ViewAllWindows

Even though there’s no active window on the desktop, it doesn’t mean there’s nothing running, or a window can’t be created or detected for an associated process. You might need this info in your developments, and you can definitely rely on specialized applications like ViewAllWindows in order to view and manage nearly all running instances on your PC.

All processes shown in a table layout

On the bright side of things, you don’t even have to go through a setup process to make the application work, so you can see what it can do for you as soon as it reaches your computer. It easily fits on a thumb drive in case you need to use it on other computers than your own, but you do need to be sure that .NET Framework is on your computer to ensure functionality.
All windows are detected as soon as the main window launches. Most of the space is used to display all detected items, finding them in a table layout with column headers for title, activation state, as well as window state, which can either be maximized or minimized. Sadly, the table doesn’t contain any grid lines, making it a little difficult to analyze items.

Minimize, close, maximize, and restore selected windows

Even some background processes have an associated window, or at least a class, and this application aims to show them all. Sadly, Explorer instances are difficult to detect, even close to impossible. Everything is shown according to window name.
Selecting a window lets you perform several operations, which can either be triggered through the context menu, or upper toolbar. These count as minimize, maximize, close, and restore. Unfortunately, no other window details are shown, such as objects or classes to help with programming projects.

A few last words

Bottom line is that you might lose track of window you work with, especially when having to deal with complex projects. One way to easily identify them is through ViewAllWindows, but it feels a little rough around the edges overall, showing even instances of windows which can’t really be made visible, but without any class info to help out.
