Gigabyte EasyTune5.exe overclock software for cpu

Startup Launcher GUI.exe is indeed a utility to monitor startups.

indeed seems to be easytune 5
Wireless-G Notebook Adapter driver. Linksys

It is an official program by Gigabyte for tuning their motherboards. Whilst not essential to Windows, you won't get the best out of the mobo without it. Simply deleting it is also risky, since it works with the BIOS. If you don't want it, uninstal it properly.

Belongs to Siemens Gigaset WLAN USB stick. Don't think its needed since nothing happens when I kill it.

EasyTune6: in C:\Program Files\Gigabyte\ET6, file size 219,656 (on disk 221,184) Part of the mother board CPU clocking utility, Run in bottom tray. Seems to be safe.
Related to Gigabyte Easytune.
Gigabyte, EasyTune, ..GUI
GUI.exe puts an icon for gigabyte easytune onto the system tray. Double-clicking on the icon launches easytune. So GUI.exe is an easytune launcher.
  Notim Portant  
Gui.exe is also the process for OMS-q Call loging program
Gigabyte. Flashes MB, unstable PC + BSOD's as result
on many pcs i deal with its for centrastage
  centrastage usr   (further information)
seems to run in tandem with stability.dll. i found when overclocking to the max it was gui.exe & stability.dll that protected the cpu, so if you like to overclock you need them, if you use standard settings you don't. chances are that on a gygbo you will overclock so install them anyway.
Avast found it when i clicked 4GB-RAMPatch by Sumon put it in Virus Chest. Location not visible.

Best practices for resolving Gui issues

A clean and tidy computer is the key requirement for avoiding problems with Gui. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic 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 resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off doing a repair of your installation, or in the case of Windows 8, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the Gui.exe process on your computer, the following programs have proven to be helpful: Security 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. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
