-// *** Documentation for OEM Installs ***
-//
-// A /oem install requires:
-//  * Per-machine install
-//  * Running as admin
-//  * Running in Windows audit mode (ConfigManager::IsWindowsInstalling())
-//  * Offline installer (determined in LaunchHandoffProcess())
-//
-// If the first three conditions are met, SetOemInstallState() writes the
-// OemInstallTime registry value, which is used by IsOemInstalling() along with
-// other logic to determine whether Omaha is running in an OEM install
-// environment. Other objects use IsOemInstalling() - not
-// ConfigureManager::IsWindowsInstalling() - to determine whether to run in a
-// disabled mode for OEM factory installations. For example, the core exits
-// immediately without checking for updates or Code Red events, no instances
-// ping, and persistent IDs are not saved.
