3 Detailed Ways to Disable Access to Removable Storage Devices

Restricting access to removable storage devices is crucial for computer security. This MiniTool guide details three methods to disable access to these devices on Windows 10/11.

Why Disable Access to Removable Storage?

Your computer's USB ports connect various peripherals, but unrestricted access can lead to malware infection or data breaches. Disabling access prevents unauthorized data transfer and malware installation.

Three Methods to Block Removable Devices:

1. Local Group Policy Editor:

This method offers a centralized way to manage settings. However, it's only available on Windows Professional and Enterprise editions.

• Step 1: Press Win R, type gpedit.msc, and click OK.
• Step 2: Navigate to Computer Configuration > Administrative Templates > System > Removable Storage Access.
• Step 3: Double-click All Removable Storage classes: Deny all access.
• Step 4: Select Enabled and click Apply and OK.

2. Registry Editor:

Modifying the registry directly achieves the same result, but requires caution. Always back up your registry before making changes.

• Step 1: Press Win R, type regedit.exe, and press Enter.
• Step 2: Navigate to HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindows.
• Step 3: Create a new key named RemovableStorageDevice.
• Step 4: Create a new DWORD (32-bit) Value named Deny_All and set its value data to 1.
• Step 5: Restart your computer for the changes to take effect. To re-enable access, change the value data to 0.

3. Device Manager:

Device Manager allows granular control over hardware. Caution: Disabling the wrong USB controller can affect essential devices like your keyboard and mouse. Consider creating a system restore point beforehand.

• Step 1: Right-click the Start menu and select Device Manager.
• Step 2: Expand Universal Serial Bus controllers.
• Step 3: Right-click on the USB ports to disable and select Disable device.
