Problem

Solution
To set the value of a registry key, use the SetItemProperty cmdlet:
PS >(GetItemProperty .).MyProgram c:\temp\MyProgram.exe PS >SetItemProperty . MyProgram d:\Lee\tools\MyProgram.exe PS >(GetItemProperty .).MyProgram d:\Lee\tools\MyProgram.exe
To remove the value of a registry key, use the RemoveItemProperty cmdlet:
PS >RemoveItemProperty . MyProgram PS >(GetItemProperty .).MyProgram
Discussion
In the registry provider, PowerShell treats registry keys as items and key values as properties of those items. To change the value of a key property, use the SetItemProperty cmdlet. The SetItemProperty cmdlet has the standard alias, sp.To remove a key property altogether, use the RemoveItemProperty cmdlet.
As always, use caution when changing information in the registry. Deleting or changing the wrong item can easily render your system unbootable.
For more information about the GetItemProperty cmdlet, type GetHelp GetItemProperty. For information about the SetItemProperty and RemoveItemProperty cmdlets, type GetHelp SetItemProperty or GetHelp RemoveItemProperty, respectively. For more information about the registry provider, type GetHelp Registry.
