This can occur if you’re doing something else to manage the Start Layout **BEFORE** PolicyPak Start Screen & Taskbar Manager is involved.
In short, there are two categories of Start Screen items:
- Default Windows groups and applications, or groups and applications pinned by user;
- Applications pinned by Enterprise (regardless of the method they were added: MDM, Group Policy, import-startlayout script during OSD, etc);
Items that fall into the second category “Applications pinned by Enterprise” are wiped out when new layout is applied by PolicyPak Start Screen & Taskbar Manager.
