Set-ItemProperty

The Set-ItemProperty cmdlet changes the value of the property of the specified item. You can use the cmdlet to
establish or change the properties of items. For example, you can use Set-ItemProperty to set the value of the
IsReadOnly property of a file object to $True.

You also use Set-ItemProperty to create and change registry values and data. For example, you can add a new
registry entry to a key and establish or change its value.
