Showcaser

Showcaser is a feather-light and simplistic application whose purpose is to showcase any active window by placing it on a white background which covers the entire screen.

This way, you can attract other people's attention to a specific window. It's practical to put together basic presentations from running programs.

The whole tool's wrapped in just one .exe file that you can copy to a preferred folder on the disk or on a removable storage device to be able to run Showcaser on any computer by just double-clicking it.

More importantly, it doesn't need DLLs or other components to launch, add new entries to the Windows registry, or create extra files on the disk. In order to uninstall it, you simply have to delete the .exe.

Once initialized, the app shows a very small panel on the screen that automatically lists the windows of all currently running processes, giving you the possibility to view their titles.

All you have to do is select a window from the list and showcase it with the click of a button. This triggers the utility to display a fullscreen white background, along with the specified window on top of it. The Escape key can be pressed to exit it. There are no other notable options provided by this piece of software.

Unsurprisingly, it left a small footprint on system performance in our tests, since it used low CPU and memory. Although it hasn't received updates for a long time, it worked smoothly on newer Windows editions without any compatibility issues, freezing or crashing.

Overall, Showcaser is plain and simple, enabling you to showcase any window by displaying it over a fullscreen white background. However, it doesn't have any configuration settings.
