How to run IE 7 and IE 6 side by side
Now that Microsoft has released Internet Explorer 7 and the whole web development world is trying to figure out what works in it, and, more importantly, what doesn’t (let’s just not go there right now, ok?), I thought I’d give you some solace to your doubts whether to install it or not on your main Windows machine (most likely you have doubts what will happen to IE 6, which you, unfortunately, still need to test in and cater to, for a long time to come).
Luckily, Position Is Everything’s great article Taming Your Multiple IE Standalones still applies and is updated to be written out of the perspective of a machine with the scenario where IE 7 is the main installed web browser. It offers support for directly seeing in the title bar of each web browser which version it is, and the absolutely necessary support for conditional comments as well. Don’t fret, it takes like five minutes to set it up!
I’ve used this approach myself for a long time and for me it has worked flawlessly. I also haven’t heard any complaints from any other web developer I know. So, as usual, I’m your guinea pig for things before I write about them. 
IE 7 will automatically be download to your Windows machine
As the IE team stated, IE 7 will be automatically distributed through Windows Updates as a high-priority update. There is also a Blocker toolkit that goes with it to make you prevent this from happening. While I like the idea of cleansing every PC out there from the terrible IE 6 (but not necessarily replacing it with IE 7 ;-)), I’m not sure I like this from a web developer perspective. We like controls of our computers, and the more things that are forced upon us for our own good, the more displeased we’ll get…
If you have any experience of the multiple IE standalones, or an opinion you’d like to express about the automatic install of IE 7, don’t be shy; let me hear it!
but I guess thats my fault.
