################################################################################ <# .SYNOPSIS Closes one or more webbrowser instances selectively. .DESCRIPTION Provides granular control over closing web browser instances. Can target specific browsers (Edge, Chrome, Firefox) or close all browsers. Supports closing both main windows and background processes. .PARAMETER Edge Closes all Microsoft Edge browser instances. .PARAMETER Chrome Closes all Google Chrome browser instances. .PARAMETER Chromium Closes the default Chromium-based browser (Edge or Chrome). .PARAMETER Firefox Closes all Firefox browser instances. .PARAMETER All Closes all detected modern browser instances. .PARAMETER IncludeBackgroundProcesses Also closes background processes and tasks for the selected browsers. .EXAMPLE Close-Webbrowser -Chrome -Firefox -IncludeBackgroundProcesses # Closes all Chrome and Firefox instances including background processes .EXAMPLE wbc -a -bg # Closes all browser instances including background processes using aliases #> function Close-Webbrowser { [CmdletBinding(DefaultParameterSetName = 'Specific')] [Alias("wbc")] param( ######################################################################## [Alias("e")] [parameter( Mandatory = $false, Position = 0, ParameterSetName = 'Specific', HelpMessage = "Closes Microsoft Edge browser instances" )] [switch] $Edge, ######################################################################## [Alias("ch")] [parameter( Mandatory = $false, Position = 1, ParameterSetName = 'Specific', HelpMessage = "Closes Google Chrome browser instances" )] [switch] $Chrome, ######################################################################## [Alias("c")] [parameter( Mandatory = $false, Position = 2, ParameterSetName = 'Specific', HelpMessage = "Closes default chromium-based browser" )] [switch] $Chromium, ######################################################################## [Alias("ff")] [parameter( Mandatory = $false, Position = 3, ParameterSetName = 'Specific', HelpMessage = "Closes Firefox browser instances" )] [switch] $Firefox, ######################################################################## [Alias("a")] [parameter( Mandatory = $false, Position = 0, ParameterSetName = 'All', HelpMessage = "Closes all registered modern browsers" )] [switch] $All, ######################################################################## [Alias("bg", "Force")] [parameter( Mandatory = $false, Position = 4, HelpMessage = "Closes all instances including background tasks" )] [switch] $IncludeBackgroundProcesses ######################################################################## ) begin { # query system for installed browser information $installedBrowsers = Get-Webbrowser # determine system default browser $defaultBrowser = Get-DefaultWebbrowser Write-Verbose "Found $($installedBrowsers.Count) installed browsers" Write-Verbose "Default browser: $($defaultBrowser.Name)" } process { function Close-BrowserInstance { param ( [object] $Browser ) Write-Verbose "Attempting to close $($Browser.Name)" # extract process name without extension for matching $processName = [System.IO.Path]::GetFileNameWithoutExtension($Browser.Path) # find and process all matching browser instances Get-Process -Name $processName -ErrorAction SilentlyContinue | ForEach-Object { $currentProcess = $_ # handle background processes based on user preference if ((-not $IncludeBackgroundProcesses) -and ($currentProcess.MainWindowHandle -eq 0)) { Write-Verbose "Skipping background process $($currentProcess.Id)" return } elseif ($currentProcess.MainWindowHandle -ne 0) { # attempt graceful window close for processes with UI [GenXdev.Helpers.WindowObj]::GetMainWindow($currentProcess) | ForEach-Object { $startTime = [DateTime]::UtcNow $window = $_ # try graceful close $null = $window.Close() # wait up to 4 seconds for process to exit while (!$currentProcess.HasExited -and ([datetime]::UtcNow -
