function Remove-CCMCacheContent { <# .SYNOPSIS Removes the provided ContentID from the MEMCM cache .DESCRIPTION This function will remove the provided ContentID from the MEMCM cache. This is done using the UIResource.UIResourceMGR COM Object. .PARAMETER ContentID ContentID that you want removed from the MEMCM cache. An array can be provided .PARAMETER Clear Remove all content from the MEMCM cache .PARAMETER Force Remove content from the cache, even if it is marked for 'persist content in client cache' .PARAMETER CimSession Provides CimSessions to remove the provided ContentID from the MEMCM cache for .PARAMETER ComputerName Provides computer names to remove the provided ContentID from the MEMCM cache for .PARAMETER PSSession Provides PSSession to remove the provided ContentID from the MEMCM cache for .PARAMETER ConnectionPreference Determines if the 'Get-CCMConnection' function should check for a PSSession, or a CIMSession first when a ComputerName is passed to the function. This is ultimately going to result in the function running faster. The typical use case is when you are using the pipeline. In the pipeline scenario, the 'ComputerName' parameter is what is passed along the pipeline. The 'Get-CCMConnection' function is used to find the available connections, falling back from the preference specified in this parameter, to the the alternative (eg. you specify, PSSession, it falls back to CIMSession), and then falling back to ComputerName. Keep in mind that the 'ConnectionPreference' also determines what type of connection / command the ComputerName parameter is passed to. .EXAMPLE C:\PS> Remove-CCMCacheContent -Clear Clears the local MEMCM cache .EXAMPLE C:\PS> Remove-CCMCacheContent -ComputerName 'Workstation1234','Workstation4321' -ContentID TST002FE Removes ContentID TST002FE from the MEMCM cache for Workstation1234, and Workstation4321 .NOTES FileName: Remove-CCMCacheContent.ps1 Author: Cody Mathis Contact: @CodyMathis123 Created: 2020-01-12 Updated: 2020-02-27 #> [CmdletBinding(SupportsShouldProcess = $true, DefaultParameterSetName = 'ComputerName')] param( [parameter(Mandatory = $false, ValueFromPipelineByPropertyName = $true)] [string[]]$ContentID, [parameter(Mandatory = $false)] [switch]$Clear, [parameter(Mandatory = $false)] [switch]$Force, [Parameter(Mandatory = $false, ValueFromPipelineByPropertyName = $true, ParameterSetName = 'CimSession')] [Microsoft.Management.Infrastructure.CimSession[]]$CimSession, [Parameter(Mandatory = $false, ValueFromPipelineByPropertyName = $true, ParameterSetName = 'ComputerName')] [Alias('Connection', 'PSComputerName', 'PSConnectionName', 'IPAddress', 'ServerName', 'HostName', 'DNSHostName')] [string[]]$ComputerName = $env:ComputerName, [Parameter(Mandatory = $false, ParameterSetName = 'PSSession')] [Alias('Session')] [System.Management.Automation.Runspaces.PSSession[]]$PSSession, [Parameter(Mandatory = $false, ParameterSetName = 'ComputerName')] [ValidateSet('CimSession', 'PSSession')] [string]$ConnectionPreference ) begin { switch ($PSBoundParameters.Keys -contains 'ContentID' -and $PSBoundParameters.Keys -contains 'Clear') { $true { Write-Error -ErrorAction Stop -Message 'Both ContentID and Clear parameters provided - please only provide one.
