The genuine wlanext.exe file is an important part of Windows – it’s a system process that is designed to host multiple Windows services. It’s an essential implementation on all recent Windows versions – several services can use wlanext.exe to share a process to reduce resource consumption. The wlanext.exe is also referred to as an Extensibility framework – an interface for wireless security and connectivity features on Windows. Wlanext.exe is is the executable that runs the framework, in case you’re dealing with the legitimate file. When it comes to the task it performs, it’s main roles is to serve as an interface for the drivers of wireless network adapters (integrated or coming from a USB, PCI or PCMCIA card).

Is Wlanext.exe safe?
While the genuine wlanext.exe poses no security threat whatsoever and it’s actually a crucial part of every recent version of Windows, not the same can be said about copycat malware that uses the permissions that wlanext.exe has to bury themselves deep into the system files to avoid being detected by security scanners. If you have two instances of the wlanext.exe file, chances are one of them is malware in disguise.

Because of this, it’s important to take the time and take the necessary steps to analyze the file before assuming that the file is a security threat or not. Keep in mind that the vast majority of successful malware have cloaking capabilities – meaning that they will deliberately seek files with enhanced permissions and take their form to avoid detection.

So if you only have one instance of the wlanext.exe file, removing it is not recommended under any circumstances. However, there is a scenario in which removing the file is acceptable. If you’re seeing two active wlanext.exe files in Task Manager and you verified that both are genuine, you can safely remove the one that is located outside C:\Windows\System32. That was probably installed by a third party utility, so removing it will re-direct the processes that are using the file towards the main one located in C:\Windows\System32.
