Unified Write Filter
The IPC Application Controller is protected with a Unified Write Filter (UWF). The UWF intercepts disk
changes and stores them into a memory overlay in RAM memory instead of applying them to disk. The
UWF ensures the integrity of the disk at system startup.
All changes made to the system will be lost at the next reboot. This includes installation of new soft-
ware, Windows updates and other software updates.
