Repugnant! Flash Disk Can Compromise Your Data – Here’s How to Protect Windows 11

Optimal Implementation:

1. Enable the option: “Prevent installation of devices not described by other policy settings.”
2. Combine it with the whitelist ID in point 1
3. Result:
   • Devices on the whitelist → Allowed to use
   •  Unknown device → Auto blocked

Method 2: Block USB via Registry Editor – The Ultimate Solution for Windows 11 Home!

For Windows 11 Home users, the Group Policy Editor feature is not available. But don’t worry, you can still block the USB port by modifying the Windows Registry. This method is quite effective, but it needs to be done carefully to keep the system stable.

Why Choose This Method?

• The only solution for Windows 11 Home (which doesn’t have a Group Policy)
• 100% effectively blocks all USB storage
• No additional software – purely Windows features

Step by Step Block USB via Registry Editor

1. Open the Windows Registry Editor

• Press Win + R → type “regedit” → Enter
• Click Yes on the UAC alert

2. Navigate to the USB Policy directory

Navigate to the following locations:

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows

3. Create a DeviceInstall folder

• Right-click Windows > New > Key → name: “DeviceInstall”
• Enter a new folder, create  another key named: “Restrictions”

4. Create a DenyRemovableDevices key

• Inside the Restrictions, right-click the empty area
• Select New > DWORD (32-bit) Value
• Name: “DenyRemovableDevices”
• Double-click, set value:
  • 1 = Total block
  • 0 = Allow access

5. Restart

Press Win + R → type “shutdown /r /t 0” → Enter to restart super fast

Did you know that all the manual steps can be shortened to just 1 click? Here are the secrets that are rarely revealed!

How This Magic Script Works:

A REG file works like a “registry action shortcut” – when executed, it will:

1. Automatically create all necessary folders and keys
2. Set the DenyRemovableDevices value  to 1
3. Without the need to open the manual Registry Editor

How to Create a Magic File:

1. Open Notepad
2. Copy-paste this script:

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\DeviceInstall\Restrictions]
“DenyRemovableDevices”=dword:00000001

3. Save As → select All Files → name disable_usb.reg

How to Use:

• Double-click the disable_usb.reg file
• Click Yes on the security alert
• Boom! USB is blocked immediately after restarting
