The genuine SignalIslandUi.exe file is a software component of Intel® Turbo Boost Technology Monitor by Intel Corporation.
“SignalIslandUI.exe” is one of two processes in Intel’s Turbo Boost Technology Monitor application, a desktop gadget for Win7/Win8 that displays the processor’s highest speed in the past one second. (The other is “TurboBoost.exe,” only visible in Task Manager when displaying “all users.”) Both are uninstalled if “Intel Turbo Boost Technology Monitor” is selected in “Uninstall a Program” from the Control Panel. If enabled, (consult the system BIOS), Turbo Boost itself is controlled by the OS and continues working without the Monitor. Intel declared End-of-Life for the Monitor in June 2014. It only works on Generations 1-3 of Intel® Core i5 and i7 processors, under x32 and x64 Windows 7 and 8, (but for Win8 only in legacy desktop mode). For other processors it can display incorrect speeds and should be removed. Intel Corporation is multinational, based in Santa Clara, CA, USA; it is the world’s largest, highest-valued semiconductor manufacturer.
SignalIslandUI stands for Processor Signal Display Island User Interface
