The code sample demonstrates how to start a low-integrity process. The application launches itself at the low integrity level when you click the "Launch myself at low integrity level" button on the application. Low integrity processes can only write to low integrity locations, such as the %USERPROFILE%\AppData\LocalLow folder or the HKEY_CURRENT_USER\Software\AppDataLow key. If you attempt to gain write access to objects at a higher integrity levels, you will get an access denied error even though the user's SID is granted write access in the discretionary access control list (DACL).

By default, child processes inherit the integrity level of their parent process. To start a low-integrity process, you must start a new child processwith a low-integrity access token by using CreateProcessAsUser. Please refer to the CreateLowIntegrityProcess sample function for details.
