I noticed this update in Windows Update, and while it's fairly old ... it's still in Optional. It was never promoted to Important (Important or even Recommended). This usually means I skip it.

But I took a closer look and read the KB article. Looks fairly major (core changes). Also, did some Goggle-ing.

1. Is everyone installing it? Anyone else still have it un-installed?

2. Is it potentially only a problem for laptops (or AIO desktops with hybrid video)?

3. What are the ramifications of not installing it?
- I'm not seeing any so far. However, this machine is still on IE-9.
