How to disable or enable USB Ports in Windows 7 | 8

How often you have witnessed blocked Pen drive or USB drive access in your work place or college or school? I believe many times; in fact every time you try to use the USB drive, you are not allowed, simply because the administrator has disabled USB drive detection on your PC. 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

There are three ways an administrator can prevent using of USB Drives.

They are:

  1. Altering registry values for USB Mass Storage Devices.
  2. Disabling USB Ports from Device Manager.
  3. 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.

  1. Go to Start > Run , type “regedit” and press enter to open the registry editor
  2. 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. 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.

4. Use USB Drive Disabler /Enabler.

You can download and use a free tool USB Drive Disabler / Enabler which will allow you to easily enable or disable USB drives on your Windows computer.

    oh, is it April 1 today ?
    what a joke…
    are you trying to get a new career in standup-comedy ?
    you have completely forgotten one VERY important thing,
    you won´t be able to use any of those solutions that you posted above without ADMINISTRATIVE rights to the computer.

  • Caleb

    @hackerman1 It goes without saying that you require admin rights.

  • Anonymous

    There is probably a very good reason why your USB stick does not work at school or work. It’s never a good idea to encourage others to steal let alone help them to accomplish this.

    Do you have any more “cracks” to share with us? Maybe a guide to install pirated copies of Windows or how to steal wifi from your friends?

    There is nothing illegal about this post imo. Most of this has been documented on the net, including Microsoft/KB article/s. The post attempts to show how you can disable AND enable USB drives.

  • Anonymous

    It’s more to do with ethics than legalities. This is the Internet where everything is documented and available, the question is where do you draw the line between acceptable or unacceptable?

  • Khan Azharuddin12345

    Hackerman1…. If you dont have Admin rights on your PC. that means you cant open Command Prompt..is that you mean to say.. ? You dont have to be genius to open command prompt( using notepad). And once you have command prompt you can do wonders out there.
    And I am not telling you how you do it but passing a hint your way
    ” net user ” command is sufficient to do the stuff you want..

  • Ankitkaulmachama

    Hi Azharuddin, You have mentioned about a method in which you are saying uninstall the USB Mass Storage Drivers. Now I just wanted to ask where I can find these drivers in case I feel I want to enable USB devices again?

    Can we find them online??

  • Khan Azharuddin12345

    Hi Ankitkaulmachama
    If you uninstall the USB mass storage drivers , You can install it from your mobo driver CD.. If you are looking online then just right click on the USB mass storage and click install.. If u are looking for drivers online you can find them quite easily…
    I would recommend you to disable USB drivers than un-installing the driver.. It will ease your work to make things back to normal…thanks
    hope that helps…

    There is one more thing that disabling USB ports altogether – especially on a laptop – that have: web camera, a wireless module etc. all these that are built-in accessories and very important are PHYSICALLY connected to their motherboard AS USB CONNECTIONS although if you look inside your laptop they don’t have USB type coupling!

  • Sukhpreet Singh

    Goto HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlStorageDevicePolicies then their create a new key and name it as ‘WriteProtect’ without quotes then set its value 1 to diable USB ports and By changing its value to 0 enable your ports . .

    Very interesting fact that by using this trick i.e. by setting value to 1 . . data can only enter into your computer !! If you want to copy data to pen drive , or hard disk external , memory card etc . . then windows will display message ‘Media Is write Protected !! ” , but still u can copy data from these devices to internal hard disk . . .by again setting value to 0 , , all become normal again :) sorry for bad english . . hope this works on your side :) im using this trick from 2 years :)

  • Ksdhf

    Well, interesting question, but I doubt it corresponds to you to draw that line for everybody.

  • Ashishmehtad

    I am using Dell Latitude.
    I have enabled USB port in Device Manager and changed regedit entries as well.
    I have the USB drivers but when I try to install them it fails saying some admin id is required, although I am admin user.This is because there is a file in C:WindowsSystem32driversUSBSTOR.SYS
    which has to be modified so that I can modify the user rights to Full Control, right now its Read Only, I cannot do this as well.
    I have tried pasting this file from some other machine but it does not allow me to paste any data, giving permission error.
    Any way out ?

    Hello to everybody. Is it possible to disable/enable specific usb ports? One more question: is it possible to disable usb ports only for storage devices but to be fully functional for other devices like scanners and printers?

  • Rockstar

    I tried all the 4 ways to enable USB port; but still it didn’t work on my office laptop. On re-installing driver it opens up the access and immediately automatically port gets disable. Could you please suggest something on this?

  • Dale

    My USB quit working 6 months ago, I sent my netbook to Acer for repair. Acer changed the motherboard, but did not test the usb ports. They still did not work. I reinstalled Win 7 from the other section of my hard drive to no avail. It sure seems that this is a Windows problem, but microsoft will not help because this is OEM software, and I really think that Acer is brain dead on this problem. If anyone can help please contact me. ddugard@gmail.com

    The first 2 ways of disabling USB port is excellent and i personally used and gave tips to many. Un-installing he USB device driver is a foolish. People may also use the 3rd way but not necessary to install another software or tool for doing this.

  • ProtectandAccess

    I read all the 4 ways to disable USB port. Except procedure 4 i have tried all others and i am successful in all the cases. This USB disable feature is extremely useful for data security. Common users have no idea about this. So your data is safe from others.

  • Kevin

    This doesn’t stop stealing or hacking. I find it funny that they disable USB ports and yet you still have access your your online cloud storage spaces. It just shows how system admins are so behind in times.
    Not to speak that it is not hard at all to get Administrator access on a computer. Specially when the System Admins just disabled the Administrator on the computer in question.

  • Kevin

    There is nothing unethical in writing and posting about how to get around device’s security. It is ethical in sharing information, so that we can learn how something works and then learn to either fix them or question our perspective of the purpose/s of restricting. Specially when people have better ways of getting around the “security” like using cloud storage.
    Another security that we post online to get around is the unrooted Androids. The only true argument that you can stand on for unrooted Androids is to protect users from ourselves. But cases like the AT&T Galaxy Note 3 GPS, there is a real need of rooted device, As well as many other reasons for rooting Androids,
    Learning and educating on how to get around security is no unethical and it has its place being posted online.

    The UniBlue advertisement is bad news. Don’t fall for it. Should be taken down from this site. Just saying.
