USB Locker for Windows

USB protection utility — quick summary

USB Locker is a lightweight Windows program designed to restrict access to removable storage by requiring a password. It runs without installation, makes no changes to system registries, and keeps the interface intentionally simple so users can secure drives quickly.

Supported storage media

• Memory cards (SD, microSD, etc.)
• External hard drives
• Thumb sticks and pen drives
• USB flash drives

How it runs and moves with you

• The program is portable: place it on removable media and run it from there without installation.
• No administrator rights are required to launch the application.
• Because it does not write to the Windows registry, removing the program is as easy as deleting its files.

Security controls and anti‑tamper measures

• The app lets you change the access password and hides certain configuration options to prevent casual tampering.
• To reduce brute‑force attempts, the program will close itself after three consecutive incorrect password entries.
• Only a subset of settings is concealed to balance ease of use with protection of critical options.

Interface and user experience

USB Locker presents a minimal, intuitive interface with the essential configuration options visible on startup. There is no separate help file included because the controls are straightforward and self‑explanatory.
