A faithful preview of DeskWarden's real lock screen — not a mockup
Try it yourself

Windows never gave you this

Phones let you lock any app in two taps. Windows has nothing built in — and most third-party tools either cost money, need technical setup, or just hide a window instead of truly blocking it.

🧊

Kernel-level freeze

The process is actually suspended — not hidden, not minimized. It cannot open until unlocked.

🖱️

Zero setup

One double-click installer. No Python knowledge, no config files, no command line.

🪶

Genuinely lightweight

No Electron, no heavy runtime sitting in your taskbar eating RAM in the background.

🆓

Free, forever

No subscription, no account, no telemetry. Open source under the MIT license.

Real control, built into DeskWarden

Every app you protect gets its own rules — set once, enforced every time.

🔁

Four lock modes

Ask Always, Session Once, Always Block, or None — switch any app's behavior anytime.

🖥️

Fullscreen lock screen

Clean and unbypassable. Appears in under a second, every single time.

🚫

Three strikes and it's terminated

Three failed attempts and the app is terminated — no way to sneak around it.

🔐

SHA-256 hashing

Your master password is never stored in plain text, anywhere on disk.

💾

Backup & restore

Export your entire setup and bring it back after a reinstall in seconds.

📋

Security log

Every unlock and every failed attempt, timestamped and easy to review.

Looks the part of security software

A Control Panel that feels structured, and a lock screen that feels final.

Ready to take control?

Extract the zip, right-click install_deskwarden.bat, and run as administrator. DeskWarden installs Python if needed, sets itself up, and starts automatically.

Independent developer building practical Windows tools — DeskWarden started from wanting the same app-locking control on a PC that phones have had for years.
