A roaming profile keeps your personalized settings on a network server. These settings are copied to each computer as you log into the network. When you browse the Internet with Internet Explorer, all the files on each Web page are copied to the Temporary Internet Files folder on your computer. When you are set to use a roaming profile, these files become part of the information copied to your home directory (which stores your personalized information). When you log in to the network from a different computer, these temporary files are copied to the local computer. Each time you browse new Web pages, the number of files increases. Having more temporary files can increase the time it takes to log in to each local computer.

Configure Internet Explorer to keep temporary Internet files on your local computer using a .reg files.
