i wnt to known how to uninstall bluetooth driver from win7
You can uninstall the driver by going to start then right clicking on computer and go to Manage. The Computer Management MMC should display. From there on the left hand side go to System Tools then click on Device Manager. This is where you can manage all the drivers for your computer including Bluetooth drivers. Go to Bluetooth , right click and you can disable or uninstall the driver. If you uninstall the driver it will reinstall when you plug in a bluetooth dongle like previously stated.
