Will HP Library and Tape Tools increase my notebook performance?

Hello, I am trying to find a way to improve the performance of my notebook. I have an HP Core 2Duo T5670, 1,8 GHz, 2GB RAM. I used to have win xp,but now I have upgraded to win 7 and it works better. Searching the internet, I found a diagnostic tool, HP library and tape tools, and I want to know if it is good for my notebook. Thank you.
