Hamachi puts its virtual network adapter at the bottom priority in Windows. This is done to ensure there are no conflicts when Hamachi runs on an Active Directory Domain Controller or DNS server.

1. Go to the Advanced Settings of your computer:
   1. On Windows XP, go to Control Panel > Network Connections > Advanced > Advanced Settings
   2. On Windows 7 and 8, go to Start, type ncpa.cpl in the search field, and press Enter. Then press Alt to show the menu bar, and click Advanced > Advanced Settings.
2. Use the Up/Down buttons to reorder the network adapters to your preference.

   Result: Hamachi will perform best at the top, but the difference is very minor in all but very intense usage, and may cause compatibility issues with other Network-centric tasks.
