Have I Done Everything?

Having bought a new computer, I want to remove everything I need and want off my old machine. I have copied, and temporarily transferred to an external hard drive, everything in the following:

• Documents
• Firefox Bookmarks
• Music
• Pictures
• Videos

There are three user accounts on the PC and I’ve done this for all three. Any software I have and want to keep, e.g. Belarc Advisor, Malwarebytes, etc. I can download onto my new machine.

I can’t think of anything else. Is there anything you think I’ve missed and should have checked/looked for?

Thanks in advance.
