Below are recommendations users can follow to help speed up a computer and make it run faster or determine why a computer is running slow. It should be noted that this page only covers an overall slow computer and not a computer that starts slow or has a slow Internet connection. To diagnose those issues, visit the following pages:
If your computer has not been rebooted recently, make sure to reboot it before following any of the steps below. Rebooting the computer can fix many problems and is an easy first step.
One of the most common reasons for a slow computer is programs running in the background. Remove or disable any TSRs and startup programs that automatically start each time the computer boots.
To see what programs are running in the background and how much memory and CPU they are using, open Task Manager. If you are running Windows 7 or higher, run Resmon to get a better understanding of how your computer resources are used.
If you have an antivirus scanner on the computer, a spyware protection program, or another security utility, make sure it’s not scanning your computer in the background. If a scan is in progress, it decreases the overall performance of your computer. If this is the case, allow the scan to complete, and the computer’s performance should improve.
Delete temp files
As a computer runs programs, temporary files are stored on the hard drive. Deleting these temp files helps improve computer performance.
First, we suggest using the Windows Disk Cleanup utility to delete temporary files and other files no longer needed on the computer.
Unfortunately, Disk Cleanup may not delete every file in the temp directory. Therefore, we also suggest deleting temporary files manually.
- Open the Start menu or press the Windows key, then type %temp% in the Search field.
In Windows XP and prior, click the Run option in the Start menu and enter %temp% in the Run field.
- Press Enter and a Temp folder should open.
- You can delete all files found in this folder and, if any files are in use and cannot be deleted, they can be skipped.
Free hard drive space
Verify that there is at least 200-500MB of free hard drive space. This available space allows the computer to have room for the swap file to increase in size and gives room for temporary files.
