If you want to manually flush your DNS cache on Windows 10, you can use Command Prompt or Windows PowerShell. Some commands must be “Run as administrator”

With either Command Prompt or Windows PowerShell opened, type ipconfig /flushdns, and hit Enter.

If the DNS cache was flushed, you should see the “Successfully flushed the DNS Resolver Cache” message. You can now close the window.
