How to Use GiliSoft Exe Lock to Protect Your ProgramsProtecting executable (.exe) files on Windows can prevent unauthorized use, tampering, or accidental deletion. GiliSoft Exe Lock is a lightweight tool designed to password-protect executable files so only users with the password can run them. This guide explains what Exe Lock does, when to use it, step-by-step instructions for setup, advanced options and best practices, troubleshooting tips, and alternative approaches for stronger protection.
What GiliSoft Exe Lock does (and what it doesn’t)
- What it does: GiliSoft Exe Lock prevents unauthorized execution of specified .exe files by requiring a password to run them. It can lock individual executables and maintain protection across reboots. Locked programs won’t launch unless the correct password is entered.
- What it doesn’t do: It is not an anti-malware product and won’t detect or remove viruses. It also doesn’t fully prevent a determined attacker with administrative rights or physical access from bypassing protection (for example by renaming, deleting, or copying files from Safe Mode or another OS). For enterprise-grade protection consider code signing, application whitelisting, or OS-level policies.
When to use Exe Lock
Use Exe Lock when you need a simple, quick way to:
- Prevent family members, coworkers, or students from running specific applications (games, chat apps, installers).
- Protect utilities or in-house tools on shared PCs without setting up full user account restrictions.
- Add a lightweight barrier against accidental execution of risky programs.
Do not rely on it as the only protection for sensitive intellectual property or critical system utilities.
Installing GiliSoft Exe Lock
- Download the installer from the official GiliSoft website or your organization’s trusted software repository.
- Run the installer as an administrator (right-click → “Run as administrator”) to ensure it can set required permissions.
- Follow the setup wizard: accept the license agreement, choose install location, and finish installation.
- Launch Exe Lock. On first run you may be prompted to set a master password — choose a strong password and store it securely (password manager recommended).
Basic usage — locking an executable
- Open GiliSoft Exe Lock.
- Click the “Add” or “+” button (label varies by version) and browse to the .exe file you want to protect.
- Select the file and confirm. The program usually lists locked items in its main window.
- Ensure lock status is enabled (a checkbox or lock icon). The program may ask for the master password to confirm.
- Test by trying to run the locked .exe — the launcher should prompt for the password or simply block execution.
Tip: If you want to protect multiple programs, add each .exe to the list. You can typically apply the same password to all of them.
Configuring options and behavior
GiliSoft Exe Lock often includes the following configurable settings (exact names may vary by version):
- Autostart protection: Enable the Exe Lock service to start with Windows so protections apply before users log in.
- Hide/Show GUI: Option to hide the Exe Lock interface so users can’t see which apps are locked.
- Protection strength: Some versions allow integration with system account controls or additional verification prompts.
- Notifications: Choose whether users see a password prompt or a generic “access denied” message.
- Backup/Restore config: Export the lock list and settings to a file so you can restore them on another machine or after reinstall.
Enable autostart and hide the GUI if you want minimal user awareness, but remember this also makes configuration harder for legitimate administrators unless you keep secure access to the master password.
Advanced tips
- Use a separate administrator account for managing Exe Lock settings so locked users cannot change protection.
- Combine Exe Lock with Windows user account restrictions: set locked users as Standard accounts, not Administrators, to reduce bypass risk.
- For portable apps, lock the launcher EXE rather than the portable executable files themselves.
- If you distribute protected in-house tools, consider code signing and a licensing system; Exe Lock is more of a client-side barrier than a secure DRM solution.
- Keep Exe Lock updated to the latest version to reduce exploitation risks from known vulnerabilities.
Common problems and fixes
- Locked program still runs: Check whether the user has administrative rights. If so, they may be able to disable Exe Lock or run the program from Safe Mode. Restrict admin privileges where necessary.
- Cannot add an .exe: Ensure Exe Lock has been run as administrator, and that the file isn’t in a protected system folder requiring elevated rights to modify.
- Forgotten master password: If Exe Lock provides no recovery, you may need to reinstall the software and reconfigure locks. Always keep a secure backup of passwords and export settings if supported.
- Conflicts with antivirus: Some AVs may flag Exe Lock as a potentially unwanted program (PUP) because it modifies program behavior. Whitelist it in your AV if you trust the source.
Security considerations and limitations
- Exe Lock is a deterrent, not an absolute safeguard. Users with physical access, administrative privileges, or booting from alternative media can bypass protections.
- Do not rely on Exe Lock to protect secrets within executables; code obfuscation, signing, and server-side controls are better for IP protection.
- Regularly audit locked program lists and access logs (if available). Rotate the master password periodically.
Alternatives and complementary tools
- Windows AppLocker / Software Restriction Policies — enterprise-level application control built into Windows (requires Pro/Enterprise).
- BitLocker or full-disk encryption — protects files if the device is stolen.
- File system permissions — use NTFS permissions to restrict execution access.
- Application virtualization and sandboxing — limits what a program can access even if executed.
Comparison (quick):
| Purpose | GiliSoft Exe Lock | AppLocker / SRP | BitLocker |
|---|---|---|---|
| Ease of setup | High | Medium–Low | Medium |
| Prevent casual use | Yes | Yes | No (protects at rest) |
| Enterprise-grade control | No | Yes | No |
| Protect against physical bypass | No | No | Yes (encryption) |
Example workflow for a small office
- Create an Admin account for IT staff and Standard accounts for users.
- Install and configure GiliSoft Exe Lock on shared workstations, add sensitive tools to the lock list.
- Enable Exe Lock autostart and hide GUI; store master password in company password manager.
- Combine with NTFS permissions to restrict file deletion and renaming.
- Schedule quarterly reviews to update the lock list and rotate the master password.
Final notes
GiliSoft Exe Lock provides a quick, user-friendly way to prevent unauthorized launching of Windows executables. It’s best used as part of layered protection: account management, file permissions, encryption, and enterprise application controls. For high-value or highly sensitive software, invest in stronger, server-backed licensing or OS-level restriction mechanisms.
