Using the Windows Task Manager

To determine the amount of RAM you'll regain by disabling unnecessary
system services, use the Windows Task Manager. Here's how: Before you
disable any system services, reboot your system and don't launch any
applications. If you have applications that automatically load when you
start Windows, hold down the [Shift] key to bypass the Startup folder.
Then, right click on the task bar and select Task Manager from the
shortcut menu. When you see the Windows Task Manager dialog box, select
the Performance tab. Now take note of the Available value in the
Physical Memory panel. After you disable those system services you deem
unnecessary, reboot your system in the same manner and compare the
Available value in the Physical Memory panel to the one that you noted
earlier.
