Unfortunately - I did. On my work machine, I have visual studio 2005 and 2008 versions installed. That's because I have to support products under both environments. Last night, windows update tried to install "security updates" (without any explanation of what they would be) - as I allowed my machine to download and install every night automatically.
The result - a messed up installation setup, and a completely wasted day just trying to fix the installation by "reinstalling" visual studio components. It's amazing that they push "security updates" to development applications, which I can't imagine why anyone would need these updates - while not auto-updating or even bothering to fix real bugs which cause visual studio 2008 to crash or get stuck, for example:
Visual studio 2008 sp1 hangs frequently when using XAML designer
Was the solution "auto-updated"? Or even mentioned anywhere on MSDN?! No! You'd have to dig for it in blogs and support forums:
Finally: CLR Hotfix Available for Visual Studio 2008 Rapid-Crashing
Microsoft Connect: Download hidden hot-fix to "Visual Studio rapid-crashing with no Dr Watson dialogs etc when working with XAML, seeing CLR fatal execution errors in the event log when this happens"
Auto updates are causing me to waste a day because of the following issue:
Blend 2 opens VS 2005 instead of VS 2008
Perhaps all we need to know about Microsoft can be learned from the following videos of its current CEO
Windows 1.0! WOW!!!
