I hadn't installed any updates the day I installed IE 10, but I found 3. I uninstalled IE 10, but it still didn't work.
Uninstalled a few applications I had installed in the past 2 days, still no goįinally I remembered installing the IE 10 preview, in the past 2 days, but it does not show in the add remove programs - it shows under installed updates. Tried killing all running process that I could. Installed all updated, which I was behind on: This didn't help either.
The repair utility still claimed that my graphics card doesn't support Aero
Updated the graphics drivers: didn't help. It did nothing and claimed that my video card (a Radeon 7970), which used to display Aero perfectly, isn't capable of supporting Aero. When this happened to me, I spent a little time searching, and found the above utility. Microsoft even has a little automated utility to try to help you fix it. A common recurring problem is when it stops working for no apparent reason.
It's not just eye candy, the Alt-Tab preview and the aero peek on the task bar are incredibly useful. Aero was a nice visual addition in Vista which also exists in Windows 7.
