Normally when you start a program you will get a window popped open with an icon displaying on Taskbar. But do you know that you can actually make that window completely hidden? It could be useful in some cases where you need a program running at the background without people noticing it, such as a program hidden quietly recording what you do on your computer.
Let’s say you want to launch a program called MySpy.exe, and you want to launch it in hidden mode. And here is you can do very easily quickly with a PowerShell cmdlet called Start-Process with a Window Style switch set to Hidden.
Start-Process -WindowStyle hidden -FilePath myspy.exe
Once the program launched, you won’t see it from the Taskbar but only in Task Manager.
Cool, isn’t it?
