How To: Exploring .wim files

As [almost] everybody knows, .wim files are in fact backup files for Windows (Windows Imaging Format), managed by the Windows 7 and Windows Server 2008.
These files are created when restore points are made by you or any system installing utility, or may come as restore/repair DVDs for your brand (Dell, Fujitsu, etc) computer.

But sometimes is useful just to explore those files and not install them.

The simplest method is to open these files with 7-Zip (4.49 and above).
Just open them as a simple archive files and you can explore and EXTRACT files you want (drivers, tools, etc).

I hope this trick will help you when in need.
