Restrict access to USB drives
There are three ways an administrator can prevent using of USB Drives.
They are:
Altering registry values for USB Mass Storage Devices.
Disabling USB Ports from Device Manager.
By Un-installing the USB Mass Storage Drivers.
Lets us look at how we can fix these problems and enable USB on Windows 7 PC.
1. Disable or Enable USB Mass Storage Devices using Registry.
If the administrator is smart then he would definitely do this to ensure a tight blockade. He would alter the settings through regedit command on run console. Now how do you unlock it ? You have to go right into where the administrator has been. Here is how.
Go to Start > Run , type “regedit” and press enter to open the registry editor
Navigate to the following key
HKEY_LOCAL_MACHINE\SYSTEM\Curr
In the right pane, select Start and change the value to 3. (The value 4 will disable USB Storage). Click OK. This will re-enable USB Ports and allow you to use USB or Pen drives.
2. Disabling USB Ports from Device Manager.
If you still don’t find your USB drive working, you may have to look into the Device Manager. The Administrator could have possibly disabled the USB port here. Check out for any possibility in the Device Manager and enable the disabled port by right clicking on selected one and click Enable.
3. By un-installing the USB Mass Storage Drivers.
If the authorities are really worried about security in the school they would take the extreme step of un-installing the USB Mass Storage Drivers. To make things work, just install the device drivers. Here is how you do it.
As when you plug-in your USB drive, Windows will check for drivers, if not found Windows will prompt you to install the driver. This would definitely unlock the Pen drive at your School or office.
