6. TASKLIST and TASKKILL: Taming Resource-Hogging Processes

One common reason for a slow computer is resource-hogging processes running in the background. The “TASKLIST” command shows you a list of running operations, and “TASKKILL” lets you remove those you don’t need. This helps free up system resources and can lead to a significant speed boost. Just open Command Prompt on your slowed-down computer and type “tasklist” to see a list of processes. Identify the culprits and use “taskkill” to stop them.

7. MSCONFIG: Streamlining Startup Programs

When your computer starts up, it loads various programs in the background, which can slow it down. The “MSCONFIG” command lets you manage these startup programs.

Internet connectivity issues and slow browsing can sometimes be attributed to outdated DNS cache. The “IPCONFIG /FLUSHDNS” command is your remedy.
