If you have to start/stop services at all during a typically development day then this free tool will probably be a great help to you.
NOTE this is an old post and that link no longer works.
It lets you create simple profiles that start or stop various services. So if your running CF 6 and CF 7 on the same box you can jump between the two profiles very easily. Check it out!
In the future they are talking about letting you potentially queue the order of the start/stop requests which would be really handy!
I found a similar service manager:
It is free and you can request custom functions that the developer implements for you.
