Alt Tab has always been a method to switch between separate programs. Recently, Windows introduced a feature that enables switching between the last 3 tabs in each browser window.

As you can imagine, this causes a significant amount of bloat in the window switcher if you use 20-30 tabs.

Luckily, you can disable this feature with Intune (native CSP not created yet).

  1. Create a .ps1 file with the following contents

# Start logging
$stampDate = Get-Date
$scriptName = ([System.IO.Path]::GetFileNameWithoutExtension($(Split-Path $script:MyInvocation.MyCommand.Path -Leaf)))
$scriptFriendlyName = "ShowAllNotificationBar"
$logFile = "$env:ProgramData\Intune-PowerShell-Logs\$scriptFriendlyName-" + $stampDate.ToFileTimeUtc() + ".log"
Start-Transcript -Path $LogFile

### INSERT SCRIPT HERE ####

New-ItemProperty -LiteralPath 'HKCU:SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced' -Name 'MultiTaskingAltTabFilter' -Value 3 -PropertyType DWord -Force -ea SilentlyContinue;


### END SCRIPT HERE ###

# Stop transript
Stop-Transcript

2. Create a powershell script through Devices > Scripts > Add

3. Set the script settings to run with the logged on credentials as the registry key is HKCU.
