How to Lock Drive in Windows 11 Without BitLocker

Published by Nyau Wai Hoe - Updated on

BitLocker is a built-in tool in Windows that allows users to encrypt and lock an entire volume/drive with a password. You can read more about how to use BitLocker here: How to lock a drive or folder in Windows 11/10 with password. However, if you do not want to rely on BitLocker or any other software to lock your drive, this guide will show you a method on how to lock a drive by restricting users from accessing the drive via This PC or File Explorer without using BitLocker.

If you wish to hide your drive to prevent other users from even knowing that the drive exists (hiding the drive entirely from File Explorer), we recommend this guide instead: How to Hide a Drive in Windows 11.

The screenshot below shows how it looks like when you try to access a drive after restricting it through the group policy editor. “Restrictions – This operation has been cancelled due to restrictions in effect on this computer“.

If you enable the “Prevent access to drives from My Computer” setting and restrict a drive, the drive, directory, folders and subfolders within it will not be accessible through This PC, File Explorer, Run dialog box or the Map Network Drive dialog.

The drive icon will still be visible in This PC. However, when a user double-click the drive, a message will appear explaining that a setting has prevented this action. If you wish to also hide the drive entirely from This PC, read: How to Hide a Drive in Windows 11.

Additionally, this setting does not prevent users from using other software or program to access the restricted drive. It also does not prevent them from using tools such as Disk Management to view and change the drive properties.
