About Storing User's Profile
In Windows domain, a user's profile is stored on the local computer.
When a local user logs on to that computer, that user's profile on the local computer is uploaded into the user profile in that computer's registry. When a user logs out, that user's profile stored on the local file system is updated, ensuring that the Windows Domain user or the Windows Local user always has the most recent user profile version.
