When multiple users share computers, privacy becomes an issue because you don’t want the next person who sits at the computer to know what you were doing. You can make Windows secure and ensure your privacy in a network environment by opening the local security policy on your PC. In Windows Server 2003:

1. Open the Start menu, select Control Panel, and double-click AdministrativeTools.
2. Double-click the Local Security Policy applet.
3. Expand Local Policies in the left panel and select Security Options.
4. Scroll to the bottom of the list and double-click the option to Shutdown: Clear Virtual Memory Pagefile.
5. Select the Enabled radio button and click OK.
