First issue. Microsoft Silverlight keeps unhiding itself. I've hidden it at least twice since I reinstalled Windows 7 a few months ago and it's annoying.
Second issue. How do I prevent Windows Update from providing updates for software that isn't installed? I installed Microsoft office with only Word, Excel, Access, and Outlook yet it's displaying updates to PowerPoint and PowerPoint Viewer which I expressly did not install. Again, it's annoying to have to tick off updates to software that isn't even installed on my machine.
