 Step 4 – Use Only One Antivirus Program
 Step 5 - Fix Windows System Files

Step 1 - Uninstall Unnecessary Programs

Nearly every new computer comes with pre-installed software. Most of the pre-installed software is useless and will overuse system resources. Look through the programs and uninstall the ones you don't need. Also, if you installed software that you no longer use, uninstall it. How do I uninstall programs?

Common pre-installed software include antivirus trial software, search engine toolbars, games, and music services.

Step 2 - Remove Temporary Files

In order to speed up web browsing, web browsers store visited web pages on the computer’s hard disk. These web pages are stored in the temporary Internet files (cache) folder. When this folder fills up with too much data, the computer's performance can suffer. Additionally, Windows and many programs create temporary files when they run.

Step 3 - Scan for and Remove Malware

Malware is the general term for viruses, trojans, spyware, rootkits, and any other malicious software. If you think your computer might be infected with malware, follow the steps in this malware removal guide.

Step 4 – Use Only One Antivirus Program

Make sure that you are not using more than one antivirus program on each computer. Running two or more antivirus programs is likely to cause a conflict, which could result in crashes, error messages, or slow computer performance. Also, make sure that you are using reputable antivirus software: Best Free Security Software for Windows

Step 5 - Fix Windows System Files

Windows system files can become corrupted due to various reasons. Fortunately, Windows has a useful tool called System File Checker (SFC) that scans for missing or corrupted system files and repairs them.

To use System File Checker, press the Windows logo key and the R key together. Then type sfc /scannow in the box and click OK
 + R

Note: There's a space between sfc and /scannow. Once the scan is complete, restart the computer. 


If the computer is still running slow after following all of the above steps, you may want to consider buying a new one. If you like this guide, please share it or leave a comment.
