If there is a polarized group, it's the Win 10 pros and cons. Everyone I know upgraded without a hitch. Even under prior Windows versions, I had the occasional shut-down issue. On my machine, you can just hold down the power button for a few seconds. Often the restart worked. I also shut mine down every night, unless I have a render running. That seems to keep it happy. All I can really offer is sympathy. System and software issues are the most frustrating, while you wait hours scouring the 'net for possible fixes, reading forums, trying to find something current . . .

Thanks for the clarification.  I do a lot of photography that doesn't end up looking like photography, and 3D that I take into software and continue to work on, so the edges become blurred.  But if it starts as a render, I'll call it 3D.  My favourite season; I hope I have time to come up with something. 

Sorry if this is a totally stupid question, but can someone explain the 2D and 3D difference to me?  Once you render a 3D you have a 2D image, right?  So . . . ???  Is 2D something that's created with other than 3D software. 

For that matter, if it started as a photograph but is now a work of art that doesn't resemble photography, does it still go in the photography category?

Thanks!
