Hi Marek,

Which builds of the drivers are you trying? The master branch? The toolchain 
used by the public build VM is currently VS2015/WDK10 and IIRC that does not 
actually support building for Windows 7.
If you download the 8.2.1 drivers, do you see the same thing? Those should be 
ok because they build with VS2013/WDK8.0, which do support building for Windows 
7.

If you need to run master branch drivers on Windows 7 you can probably graft 
the 8.2 vs2013 scripts onto the master branch code and get something to build, 
but the intention is that master (or 9.0 as they will be when they are 
released) drivers will only support Window 8.1 onwards as this allows us to use 
newer kernel and storport/ndis features.

Cheers,

  Paul
