Problem
You want to add a new key value to an existing registry key.
Solution
To add a value to a registry key, use the NewItemProperty cmdlet. Example 182 adds MyProgram.exe to the list of programs that start when the current user logs in.

Discussion
In the registry provider, PowerShell treats registry keys as items and key values as properties of those items. To create a key property, use the NewItemProperty cmdlet.
For more information about the NewItemProperty cmdlet, type GetHelp NewItemProperty. For more information about the registry provider, type GetHelp Registry.
