Block USB cable or card in your PC

Hi friends, some people don't want to put any usb of others in their pc cause these may have viruses. So i have A simple registry trick to block usb drives (plz do it with care) 1. Go to Start –> Run, type Regedit. 2. Go to HKEY_LOCAL_MACHINE\System\CurrentControlset\Services\USBStor 3. In the right panel, look for value start and have value as 0000000(3) 4. Double click on that and change that value to 4. You might be required to restart the PC, and then you are done with it, USB is now blocked. In case if you want to get the USB unblocked, just change the value again to 3. Enjoy.
