Many Dell Laptops start to lag on performance after enough usage is put on the laptop. There are several ways to tweak the performance of a Dell laptop directly within Windows. This is a very simple method of making a Dell Laptop run faster in that no downloads are required and no additional software needs to be installed.
Clean Up Windows
Start by doing a system cleanup. Navigate to Start - All Programs - Accessories - System Tools - Disk Cleanup to access disk cleanup. Disk cleanup gives a list of many different types of files that can be safely removed from a computer. Be sure to read the description next to each file type before deleting. You may want to keep some files.
Use the built in Windows defragmenting utility to defrag the Dell laptop's hard drive. This moves many of the hard drive's files and data to different locations, while also grouping similar items together so that Windows can conserve hard drive space. Navigate to Start - All Programs - Accessories - System Tools - Disk Defragmenter to use the defragmenter utility. Choose to analyze the disk first before defragmenting. This will give a rough estimate of how files can be relocated on the hard drive.
Tweak Always Run Startup Programs
Access the System Configuration options panel from the Run menu. Use the Start menu to get to the Run menu by either typing "run" into the search bar or navigating Start - All Programs - Accessories - Run. Type the text "msconfig" into the run menu. Choose to use a selective startup by selecting it from the general tab. Use the startup tab to toggle off unneeded startup programs. Restart the computer to enable changes.
Uninstall Applications That Are Not Being Used
Navigate to the "Programs and Features" panel by selecting it from the Control Panel. Select any currently installed programs that are not being used, and click the uninstall button to remove the program from the Dell laptop.
Adjust Default Windows Performance Options
Make adjustments automatically using the Performance Options panel. To access it, right click the "My Computer" icon on the desktop and select "Properties." If there is no "My Computer" icon on the desktop, navigate to the "Computer listing" in the Start menu. Right click it and select "Properties." Navigate to the "Performance Information and Tools Pane" by selecting "Performance Information and Tools" from the left-hand sidebar. Use the "Adjust Visual Effects" option. Uncheck some menu items from the visual effects box or select "Adjust For Best Performance."
