Removing a Steam account from my computer

[[skrrt] 1986 Toyota Corolla]

I am hopefully getting a new computer but my new steam account has no games so I'm going to use my old one.
However, I don't want to keep my old account on my new computer because the library becomes messed up. Is there a way to remove an account so next time I log in with the account I want removed after I have removed it it will say you seem to be logging in on a new computer please enter the code we sent to your email.

You can always refresh your Steam installation.
Close Steam, delete everything in the Steam folder except Steam.exe and SteamApps and doubleclick that Steam.exe.

I went to steam then to my config folder and deleted the previous users from "loginusers" and "config". These were both .vdf files.

Did this take a while?

My PC > Program Files (x86) > Steam > config > login users (open with notepad) > delete the paragraph with the account that you want to delete.
