Although you can upgrade hardware on your Dell laptop to make run faster, a little tweaking of the operating system can accomplish the same thing. Any active program or feature takes up resources that degrades system performance. Disabling software, such as startup programs, display components and even viruses, frees up the resources required for such processes. This reduces the resource requirements for your system, which is effectively the same thing as adding more resources. To put it in perspective: You could earn $100, or you can save $100, but either way, you have $100.
Install and run a fully updated anti-software program, such as Avast!, AVG or Avira. Although adding software is contrary to the idea of reducing system requirements, this is necessary to eliminate memory-hungry viruses, which should never be allowed to persist. If you don't want to run the anti-virus all the time, you can always configure it not to run at startup.
Disable startup programs. Click the "Start" button, type "msconfig", and press "Enter." Uncheck any non-essential processes from the Startup tab, and press "OK." This prevents them from running at Windows startup. Office utilities, updaters, graphics programs and similar processes do not need to run at startup. However, you probably want to keep anti-virus and firewall programs running to keep your system protected.
Disable unnecessary Windows graphics. Click the "Start" button, type "appearance" and click "Adjust the appearance and performance of Windows." Click "Adjust for best performance" and click "OK." Although many pretty effects will be disabled, this can make your Dell laptop significantly faster.
