USB ports are becoming serious headaches to System Admins and ordinary PC owners. With USB ports open a system becomes vulnerable to outside virus/worm/trojan threats and corporate/personal data is in danger of theft. So, there are lots of ways to prevent USB ports, especially there are 3rd party fancy paid or free apps. But you can do this in just 1 minute. Just open the registry editor by typing “regedit” to run. Open the following path.

“HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet \Services\UsbStor”

In the right pane, double click on the “Start” and type “4″ in the Value field. That’s all. If you want to enable ports just change the value to “3″.
