Sojiro84: I agree, no effect in Win 10. I contacted support, got a reply, sent in my logs, and am hoping for a reply...
(Y'z shadow (freeware, old) works, but there's a problem with tiled (win 10) programs whereby it leaves blank frames. I've fixed that (sort of) with a small script which conditionally kills a Win 10 process, but it's not a complete or 'nice' solution, 'tho pretty good in practice).
