2. Fixes from Microsoft Fixes released by Microsoft to Original Device Manufacturer (ODM) Original Equipment Manufacturer (OEM) / Mobile Operator (MO) give additional applications to ODM OEM/MO decide whether to release update to their devices and customers Microsoft cannot dictate fix releases to OEM/MO

3. Operating System Upgrades Same story as Fix Releases Major cost to OEMs in releasing new OS on legacy devices
