Have you ever wished you could make your desktop windows see-through for a cleaner and more modern look? That’s exactly what Glass2k does. This lightweight utility allows you to make any window transparent on Windows 11, 10, 8, or 7 using just keyboard shortcuts. It’s simple, effective, and doesn’t require installation.
What is Glass2k?
Glass2k is a tiny freeware program designed to let users control window transparency on Windows operating systems. Once launched, it quietly sits in the background and allows you to adjust the transparency of any active window using keyboard shortcuts like Ctrl + Shift + (1-9). Each number key corresponds to a different transparency level — from fully opaque (0%) to fully transparent (100%).
If you enjoy customizing the look and feel of your Windows interface, you may also like to explore how to make Windows transparent through different freeware tools.
Key Features of Glass2k
Despite being a tiny portable tool, Glass2k offers several handy features for personalization and productivity:
- Adjustable transparency: Use quick hotkeys to modify opacity in real time.
- Auto-load settings: Save transparency preferences for each window.
- Portable: No installation required — just run the EXE and go.
- Lightweight: Consumes almost no system resources.
- Simple interface: Easy-to-understand configuration panel for hotkey management.
Windows already includes some basic transparency features, but they’re quite limited. For comparison, you can check how to enable or disable transparency effects in Windows 11 to see the visual difference.
How to Use Glass2k
Using Glass2k is incredibly simple:
Step 1. Download the Glass2k executable file on your PC.
Step 2. Launch the executable file — no installation needed.
Step 3. Press Ctrl + Shift + (any number 1-9) to adjust the transparency level of the currently active window.
Step 4. Press Ctrl + Shift + 0 to reset transparency to normal.
You can also configure Glass2k to auto-start with Windows and remember your last transparency settings. For even more aesthetic tweaks, learn how to make your taskbar transparent for a consistent design style across your desktop.
As mentioned earlier, once you launch Glass2k, it quietly sits in the system tray. Right-click on its icon and select Settings to configure it. You can set this tool to auto-load every time Windows starts, auto-remember every Windows’ Transparency Settings, and beep on glassification.
By default, the transparency pop-up is enabled when you right-click on any window. That means when you right-click on any window, the Glass2k transparency pop-up will open, and you can adjust transparency easily. Using the “Transparency Popup” drop-down, you can combine it with modifier keys.
This tool also allows users to change the transparency level of the Taskbar. Just drag the Taskbar Transparency slider to adjust how transparent your Windows taskbar appears.
Once you are happy with the configuration, click the Save button to apply the changes.
When Glass2k Can Help You
Glass2k is particularly useful for users who multitask frequently and want to keep an eye on multiple windows at once.

It’s also great for creating screenshots or video tutorials that showcase overlapping content neatly.
If you love desktop aesthetics, you can further personalize your system by customizing window borders and shadows or changing title bar text color for better visibility.
