Gray unavailable Windows Installer programs Start Menu shortcuts
User Configuration\AdministrativeTemplates\Start Menu & Taskbar
Displays Start menu shortcuts to partially installed programs in gray text.
This policy makes it easier for users to distinguish between programs that are fully installed and those that are only partially installed.
Partially installed programs include those that a system administrator assigns using Windows Installer and those that users have configured for full installation upon first use.
If you disable this policy or do not configure it, all Start menu shortcuts appear in black text.
Enabling this policy can make the Start menu slow to open.
