@Jody Thornton thanks for the update. I have Windows 8 on another machine... not so bad... especially when I install ClassicShell for the Start Menu ;)
I had to pull back on the Vista/Server2008 Updates the other day. I use a program called Chief Architect, which had been working fine. I noticed when rendering 3D models, instead of taking 5 seconds, it was taking 50 seconds! I checked various other issues (video drivers, ram, background programs/services), but couldn't isolate it to anything. I restored to an April 2018 Backup (which did have the March 2018 patches/updates) and it went back to 5 seconds. So I suspect "something" happened in the April/May/June Patches (had not yet done July/August). If I have some spare time, maybe I'll read the various Patches and see if any of them could have impacted Video Card/3D Rendering.
