After you uninstall a network adapter in the Device Manager on a Windows Vista-based computer, you receive the following message in the notification area at the far right of the taskbar:

Installing device driver software

Then, the network adapter is automatically reinstalled.

Note: When you uninstall a network adapter in the Device Manager on a Windows XP-based computer, the network adapter is reinstalled only when you right-click Network adapters and then click Scan for hardware changes.
