Flushing the DNS cache on Windows 10 is a simple process that can often solve internet connection issues and improve browsing speeds. By following a few easy steps, you can clear outdated or corrupt DNS entries from your computer, ensuring it has the most up-to-date information for resolving domain names. Let’s dive into how to do it.
How to Flush DNS Cache Windows 10
When you flush the DNS cache on your Windows 10 PC, you’re essentially clearing out the stored information that your computer uses to quickly resolve IP addresses associated with domain names. This can help fix connectivity issues and ensure your browser is accessing the correct websites.
Step 1: Open Command Prompt
First, you need to open the Command Prompt with administrative privileges.
Press the Windows key, type "cmd," and when the Command Prompt appears in the search results, right-click it and select "Run as administrator."
Having the Command Prompt open with admin rights is crucial because flushing the DNS cache requires elevated permissions on your system.
Step 2: Execute the Flush Command
Once the Command Prompt window is open, type the command ipconfig /flushdns and press Enter.
This command instructs Windows to clear the DNS resolver cache.
Step 3: Confirm the Action
After executing the command, you should see a message that says, "Successfully flushed the DNS Resolver Cache."
This confirmation message indicates that the DNS cache has been cleared successfully.
After completing these steps, your computer will clear the stored DNS data and will start fresh, pulling updated DNS information as needed.
