So I have finally got to switch to my new laptop (windows 7, i5 lots of RAM!) and reinstalled all my tools.
This first thing that started to really annoy me was that every time I attempted to attach to the w3wp.exe process to debug Visual Studio showed a message telling me it might be a bit dangerous to do so. Clicking OK allows you to attach and debug as usual. I had to find a way to disable that message.
Apparently you can and I have! Thanks to a great little post over at thethoughtfulcoder.com it appears this can be turned off in the registry.
This is great and saved me some keystrokes however, it is the kind of thing you should be able to disable in Visual Studio itself rather than have to dig about in the registry for.
