By default, Windows doesn’t save a history of USB storage connections.I built the raspberry pi/ASIC Block Erupter as recently in the news for fun.You can find these events in Event Viewer -> Application and Services Logs -> Windows -> Microsoft-Windows-DriverFrameworks-UserMode -> Operational.The Windows event log allows you to track events of connecting/ejecting USB drives. Status OK indicates that this USB drive is connected and working properly. In the screenshot below, I’ve created a RemovableStorageDevices key, and a subkey named You can create the specified registry keys and parameters manually. In the new registry key, you need to create a REG_DWORD parameter with the name of the restriction that you want to implement:ĭeny_Read - disable reading data from the media class ĭeny_Execute - denies running executable files from an external media class.ġ - block the specified type of access to devices of this class.To enable one of these policies, you must create a new subkey in the specified key with the GUID of the device class you want to block access to (column 2).All the above policies correspond to certain registry keys in the HKLM (or HKCU) \SOFTWARE\Policies\Microsoft\Windows\RemovableStorageDevices key (by default this registry key is missing). You can more flexibly control access to external devices by configuring the registry settings that are set by the policies discussed above via the Group Policy Preferences (GPP). Disable Access to USB Drives via Registry and Group Policy Preferences For this group, set permissions to read and apply the GPO, and leave only read permission for the Authenticated Users or Domain Computers group (by unchecking the Apply group policy checkbox).Īdd users to this AD group who need to block access to flash drives and removable USB disks. Create a security group “Deny USB” and add this group to the security settings of the GPO. There may be another task – you need to allow the use of external USB drives to everyone, except for a certain group of users. In the security settings editor, specify that the Domain Admins group is not allowed to apply this GPO ( Apply group policy – Deny). Go to the Delegation tab and click the Advanced.Add the Domain Admins group in the Security Filtering section.Select your Disable USB Access policy in the Group Policy Management console.For example, you want to prevent the USB blocking policy from being applied to the Domain Admins group You can use the GPO Security Filtering to make an exception in a policy. To enable this policy, open its properties and change from Not Configured to Enabled.Īfter enabling and updating the GPO settings on client computers ( gpupdate /force), the Windows will detect the connected external devices (not only USB devices, but also any external drives), but when trying to open them, an error will appear: Location is not availableĭrive is not accessible. You can implement the “strongest” restrict policy All Removable Storage Classes: Deny All Access to completely disable the access to all types of external storage devices.

Windows Portable Device – this class includes smartphones, tablets, players, etc.Īs you can see, for each device class you can deny the launch of executable files (protect computers against viruses), prohibit reading data, and writing/editing files on external storage.All Removable Storage: Allow direct access in remote sessions.All Removable Storage classes: Deny all access.Open the GPO management console ( gpmc.msc), find the Workstations container in the Organizational Unit structure, right-click on it, and create a new policy ( Create a GPO in this domain and Link it here).You can apply the USB restriction policy to the entire domain, but this will affect the servers and other technological devices. We are going to block USB drives on all computers in a domain OU named Workstations. You can block only USB drives, while other types of USB devices (mouse, keyboard, printer, USB to COM port adapters) that are not recognized as a removable disk will be available to the user. In Windows, you can flexibly manage access to external drives (USB, CD / DVD, etc.) using Active Directory Group Policies (we do not consider a radical way to disable USB ports through BIOS settings). Allow Only Specific USB Storage Devices in Windowsĭisabling USB Removable Drives in Windows with Group Policy.History of Connected USB Drives in Windows.
