I do a lot meetings and training via Live Meeting. One thing that has irked me for sometime has been that when I share my desktop it goes into a Basic display mode and disables all the cool Aero features.
I’ve figured out a workaround to this. After you share your screen go the start menu and paste the following into the search box – Find and fix problems with transparency and other visual effects. If you have UAC on it will prompt you to click Yes. The next screen that pops up is a troubleshooter wizard shown below.
If you click next it will go through a process where it checks features and HW to see if Aero can run. If it worked prior to sharing in Live Meeting it should now work after you run it.
I haven’t found a method to save this theme or settings but each time I need it I run this tool and it gives me the ability to run Aero features!
