Activator is a lightweight application that can quickly minimise all inactive windows, leaving you with only the window you are using open. The intention here is to create a clean, distraction-free environment to work in with minimal effort on the part of the user.
The main attraction of Activator is one of convenience, since it doesn’t do anything you couldn’t do yourself, but it does do it more easily and quickly. You might consider combining Activator with something like Clean Master or Clean Space to create a truly clean desktop environment.
Lightweight and simple to use
Activator does not have any settings to worry about and does not take up any space in memory. This is because the app does not run constantly—it only runs when you launch it, whereupon it immediately minimises all of the windows that are not currently active (that is, the ones you are not currently using) and then closes itself.
This does mean that you will have to have a shortcut to the app to hand to make it useful, since having to go looking for Activator when you want to clean up the desktop will defy the point of the app. Unless you have dozens and dozens of windows open and searching for the app would still be quicker than minimising the windows manually.
Not a necessary application but can be useful
Few would call Activator a must-have app, since you would need to regularly have a lot of windows open to make it feel necessary. That being said, the app does not consume memory and takes up next to no space on your computer’s storage. You can also set up a macro to launch the app, making it able to be launched at the press of a key.
One thing to note about the app is that it can’t always close windows that don’t have a title, such as certain media player windows and apps with custom interface designs. This doesn’t affect many apps, but when the sole purpose of the app is to minimise windows, not being able to minimise some windows is a noticeable flaw.
