For me this wifi adapter worked out of the box on Win10 and no additional software was required. A CD-ROM was included, but I didn't install it and didn't use it. Just plug it into a USB 2.0 port (not a hub), then go to network and internet settings and disable the built-in WiFi adapter (which stopped working properly), then enter the password for the router and it connected and showed 5 bars - just how the original WiFi worked. I think for me this is the perfect compromise between size and connected load.
