TWCU.exe is a critical pogram for TP-LINK uses to connect to the internet.
   
This is needed for TP Link wireless cards. It is safe.
  Salvatore  
all ive noticed is as the process is running all of my games will minimize, as will some other programs, and it will bring me to the desktop, when i end the process this doesnt happen anymore..

Causes full-screen applications to lose focus. Killing this process won't stop your wifi from working.

TWCU.exe is TP Link's wireless configuration tool, a task windows can handle. This process intermittenly switches focus from open programs and minimizes fullscreen ones on my windows xp system

Everyone is right, it's for the TP Link wireless cards. But like other people have said it constantly minimizes games randomly and "clicks" out of applications at least once every 30 seconds. Just exit out of it and only use it when you need it.

Official TP Link software, but CAN still cause problems. It randomly makes windows inactive in Win 7, which hinders typing on a keyboard.

This program causes most of my other programs to lose focus every 15 seconds or so meaning if you are writing in word or an email it just stops until you re click the focus the cursor. I have to manually stop the program in task manager to stop it doing that

I have a TP-LINK wireless connecter and it is for that. However, it causes my game to minimize every few minutes. It can be killed and I can still connect to the internet.
   
Ruins any full screen application or game focus. brings you to desktop but is otherwise safe. Annoying but safe lol

Necessary for TP-LINK Wlan cards, causes programs to loose focus and minimise

Best practices for resolving TWCU issues

A clean and tidy computer is the key requirement for avoiding problems with TWCU. 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 TWCU.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.
