Installing IE7b3 without WGA activation?

Hey all, first time I've been to these boards. My query may not have been entertaining enough for /g/, according to the rules, so I came here :|

I want to experience this new Microsoft-invented phenomenon of tabs and RSS, yet my copy of Windows (er, strangely) isn't valid for some reason. Or we could say I'm one of those Slashbots who thinks it's a violation of my rights to submit my OS to testing.

So basically - IE7 requires two sets of Windows validation. I solved the download validation issue - you can get Bxeta 3 here: http//download.microsoft.com/... but when you run the installer it also wants to run WGA checking stuff. How do I bypass this?

Just in advance - that weird javascript hack for "WGA" simply bypasses the check on Windowsupdate and isn't relevant to attempts to install either IE7 or WMP11 betas. Also, yeah whatever GetFirefox.com blah blah, I actually want it to test out website designs on a Mac which I primarily run Opera on.

Help would be appreciated! I haven't seen any repackged installers, WGA cracks or methods to skip the activation part of the installer anywhere yet.
