nope, not making it up
I got Windows XP when it was released in 2001. I used that for two years until Windows 2003 was released. I was previously using Windows 2000 so it made sense to switch to Win2k3. In the next 4 years I continued to use Windows 2003 and intermittently dual booted into XP .
I work with everything from Flash development to C++ coding. I used to run IIS but switched over to WAMP.
After a few months, the OS would start showing anomalies. For example, right-clicking on a taskbar item would bring up the menu that would not go away. Or left clicking on the desktop would show the right-click menu instead. Sometimes the task manager would have various problems. Etc...
My usage hasn't changed so I can't attribute it to any particular action. I continue to use the same software in both OSes and I never install anything that I don't need. Some people use StyleXP or WindowBlinds but IMO it's all useless garbage, efficiency over aesthetics.
In any case, just use what works for you and unless one of us works for Microsoft, let's make money instead of convincing each other which OS is more stable
