Optimize for Speed
One major cause of system slowdowns is a bloated Registry filled with out-of-date or bad entries. Your Registry gets junked up in many ways, notably when you uninstall a program that is ill-behaved and leaves traces of itself behind. As a result, one of the best ways to improve PC speed is to use a Registry cleaner or fixer. Plenty of for-pay fixers exist, but if you want just the basics, Eusing Free Registry Cleaner is a good bet. It scans your Registry for problems, reports on what it finds, and then fixes the problems you tell it to address. You can also restore your original Registry settings if the new ones cause problems themselves.

Cleaning your Registry with a tool such as Eusing Free Registry Cleaner (see above) will go a long way toward improving PC speed--but it won't go all the way. Even after you scrub the Registry, it may still suffer from bloat, because over time the Registry becomes defragmented, particularly when you add and remove entries. The free, simple Auslogics Registry Defrag utility defragments the Registry and gains you a bit of hard-disk space. More important, though, is that it speeds up your computer's access to the Registry by compacting it--and that means a faster PC. The program is free, it's simple to use, and it revs up your PC...what else could you ask for?
