Glass 2k is a little freeware application for Windows 2000 and Xp which you can use to add transparency effects to any window on your system. It remembers the changes that you make over sessions so that you do not have to make the modifications again.

The default keyboard shortcut to add transparency is CTRL + SHIFT + a key between 1 and 0 with 1 being transparent and 0 being the default value of all windows.

Glass 2k has to be loaded first for the transparency effects to become visible. It places an icon in the system tray which indicates that it is running. It is a good idea to load the program during windows start so that it applies the transparency effects to all windows automatically when you boot into your operating system.

The keyboard shortcuts can be changed to other keyboard combinations if you prefer that. Alternatively you can opt to add a Transparency Popup to the right mouse button which can be combined with a key as well.

Holding down the Alt-key and the right mouse button opens a slider that let you define the transparency level. Glass 2k can also set the transparency level of the task bar.

Please note that the program is only compatible with Windows XP and older versions of Windows, and not with newer versions such as Vista, Windows 7 or 8.

It is advised to have a capable video card to avoid slow downs and other issues while running the application. Make sure you have installed the latest video drivers as well.

Update: The program is not under development anymore and while it is working fine under Windows XP and Windows 2000, it is not compatible with newer versions of the Microsoft Windows operating system.

I suggest you check out GhostWin instead, which can also add transparency effects to any open window on your computer. The program is fully compatible with all recent versions of Windows so that you won't run into any compatibility issues using it.

    Yeah, Gatic you right. I used other program to make windows look tranparent and it’s good to show frieds, but not for everyday use. The only thing I prefer are xp-styles.

    This progrem came with the ‘Vista Transformation Pack’ (I forgot, was that talked about on Ghacks or not?), and it was cool for a while, but it was a resource hog, and I didn’t really like the transparent effect. It is cool if you want to show off, but it is not really practical for day-to-day use. At least that is how I felt.
