+- name: 'HKLM - Add atomic_test key to launch executable as part of user setup'
+  description: |
+    This test will create an "atomic_test" key under 'HKLM:\SOFTWARE\Microsoft\Active Setup\Installed Components' to launch calc by configuring an active setup executable and 
+    forcing to run active setup using the "runonce.exe /AlternateShellStartup" command. 
+    Without the "runonce.exe /AlternateShellStartup" command it would run during the next logon for each user.
+    
+    Note: If you logout before running the cleanup command, you will be required to go through the OOBE (out-of-box experience) setup sequence to log back in. 
+    The payload will only run once unless the cleanup command is run in between tests.

+  description: |
+    This test will add a StubPath entry to the Active Setup native registry key associated with 'Internet Explorer Core Fonts' (UUID {C9E9A340-D1F1-11D0-821E-444553540600}) 
+    Said key doesn't have a StubPath value by default, by adding one it will launch calc by forcing to run active setup using runonce.exe /AlternateShellStartup. 
+    Without the last command it will normally run on next user logon. Note: this test will only run once successfully if no cleanup command is run in between test.
