Test-Confirm-No-fails.ps1

<#
	This script creates the registry key "HKCU:\77eeaf81-0b82-4b2e-93f3-ce464d61b955"
	with the property "p1". The GUID is generated, presumably such a key should not
	exist before the test.

	Remove-ItemProperty -Confirm is invoked in order to remove the property "p1"
	When the prompt is shown answer 'No', i.e. type 'n' and Enter.
	As a result, Remove-ItemProperty fails.

	The test registry key is removed after the test.
