Welcome to DNS Flush Tool, a small Windows utility designed for anyone—no coding or technical skills needed. If your internet is slow, websites won’t load, or you see “DNS error” messages, this tool can help you reset your computer’s DNS cache and get you back online.
Flushing your DNS cache clears outdated or corrupt address records that your computer stores. With DNS Flush Tool, you don’t need to open Command Prompt or remember any commands. Just download, run, and follow the guide.

Follow the wizard – The setup process will guide you through a few screens. Accept the default options and click Install.
Launch the tool – Once installed, find “DNS Flush Tool” in your Start Menu or desktop shortcut. Open it.
