You will need a file unzip program like WinZip to extract the 2.36 MB zip file. Close all programs before executing the setup.exe program. When setup is complete, click on the Finish button to reboot your computer. Like most high quality software, Sandra comes with an uninstall utility. Sandra also comes with a browser based FAQ file and a browser based help file, but the help file is Web based.

Sandra's Performance Tune Up Wizard advises you about what hardware upgrades would be best for your system. However, you don't have to run Performance Tune up Wizard because each module also provides you with performance tips. For  example, the multimedia benchmarking module warned me that my on-board video's use of shared memory greatly reduces performance and that I should use a video card.

It's fun to open the various modules and probe your computer system. I found the most interesting module to be "Processes Information". You can start any program and find out how much memory it uses and what DLL's it uses. Sandra System analyzer, diagnostic and benchmarking modules are one tool every PC technician should definitely have in their toolkit.
