Ok, this is not Microsoft's fault, but it is a perfect example for the windows experience.
While working on a nasty IE JavaScript bug in my windows VM I kept getting an annoying popup saying: "SUN Java - Update available".
After clicking it away several times, I though "heck let's install it so it keeps quiet" and I clicked on the icon. After waiting several minutes for the installer to load data and seeing some of the nice progress bar, I got this wonderful message:
Warning: Operating system not supported! - Thank you for choosing Java (TM) ...
So the VM is running XP SP1 and Sun's update requires SP2. When I clicked away the failed installation, I got a nice error window saying:
Installation failed due to user aborting
Thanks for annoying me, keeping me from work for 15minutes, and in the end blaming me for not be able to install ...

Microsoft has a similar ‘feature’ which pops up saying you require updates that need to restart the computer. If you catch the warning real quickly (before the countdown ends and windows restarts automatically) it will let you delay the restart for up to 4 hour. Knowing a restart will take some time which you don’t have right now, you choose to delay the restart for 4 hours… Four hours later you are off to lunch you miss the ‘restart warning’ so MS Window and all its’ brilliance goes ahead the restarts the computer. You come back from lunch and, low and behold, all your programs that you left open have been closed. Hope you saved your work before you left!
Yes, MS has similar feature.
