How to View L2 Cache Memory on Windows XP OS

1. Click the 'Start' menu button in the lower left-hand corner of the Windows XP screen.
2. Select 'Run' from the pop-up menu.
3. Type 'Regedit' in the Run dialog box (without quotation marks). Click 'OK' to launch the built-in Windows registry editing software.
4. Open the Memory Management registry folder in the Regedit screen by clicking the 'HKEY_LOCAL_MACHINE' folder, then opening 'SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\.' This folder lists all memory usage in the Windows XP operating system.
5. Review the 'SecondLevelDataCache' pop-up window to view the size of the L2 cache memory in Windows XP. Type a new value for the cache to adjust the size of the CPU L2 cache memory. This number should be adjusted in decimal format. Close the window to exit the registry edit software.
