If multiple matches are found, the function prompts for a specific selection (one of which is 'all of the above'). .DESCRIPTION See .SYNOPSIS .NOTES .PARAMETER ProgramName This parameter is MANDATORY. This parameter takes a string that represents the name of the program you would like to uninstall. The value provided to this parameter does not have to be an exact match. If multiple matches are found the function prompts for a specfic selection (one of which is 'all of the above'). .PARAMETER UninstallAllSimilarlyNamedPackages This parameter is OPTIONAL. This parameter is a switch. If used, all programs that match the string provided to the -ProgramName parameter will be uninstalled. The user will NOT receive a prompt for specific selection. .EXAMPLE # Open an elevated PowerShell Session, import the module, and - PS C:\Users\zeroadmin> Uninstall-Program -ProgramName python .EXAMPLE # Open an elevated PowerShell Session, import the module, and - PS C:\Users\zeroadmin> Uninstall-Program -ProgramName python -UninstallAllSimilarlyNamedPackages #> function Uninstall-Program { [CmdletBinding()] Param ( [Parameter( Mandatory=$True, Position=0 )] [string]$ProgramName, [Parameter(Mandatory=$False)] [switch]$UninstallAllSimilarlyNamedPackages ) #region >> Variable/Parameter Transforms and PreRun Prep if (!$(GetElevation)) { Write-Error "The $($MyInvocation.MyCommand.Name) function must be ran from an elevated PowerShell Session (i.e. 'Run as Administrator')!
