who took the time to help.

If I drag and drop the C drive from one computer to the other, or to a flash drive, will that be it? What other sections of the computer would need to go with it (im wondering about the My Documents folder as well)?

If I drag and drop the C drive, that drags a lot of Windows 10 programs to a Windows 11 computer. Will that cause issues?

Are there any precautions or anything Im missing? Thank you.
