I saw Microsoft released a blog writing tool as a windows live app. I decided to try it at work and at home. The installer has one step where it checks for existing windows live apps. It bothers me that Microsoft has a dozen or so apps, yet it spends a lot of time looking for them.
It takes longer for the installer to look for those 12 apps than to do the rest of the install.
I can only guess what they are looking for, but I suspect that step is just mislabeled. Sometimes its the small details that give you uneasy feelings.
