I have had XP installed on my machine for 5 years. In the past 6 months I have started doing regular registry cleans. I have uninstalled my old software. What I want to know is why microsoft word opened in one second 5 years ago but takes 10+ now. I am upgrading the RAM but that does not fix the problem it just gives it more space to hide. Please tell me what programs I should use to make the thing run faster or should i just re install xp?
