This is a great tip to disable usb storage drivers while allowing your keyboards, mouse and scanner to keep working. Very useful for public computers where you need to keep people away from copying its content. This only works on windows machine though.

The steps are as follows:
1. Click on Start and select Run. Type ‘regedit’ as shown in the picture below. This will bring up the registry editor

2. Export your registry backup in case you mess up anything. Its not really anything serious but at least you can bring back the settings in case you wander off from the guide.

3. Find the " HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USbStor" and change the key value ‘Start’ to 4

Value 4 - Storage USB devices are disabled
Value 3 - Storage USB devices are enabled
