You may want to take a seat, this may be a bit of a shock to you; this is a website about technology. Perhaps surprisingly, the desktop many of us have to support counts as "technology". Therefore, the company behind the OS on these desktops gets attention. More so when they make as many boneheaded moves as MS has over the past several years.
For a while there, MS was doing "OK". Windows 7 was decent ( even though they moved shit around on me and broke some functionality that was useful to admins in xp...but I digress ), security was 1000% better than it used to be. They were really picking up steam, especially after vista.
