I recently upgraded from TC17 to 2016 Platinum Pro.
To familiarized myself with the newer format, I was running thru Don Cheke's liquid cylinder tutorial.
After setting up my user interface to my liking and running thru the tutorial to the rendering section, I had a windows update, after which my UI has totally changed!
1. All my displayed standard icons have been replaced with icons that I rarely use (roof wall modifier, underlay, hatch pattern creator, etc., etc.
2. The menu bar seems to have defaulted to the TC17 version. For example, the drop down pallets section is now icon listed in the View menu when it was listed in the Modify drop down (I think) under Pallets.
3. When I right click on the menu section, the Customize window lists multiple Customs Toolbars 1-20 in the various tabs, no specific groups as before.
This, added to my disappointment that lightworks is not included in the 2016 Platinum Pro without an add in is almost making me want to go back to the TC17 version. The reason I don't is that it is 32 bit and runs out of memory when rendering.
