What should i uninstall to get my computer faster also what should i change on my computer to play games?

Just take out what programs you don't use preferably everything HP& power2go (usbflash software) the rest depends on you and your usage. You can end your processes too through task manager but you will need to stop them from startup as well. In windows 7 type msconfig in your search bar at the bottom- after clicking start. Check off the running programs you don't want to "startup" at startup, mostly just check off what you see that isn't important. If you're unsure what something is GOOGLE it! =D
