Just installed 10049 and it only took 3 hours or so. It seems better than 10041 thus far. The only way to get this update was by joining the FAST ring.
The biggie for me is that it installed the Hi Def Audio for the chipset (OK - I forgot to disable onboard first). It does not truly detect the Asus DG card and actually broke the setup for it. A reinstall of the driver fixed that.
The ongoing question of how to have rounded edges persists. Some programs load as they did in 10041 and others are sharp cornered. An example of this is Media Monkey 4 versus 3. The latter version has the "old" look still, but not so for the update to 4. I wonder when we get the option back for what I'll call smooth edges for desktops.
