Thought the same thing. I have an additional windows machine at work now and over many years, I honestly forgot how annoying that system is in day-to-day work. Top of the annoyances:

- Unresponsive (in general... win7 on a serious "desktop replacement" class laptop with loads of resources)

- Rebooting almost every day (application updates)

- Microsoft applications constantly crashing (mostly outlook)

- Randomly failing to hibernate

- Third-party support/driver applications which I should never hear about spamming me with questions (you scheduled a backup, do you really want to make a backup now? you scheduled disk maintenance, do you really want to run it? hey, I'd like to update, can I? oh, actually there are no updates available, kthnxbye. look at me, I'm updating the virus database!)

Unfortunately these are exactly the same reasons why I stopped using windows over a decade ago...

Or stupid pieces of software installed with drivers that look like they were designed by a 12 year old (Let's make the interface surrounded by animated flames... then Evel Knievel can burst through the flames when the program loads... and then burst into flames! Yeah! Oh, yeah. We'll also throw in some hardware controls to turn on/off the bluetooth adapter that this is packaged with... ATI Catalyst, I'm looking at you...)
