How to Disable/Enable a USB Drive Using the Registry
If you want to try disabling the USB drive through the registry, type “run” in the search box (though you can check out our guide on how to back up the registry first). When it appears, type regedit and the registry editor should appear. Navigate to the following directory in the registry editor:
In the pane on the right, double-click “Start” to open the “Edit DWORD (32-bit)” box.
The value data, by default, will be set to “3.” To disable USB storage, change the “Value data” to “4” and click OK.
To (re)enable the USB storage, change the value data back to “3,” and the USB storage will be enabled again.
Use the Device Manager to Disable USB Ports
Disabling the USB port through the device manager is also very simple. Right-click the Start menu, and then click Device Manager. When the window appears, click Universal Serial Bus Controller. (This is the last option in the list). You can also select the uninstall option of the USB flash drive. When someone inserts the USB flash drive, Windows will not be able to find the driver.
Disable USB Storage by Using the Group Policy Editor
To disable the USB storage by using the Group Policy Editor, open “Run.” Once it’s open, type
gpedit.msc. On the left pane click on “Computer Configuration -> Administrative Templates -> System -> Removable Storage Access.”
When you click on “Removable Storage Access,” new options will appear in the right pane. Look for and click on the options that say “Removable Disks: Deny execute access,” “Removable Disks: Deny read access,” and “Removable Disks: Deny write access.”
Click on each of them to configure them. After clicking one, a window should appear with the name of the option. On the left, there will be three options: not configured, enabled, and disabled.
Click “Enabled” to disable. If you change your mind and want to enable them again, select the “Not configured” or “Disabled” option.
Now that your operating system is safe from unwanted USB devices, what’s next?
