Perfectionists will always look into the slightest details and adjust them to their preferences. That goes double for those of them who use a computer on a daily basis.

When you lose yourself into a computer for hours on end, whether you are working or just spending quality time, the user interface will start getting boring at some point.

This is where operating system enhancements come in: wallpapers, themes, screensavers etc.

One of these small applications that will add a subtle touch of class to your system is Y'z Shadow.

This is a software which allows you to attach a drop shadow to the windows of all your applications.

Y'z Shadow doesn't require installation, but make sure to extract all its contents from the archive instead of running them directly.. It will still work, but you won't have access to the Settings menu.

Once you initiate the executable file, the software will automatically insert itself into the system tray. Enabling it will bring out the mentioned drop shadows to the windows.

If you go to Settings, you can change color of the shadow, as well as its length and depth (on top, left, right and bottom of the window).

Drop shadows can also be attached to menus in Windows (and also to the Start taskbar), while setting a transparency level and fade-in effect (optional).

Exclusions are possible by drag-and-dropping applications (up to 32) into Y'z Shadow.

To see the results, just hit the Apply button.

The software barely uses CPU and memory resources, and any modifications in Settings are made instantly.

In conclusion, if you want to add a little sophistication to your same old operating system, then go with Y'z Shadow. It's free!
