How often have you witnessed blocked Pen drive or USB drive access in your workplace, college, or school? I believe many times; in fact, you are not allowed every time you try to use the USB drive, simply because the administrator has disabled USB drive detection on your Windows 11/10/8/7 system. Again, how often has your data been stolen because someone connected an unauthorized USB to your computer and copied your files? Well, you don’t need to worry because the solution to disable or enable USB Ports is pretty simple.
Restrict access to USB drives in Windows 11/10
There are several ways an administrator can prevent using USB Drives:
- Altering the Registry values for USB Mass Storage Devices.
- Disabling USB Ports from Device Manager.
- By Uninstalling the USB Mass Storage Drivers
- Using Command-line
- Using third-party freeware
- Using Microsoft Fix It.
Lets us look at how we can fix these problems and enable USB on a Windows PC.
1] Enable, Disable USB Drives & Mass Storage Devices using Registry
If the administrator is wise, then he would do this to ensure a tight blockade. He would alter the settings through the regedit command on the 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\CurrentControlSet\Services\USBSTOR
In the right pane, select Start and change the value to 3. (The value 4 will disable USB Storage). Click OK. It will re-enable USB Ports and allow you to use USB or Pen drives.
2] Disable 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 the selected one and clicking Enable or Disable, as per your requirement.

How to Disable USB Ports?
You can either do it from the UEFI or BIOS of your motherboard and the second way is to disable the USB driver using Group Policy or Software. Always make sure you remember how to roll back if you need it for urgent use. Also, note that Group Policy or Software works when you are inside the OS, but the motherboard method works right from the boot.
