All I know is what works for me. Here are some simple ways you can speed up your computer. 1. If you use an OEM machine, uninstall the massive worthless bloatware they have a tendency of installing. 2. Install all important Windows updates. 3. Defrag your PC at shutdown. If you dont know how to do this, it's a google search away. 4. Disable services you dont use at all or ones that dont do anything, such as the defragment services. If you dont use wireless disable the wireless service. Just dont disable anything until you know what it does. The services applet can be found holding the windows key and hit "R" and typing in "services.msc" double click them and if you feel safe disable one click the drop down box and select "disable" 5. using the run menu open up msconfig. In start up, check off boxes of things you dont want starting up. 5. Dont use Internet Explorer since it's poorly programmed and runs very slow no matter what you do. I suggest Firefox, it's a much faster browser and more secure. 6. Make sure you have more than enough memory for your Windows OS. Windows 7 needs atleast 1 GB, Windows XP needs atleast 512 mb. Windows vista atleast 2gb and upwords. Not sure if this helps anyone. Though I know it helps me.
