How to disable or enable USB Ports in Windows

There are two simple ways for disabling or for enabling the USB ports in our PC. Those are:

1. Disable or Enable USB Mass Storage Devices using Registry.

If the administrator is smart then he would definitely do this. He would alter the settings through Registry Editor. Now how do you lock or 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





In the right pane, select Start and change the value to 3. Click OK. This will enable USB Ports and allow you to use USB or Pen drives. Or change the value to 4 and clock OK, this will disable USB ports

2. Disabling USB Ports from Device Manager.

Still don’t find your USB ports 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

Go to Start > Run and type ‘devmgmt.msc’ and
press enter to open device manager. Now look for ‘Universal Serial bus Controller’
Expand the list and find if there is any red colored cross and enable the disabled port by right clicking on selected one and click Enable.

3. Now the third method is to Disable or Enable USB Ports on your computer from BIOS. This is a RISKY method. You could do this when you do not want to share your data with any. Some problems may arise due to this. Some got problem like they cannot enter into Bios after doing this.Do at your risk.
