This program came with my alfa usb wi-fi adapter. Once installed, it caused my CPU to run at 80 to 90% busy constantly, which kept causing my CPU to overheat and force a system shut down. Uninstalled it and used the Windows XP wizard to install my wireless network instead. fixed the problem. The Alfa driver is good, but don't install their utility. Use the Windows network wizard instead.

It got installed as part of my wireless network card
Only what I see on my Task Manager and that it is operating like crazy even though I am not on wireless network and it slows everything else down
  Eliza Howarth  
i found it on D:\Program Files\EDIMAX\Edimax Wireless LAN\Utility
a raling RT2870 Wireless LAN Card
It's appeared on my system overnight and I have definitely done nothing to install or activate it. It opens itself again each time I close it. My virus scanner can't detect it but still rather worrying and I intend to find a way to uninstall it.

using 8 to 12% ofr system time so I just end process and system idle went up 98%
This process came from a network dish I installed. the process was overworking the cpu. Once I uninstalled the dish software, the process ended and my cpu idle temp dropped a remarkable 15C.
The error pops up if the user does not have Administrative rights. Give the user Full access to this file.

It was installed as part of my alfa usb wifi adapter. My notebook computer only has 1gb of memory and this program pushes memory and CPU to its limits. It is loaded even when adapter is not being used. You can use Task Manager to stop the process without any problems.
This is a driver for my wireless LAN card, seem to loose all it's processing's when wireless card is disabled.
Uses 4-5% CPU even when USB wifi is not inserted. Disabled by closing from taskbar icon

Best practices for resolving RaUI issues

A clean and tidy computer is the key requirement for avoiding problems with RaUI. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the RaUI.exe process on your computer, the following programs have proven to be helpful: ASecurity Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. BMalwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
