Denk mal hängt mit dem usb wlan-stick zusammen
Config-Programm für die IEEE 802.11g Wireless Card von TrendNet Revision A
The application failed to instalize properly (0xc0150002).
WLAN Konfigurationstool, wer sich mit dem Windowseigenen Tool mit seinem WLAN verbindet, braucht diese Software nicht. Für ping-relevante Anwendungen wie Voice oder Online-Computerspiele sollte das Herstellertool dem windowseigenen Tool bevorzugt werden, da das windowseigene Tool regelmäßig kurze Aussetzer macht, um nach neuen WLAN-Netzwerken zu suchen.

Best practices for resolving WlanCU issues

A clean and tidy computer is the key requirement for avoiding problems with WlanCU. 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 repairing of your installation or, for Windows 8 and later versions, 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 WlanCU.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.
