VBScript MinimizeAll Method

last modified April 9, 2025

The MinimizeAll method in VBScript is part of the Shell object. It minimizes all open windows on the desktop, simulating the Windows key+M keyboard shortcut. This method is useful for automation scripts that need to clear the desktop quickly. It requires no parameters and returns no value.

MinimizeAll affects all top-level windows except those with specific styles. It’s commonly used in system administration scripts and automation tasks. This tutorial covers MinimizeAll with practical examples to demonstrate its usage in various scenarios.

MinimizeAll Method Overview

The MinimizeAll method belongs to the Windows Script Host Shell object. It requires creating a Shell object instance before calling the method. The method has no parameters and doesn’t return any value. It immediately minimizes all open windows when called.

Key features include system-wide window management and simple syntax. It doesn’t affect windows marked as “Always on Top”. MinimizeAll works with both applications and Explorer windows. Understanding this method helps create desktop automation scripts.

Basic MinimizeAll Usage

This example demonstrates the simplest use of MinimizeAll to minimize all open windows. It shows how to create the Shell object and call the method. The script provides immediate visual feedback by minimizing windows.

basic_minimizeall.vbs

Set objShell = CreateObject(“Shell.Application”) objShell.MinimizeAll

Set objShell = Nothing

The script creates a Shell.Application object and calls MinimizeAll. All open windows will minimize to the taskbar. The method executes immediately with no confirmation dialog. This is the most basic form of window management in VBScript.

MinimizeAll with Delay

This example adds a delay before minimizing windows. It demonstrates combining MinimizeAll with other VBScript features. The script shows a message before performing the minimization.

delayed_minimize.vbs

WScript.Echo “Windows will minimize in 3 seconds…” WScript.Sleep 3000

Set objShell = CreateObject(“Shell.Application”) objShell.MinimizeAll

Set objShell = Nothing

The script displays a message and waits 3 seconds before minimizing windows. WScript.Sleep pauses execution for the specified milliseconds. This shows how to create timed automation sequences. The Shell object is created after the delay for efficiency.

Toggle Between MinimizeAll and UndoMinimizeAll

This example demonstrates toggling between minimized and restored windows. It uses both MinimizeAll and UndoMinimizeAll methods. The script creates a complete minimize/restore cycle.

toggle_windows.vbs

Set objShell = CreateObject(“Shell.Application”)

’ Minimize all windows objShell.MinimizeAll WScript.Echo “All windows minimized” WScript.Sleep 2000

’ Restore all windows objShell.UndoMinimizeAll WScript.Echo “Windows restored”

Set objShell = Nothing

The script first minimizes all windows, then waits 2 seconds before restoring them. UndoMinimizeAll reverses the effect of MinimizeAll. This demonstrates complete window state management. The sleep period makes the effect visible to users.

MinimizeAll in a Scheduled Task

This example shows MinimizeAll used in a scheduled task scenario. It includes error handling and logging. The script is designed to run at specific times through Task Scheduler.

scheduled_minimize.vbs

On Error Resume Next

Set objShell = CreateObject(“Shell.Application”) If Err.Number <> 0 Then WScript.Echo “Error creating Shell object: " & Err.Description WScript.Quit 1 End If

objShell.MinimizeAll If Err.Number <> 0 Then WScript.Echo “Error minimizing windows: " & Err.Description Else WScript.Echo “All windows minimized successfully at " & Now End If

Set objShell = Nothing

The script includes error handling for robust scheduled execution. It verifies Shell object creation before calling methods. Success or failure is logged with timestamps. This makes it suitable for unattended automation tasks. Error details help troubleshoot issues.

Conditional MinimizeAll Based on Time

This advanced example only minimizes windows during specific hours. It demonstrates combining MinimizeAll with time checks. The script makes decisions based on the current system time.

conditional_minimize.vbs

currentHour = Hour(Now())

’ Only minimize between 9 PM and 5 AM If currentHour >= 21 Or currentHour < 5 Then Set objShell = CreateObject(“Shell.Application”) objShell.MinimizeAll WScript.Echo “Nighttime minimization activated” Set objShell = Nothing Else WScript.Echo “Not within minimization hours” End If

The script checks the current hour before minimizing windows. Action is only taken during specified nighttime hours. This shows intelligent automation based on conditions. The time check prevents unwanted minimization during work hours. The approach can be adapted for various scheduling needs.
