Installing drivers from .cab-file

Hello,

I own a Venue 11 Pro 7140, Servive Tag ***private info removed***. After installing Win10 I wanted to install the latest Win10-driver I have found on dell.com, a file called 7140-win10-A06-XNGHF.cab. But how to install the drivers? Depacking the content of the.cab-file does not help, there is not setup-file for installing the drivers. And the device-manager does not find any driver-files. What can I do, how can I install the newest drivers?

Regards, Michael
