How To Restrict Access To Drives In My Computer In Windows

If you have a shared or public computer that several people use, you might want to restrict access to it’s drives to prevent users from deleting important data. Today we look at restricting access to some or all drives on the machine using Local Group Policy.

Note: This method uses Local Group Policy Editor which is not available on home versions of Windows 7 or Vista

First type gpedit.msc in the search box of the Start Menu and hit Enter.


Now navigate to User Configuration \ Administrative Templates \ Windows Components \ Windows Explorer. Then on the right side under Setting, double click on Prevent access to drives from My Computer.


Select Enable then under Options from the drop down menu you can restrict a certain drive, a combination of drives, or restrict them all. The main drive you would probably want to restrict is the C:\ drive or which ever lettered drive Windows is installed on. Restricting all drives means they can’t access the CD or DVD drive, and cannot use a flash drive if they need to get files from it.

Note: This setting won’t prevent users from using programs that access the local drives.


The restrictions take effect immediately, no restart is required. When a user opens up My Computer they’ll be able to see which drives are listed, but when they try to access a restricted drive, they’ll get the following error message.


For the screenshots in this tutorial we used Windows 7 Ultimate, but this process also works with XP Professional and Vista (not in Home versions) the screens just look different.


Local Group Policy allows you to customize several settings for how you want to administer your machine. Restricting access to certain drives in addition to other security and access measures, can help  keep a shared computer stable and secure.

    This dosn’t stop access to programs or files when you know where they are, but it makes doing things like opening files or saving them to a different location much more error prone than it should be. So it’s a minor speed bump for the people who can do some damage, and a frustrating headache for the less experienced.

    For me it does not work properly.

    If I use these group policy even the Administrator no longer have access.

    What am I doing wrong?

    it is a good approach. but an unwanted user can change the setting again n can access the drive.
    what in that case?

    Hi Guys

    This not good policy , i created this to some admin users they are resbonsible of installing software

    i wanted to prevent them to copying files inside program files , but this policy has a gap !! what is this?

    they can login with any normal user and when UAC asks for username and passord then it will work

    with this administrator.

  12. Jyri Aikola

    Is there a way to do this so that it only applies to some accounts? If i do this it also blocks the admin account from using the files and folders.

  13. Prabhu.Rajan

    Thanks for the useful information.

    Any way we can Prevent the access of the predifined drive only. How can we prevent the access the other than the predefined drives in the GPO.

  14. Manna

    You could use User confog->Adminstrative templates->Windows Components and restrict access to drives that aren’t predefined like USB.

    @Jyri: to exclude adminstrators from being restricted access, make a security group for users you wanna restrict access to, add all the users (that you wanna restrict to this group) and set the gpo in such a way that it applies only to this security group and no one else.

  15. Manna

    The emntioned method works on the local security policy hence the case where administrators are also being restricted access

  16. Daniel Prince

    I do not find Windows Explorer in Windows Components!! What should I do? :(

  17. Daniel Prince

    And this is applicable foe which type of Users?

  18. Dan Krajewski

    You can hide or restrict any combinations by editing the ADM file to show more options like restrict H:
