Blocking access to a pendrive (USB storage device) in Windows 10 is a simple process that involves modifying a few settings in the Group Policy Editor or Registry Editor. Both methods restrict users from accessing USB storage devices, ensuring data security and preventing unauthorized data transfers. Follow the steps below to secure your system.
How to Block Pendrive Access in Windows 10
Blocking pendrive access in Windows 10 can safeguard your computer from unauthorized access or data theft. The steps below will guide you through either the Group Policy Editor or the Registry Editor to effectively block USB storage devices.
Step 1: Open Group Policy Editor
Open the Group Policy Editor by typing "gpedit.msc" in the Run dialog box and hitting Enter.
The Group Policy Editor allows administrators to manage policy settings in Windows. It’s a powerful tool that helps enforce specific configurations on your system.
Step 2: Navigate to Removable Storage Access
Go to Computer Configuration > Administrative Templates > System > Removable Storage Access.
This path will direct you to the settings related to removable storage devices, where you can configure policies to block or allow access to USB devices.
Step 3: Enable Deny Access to Removable Storage Classes
Double-click on "Deny access to removable storage classes" and select the Enabled option. Click Apply and OK.
Enabling this policy setting will prevent all users on the system from accessing USB storage devices, effectively blocking any data transfer.
Step 4: Open Registry Editor (Alternative Method)
Open the Registry Editor by typing "regedit" in the Run dialog box and hitting Enter.
The Registry Editor allows you to modify registry keys and values directly, offering another method to block USB storage devices if Group Policy Editor is unavailable.
Step 5: Navigate to USBSTOR Key
Go to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesUSBSTOR.
The USBSTOR registry key controls the USB storage drivers. By modifying this key, you can disable USB storage device access.
Step 6: Modify Start Value
Double-click the "Start" value and change the data to 4. Click OK.
Changing the Start value to 4 disables the USB storage driver, preventing the system from recognizing USB storage devices.
After completing these steps, USB storage devices will no longer be accessible on your Windows 10 computer. Users attempting to access a pendrive will receive an error message, ensuring your system’s data remains secure.

- Use Group Policy Editor for an easier, more user-friendly approach.
