On Windows 10, if a USB or another supported port is available on the computer, users can connect removable storage devices (such as USB flash drives, external hard drives, and other types of mass storage devices) to access or export data.

Although it’s a common practice to use removable drives, there are times when you may want to restrict access to these types of devices. For instance, you may want to disable access to prevent users from connecting foreign devices, which may contain malware that can harm the computer or make it more difficult to install applications from unknown sources.

Or if the device stores sensitive data, disabling read and write access to removable storage devices can help lock-down the system to stop users from trying to make a copy of certain information, improving security – even if the data is stored in the network.

Regardless of the reason, Windows 10 includes settings that allow you to disable access to all removable storage devices using the Local Group Policy Editor or Registry.

Windows 10 Home doesn’t include access to the Local Group Policy Editor, but you can achieve the same results by modifying the Registry.

Warning: This is a friendly reminder that editing the Registry is risky, and it can cause irreversible damage to your installation if you don’t do it correctly. It’s recommended to make a full backup of your PC before proceeding.

To prevent access to all removable storage, use these steps: 

  1. Open Start.
  2. Search for regedit and click the top result to open the Registry.
  3. Browse the following path:HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\WindowsQuick tip: On Windows 10, you can now copy and paste the path in the Registry’s address bar to quickly jump to the key destination.

After you complete the steps, users will no longer have access to available removable storage devices, nor will they be able to connect external storage drives.

You can always undo the changes using the same instructions outlined above, but on step No. 4, make sure to right-click the RemovableStorageDevices key and select the Delete option. If you have other settings configured inside the key, don’t delete it. Instead, double-click the Deny_All DWORD and change the value from 1 to 0.

After undoing the changes using either method, you should regain access to storage devices immediately. However, if this is not the case, then reboot the device to refresh the changes.
