Enable/Disable USB Drives By Making Changes In Registry

You can make changes in your Registry files to enable or disable the USB ports in Windows 7. Follow these steps:


Go to Start Menu, type “Regedit” in the Search box to open Registry Editor.

Navigate to this key – HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR

In the right-hand panel, look for Start and right click on it.

A sub-menu will appear, choose Modify
A small pop-up window will open, check if the value is 3.

 

If yes, then the port is already enabled. Change the value to 4 to disable the port.
Click OK to apply changes.
