Not compatible or not working well with windows 7?

Maybe, It doesn't work because the driver/application you installed is for other versions of operating system. I am also using windows 7 like you so don't you worry, You can still use your old installer/driver from other versions of operating systems. Just remember that before installing any program in a windows 7 Operating System Computer, Use "troubleshoot compatibility". Right Click the Icon of your program installer/application first, then choose "troubleshoot compatibility". This will allow you to choose on what type operating system your program will run. Just reply back if it still doesn't work.:D rate and vote for me:))
