Ultimate Windows Tweaker is a freeware utility for tweaking and optimizing Windows Vista, 32-bit & 64-bit specifically.
This small (235KB), program has a clean, easy to understand interface that gives you access to over 150 system settings, some of which are hidden, and others that are just hard to find. The interface is organized for easy navigation, and it is complete with detailed descriptions for easy reference.
The major benefit in using this type of tweaking application is the ease with which you can make changes to your system, without the drudgery of having to go through menu after menu, or manually editing the Registry to get the results you want.
However, as with any application that makes changes to your system, use caution and be sure to have a verified backup. Fortunately, Ultimate Windows Tweaker allows you to create a system-restore point before you make any changes.

This is a very difficult question to answer given the lack of info on the
specifics of your machine, system configuration, installed software, etc.
Checkout “Slow Computer? – 6 Free Solutions” on my site, that should answer
some of your questions.
