The user does not have the permissions required to create or modify registry keys.

Examples

This example sets the value FontColor to "red" in the key HKEY_LOCAL_MACHINE\Software\MyCompany\Preferences.

My.Computer.Registry.LocalMachine.OpenSubKey(
  "Software\MyCompany\Preferences", True)
My.Computer.Registry.LocalMachine.SetValue("FontColor", "red")

Remarks

If the specified key or value does not exist, it is created.

Here is an example of a task involving the My.Computer.Registry.SetValue method.
