Overlay Optimizer Overlay Optimizer is a software component that works with Microsoft Unified 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 filter redirects the write operations to the RAM overlay. The overlay size is preconfigured 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 identifies higher overlay space consumption in write filter and moves the unused content to the Overlay Optimizer's disk overlay. Clearing the UWF overlay extends the device uptime. For more information, see Overlay Optimizer Release notes at https://downloads.dell.com/wyse/. Dell Secure Client Dell secure client is a security software for Windows-based thin clients.
