I respect this decision has to be taken. As has been mentioned above, MS announced the EOL of Win 7 a long time ago.
My hope is that programmers are going to be able to deliver significant improvements to the product and technology based on what Win 10 offers. If that’s the case then must be a correct decision. We’re all kind of at the mercy of the big tech companies but we’ve all also decided we want to use this program and technology so the vendors do set the rules. I don’t say I “like” this situation, but we are where we are, and we use what we use. All in all, it seems development is going in the right direction for the most part – issues known and unknown notwithstanding.
I’ve not yet “converted” to Win10 and I’m suffering version lag syndrome at the moment, but that’s OK. The win 10 conversion and update to Cubase Pro 10.5 is on the horizon.
