The Windows Integrity levels define different levels of trust-worthiness for applications and programs running at different levels of secure access. Most applications in Windows 10, 8.1 and other Windows OS run at a standard user level of access at the medium integrity level. Applications and Programs at the medium integrity level do not experience any restrictions on how they interact with other applications and with data at the medium integrity level. Specific tasks, programs, services or applications that require the administrative rights run at a full and high integrity level for Windows. In the most case the Windows system services run in system integrity level, this is so because there are restrictions on their ability to interact with the default desktop, and they often run with powerful system privileges.
