Window 7 Errors in Web Development

Window 7 Operating System is still not yet ready for Web developers, when I am having my coding in XP Operating System, it all works fine, but when I continue working to my web application in Window 7 it occurs so many error message and it really consumed my time figuring out why that happen, as part of my  conclusion window 7 is  the least option when coding especially in PHP and Cold fusion programming language, I rather prefer XP for more convenient and compatibility used.
