Not so much windows, but if you run your app in ie, you will run out of memory in a day or so. I had auto reboot every night at midnight. On the other hand I have run a small tomcat server on a cheap hp box running bare minimum win7, and it literally ran for years without an issue.
At one point I was writing a small custom DS platform for a client with a big corporate MS it staff. They all had their microsoft books on their desks relating to their job responsibilities. Any mention of something that didn't have a ms or cisco logo on it, was instantly meet with disapproval. Long story kinda short, I failed and lost out to another vendor, because i couldn't convince the IT guy I had been partnered with that Java and javascript weren't the same thing. I was having issues with js on ie9, they read it as incompetence; little do they know (or not now for that matter).
