From Vadim Rozenfeld:

Below is my client machine settings. Please pay attention to 'edid=off'
It works fine with 'edid=on' (edid provided by qemu) but one of edid
related test will fail
Also, please pay attention that some of hv_xxx flags are off.

I used hck2004 from 
https://docs.microsoft.com/en-us/windows-hardware/test/hlk/
for hck 2004 we don't need any additional packages to be installed 
inside of client, except for office2013 (or it's open source
alternative Apache open office 
https://www.openoffice.org/download/index.html in case if you want to
run full test including interactive testing)

In case of hck1903 the following package 
https://go.microsoft.com/fwlink/?linkid=2087319 needs to be installed 
inside of the client.

I didn't try testing Win8 but IIRC it also requires additional graphic 
package to be installed.

change status to verified according to comment#3
