function Set-RegString { <# .SYNOPSIS Sets or creates a string (REG_SZ) registry value on local or remote computers. .DESCRIPTION Use Set-RegString to set or create registry string (REG_SZ) value on 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 Value The name of the registry value. .PARAMETER Data The data to set the registry value. .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 PassThru Passes the newly custom object to the pipeline. By default, this function does not generate any output. .EXAMPLE $Key = "SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce" Set-RegString -Key $Key -Value Notepad -Data "notepad.exe" Description ----------- The command Sets or Creates a registry value named Notepad on the local computer RunOnce key. The name of ComputerName parameter, which is optional, is omitted. .EXAMPLE "SERVER1","SERVER1","SERVER3" | Set-RegString -Key $Key -Value Notepad -Data "notepad.exe" -Ping Description ----------- The command sets or creates a registry value named Notepad on three remote computers local computer's RunOnce key. When the Switch parameter Ping is specified the command issues a ping test to each computer. If the computer is not responding to the ping request a warning message is written to the console and the computer is not processed. .EXAMPLE Get-Content servers.txt | Set-RegString -Key $Key -Value Notepad -Data "notepad.exe" -Force -PassThru ComputerName Hive Key Value Data Type ------------ ---- --- ----- ---- ---- SERVER1 LocalMachine SOFTWARE\Microsoft\Windows\CurrentVersion\Run Notepad notepad.exe String SERVER2 LocalMachine SOFTWARE\Microsoft\Windows\CurrentVersion\Run Notepad notepad.exe String SERVER3 LocalMachine SOFTWARE\Microsoft\Windows\CurrentVersion\Run Notepad notepad.exe String Description ----------- The command uses the Get-Content cmdlet to get the server names from a text file. It Sets or Creates a registry String value named Notepad on three remote computers. By default, the caller is prompted to confirm each action. To override confirmations, the Force Switch parameter is specified. By default, the command doesn't return any objects back. To get the values objects, specify the PassThru Switch parameter. .OUTPUTS PSFanatic.Registry.RegistryValue (PSCustomObject) .NOTES Author: Shay Levy Blog : http://blogs.microsoft.co.il/blogs/ScriptFanatic/ .LINK http://code.msdn.microsoft.com/PSRemoteRegistry .LINK Get-RegString Get-RegValue Remove-RegValue Test-RegValue #> [OutputType('PSFanatic.Registry.RegistryValue')] [CmdletBinding(SupportsShouldProcess=$true,ConfirmImpact='High',DefaultParameterSetName="__AllParameterSets")] param( [Parameter( Position=0, ValueFromPipeline=$true, ValueFromPipelineByPropertyName=$true, HelpMessage="An array of computer names.
