How to delete old DNS records on you Windows computer?

More than ones my PC was showing me an old website after changing the DNS records successfully. My Mac computer was already showing the new website, and if I looked up the DNS records on a web service like: intodns I could see that the DNS records were configured correctly.

If you ever run into this problem just reset the DNS table on your Windows computer. And that's how it's done:

Click on the Windows START button / open the system console (CMD) / and make the following entry:
ipconfig /flushdns

Done. Now your Windows computer will also show you the new website!
