apple.awt.UIElement, which allows for Java applications to prevent the application's icon from appearing in the Dock. A common use for this is when applications run in the system tray, but don't also want to show up in the Dock.
Similarly, on Windows there are a variety of features in scripting languages, such as [PowerShell](https://attack.mitre.org/techniques/T1059/001), Jscript, and [Visual Basic](https://attack.mitre.org/techniques/T1059/005) to make windows hidden. One example of this is powershell.exe -WindowStyle Hidden.(Citation: PowerShell About 2019)
The Windows Registry can also be edited to hide application windows from the current user. For example, by setting the `WindowPosition` subkey in the `HKEY_CURRENT_USER\Console\%SystemRoot%_System32_WindowsPowerShell_v1.0_PowerShell.exe` Registry key to a maximum value, PowerShell windows will open off screen and be hidden.(Citation: Cantoris Computing)
In addition, Windows supports the `CreateDesktop()` API that can create a hidden desktop window with its own corresponding explorer.exe process.(Citation: Hidden VNC)(Citation: Anatomy of an hVNC Attack) All applications running on the hidden desktop window, such as a hidden VNC (hVNC) session,(Citation: Hidden VNC) will be invisible to other desktops windows.
Adversaries may also leverage cmd.exe(Citation: Cybereason - Hidden Malicious Remote Access) as a parent process, and then utilize a LOLBin, such as DeviceCredentialDeployment.exe,(Citation: LOLBAS Project GitHub Device Cred Dep)(Citation: SecureList BlueNoroff Device Cred Dev) to hide windows.
