I am another one very happy with Win 7, which I purchased when I was building a computer to run Poser and wanted to run 64bit.  Hated the look of Windows mobile 7 on the Nokia phones and Win 8 looks similar and just as awful.  So no update to Win 8 for me.  I am looking to build another PC in a the early part of 2013, again for Poser (2012) and it will be using Win 7 again.

 

 

I use Poser 13 on Windows 11 - For Scene set up I use a Geekcom A5 -  Ryzen 9 5900HX, with 64 gig ram and 3 TB  storage, mini PC with final rendering done on normal sized desktop using an AMD Ryzen Threadipper 1950X CPU, Corsair Hydro H100i CPU cooler, 3XS EVGA GTX 1080i SC with 11g Ram, 4 X 16gig Corsair DDR4 Ram and a Corsair RM 100 PSU .   The desktop is in a remote location with rendering done via Queue Manager which gives me a clearer desktop and quieter computer room.
