Overlay Optimizer
Overlay Optimizer is a software component that works with Microsoft Unied Write Filter (UWF). Overlay Optimizer provides write
protection and extends the uptime of devices. Overlay optimizer works on the Windows 10 IoT Enterprise operating system.
The UWF protects the disk by storing the changes in the RAM overlay. When an application tries to write data to the disk, the write lter
redirects the write operations to the RAM overlay. The overlay size is precongured and cannot increase dynamically. When the overlay
runs out of space over a period, the device restarts.
The Overlay Optimizer monitors the UWFs' overlay space and the content. Overlay Optimizer identies higher overlay space consumption
in write lter and moves the unused content to the Overlay Optimizer's disk overlay. Clearing the UWF overlay extends the device uptime.
