Use GiliSoft USB Lock to allow only approved USB devices on Windows. Keep trusted company drives available while blocking unknown flash drives, external disks, and other removable media.
1. Install and open GiliSoft USB Lock.
2. Turn on USB storage restrictions for the PC or policy group you want to protect.
3. Add approved removable devices to the trusted-device list or whitelist.
4. Save the policy and confirm that only approved devices remain available.
5. Review blocked-device behavior and update the whitelist when hardware changes.
This page is ideal for offices, labs, and shared PCs where some USB devices must remain available but open access to all removable drives is too risky.
