Dell OptiPlex GX260 User Guide - Page 208

DVD software shuts down and requires a restart when the user comes back. Computers with low memory configurations can experience problems. The computer uses memory to keep the first user's programs running in the background while the second user is logged on. On computers with limited memory, this can cause the entire computer to run slowly. Fast User Switching is off by default on computers with less than 128 megabytes (MB) of random-access memory (RAM). Fast User Switching is unavailable if the computer has Windows XP Professional installed and is a member of a computer domain.
