function Remove-RegKey { <# .SYNOPSIS Deletes the specified registry key from local or remote computers. .DESCRIPTION Use Remove-RegKey to delete the specified registry key from local or remote computers. .PARAMETER ComputerName An array of computer names. The default is the local computer. .PARAMETER Hive The HKEY to open, from the RegistryHive enumeration. The default is 'LocalMachine'. Possible values: - ClassesRoot - CurrentUser - LocalMachine - Users - PerformanceData - CurrentConfig - DynData .PARAMETER Key The path of the registry key to open. .PARAMETER Force Overrides any confirmations made by the command. Even using the Force parameter, the function cannot override security restrictions. .PARAMETER Ping Use ping to test if the machine is available before connecting to it. If the machine is not responding to the test a warning message is output. .PARAMETER Recurse Deletes the specified subkey and any child subkeys recursively. .EXAMPLE $Key= "SOFTWARE\MyCompany\NewSubKey" Test-RegKey -Key $Key -ComputerName SERVER1,SERVER2 -PassThru | Remove-RegKey -Force Description ----------- The command checks if the NewSubKey key exists on SERVER1 and SERVER2. When using the PassThru parameter, each key, if found, it emitted to the pipeline. Each key found that is piped into Remove-RegKey is deleted whether it it empty or has any subkeys or values. .NOTES Author: Shay Levy Blog : http://blogs.microsoft.co.il/blogs/ScriptFanatic/ .LINK http://code.msdn.microsoft.com/PSRemoteRegistry .LINK Get-RegKey New-RegKey Test-RegKey #> [CmdletBinding(SupportsShouldProcess=$true,ConfirmImpact='High',DefaultParameterSetName="__AllParameterSets")] param( [Parameter( Position=0, ValueFromPipeline=$true, ValueFromPipelineByPropertyName=$true, HelpMessage="An array of computer names.
