If a company disabled an ex-employee's access by revoking his user id. Does that mean nobody can access his windows profile?

i.e cannot logon his computer to access his files? If a user id is revoked, can a manager still get the user id and password, log on to ex employee's computer?

If they have physical access to the computer, it's safe to assume if they wanted in, they have access.

Anyone with Admin privileges can access their profile and files.
