Xbox 360 Controller Bug in Build 7068?

I have used my Xbox 360 wired controller with my PC for a while, on both XP and Vista prior to installing Windows 7 Betas. The first time I noticed this was with build 7068 x64, which is what I am currently using. If anybody else has a wired xbox 360, let me know if you can reproduce this.

If I have the controller plugged in, or plug in the controller while the computer is on and in windows, if I unplug it or detach the cable at the auto-release point, the computer locks and automatically reboots.

I have reproduced this a couple of times, using different USB ports on my computer and using other USB devices and haven't found that anything else reproduces the same event.

duplicated the same issue. get an IRQL NOT LESS OR EQUAL type BSOD.

Yeh, from what I've heard. They say it's fixed in 7100.

I have bought the XBox 360 Wireless Controller (Black) with the Play and Charge Kit. I plugged it into my Windows 7 Ultimate Edition x64 and the drivers did load automatically. So now that has happened what is next? I see it in the Device Manager and Devices and Printers Control Panel. The Games for Windows game that I'm trying to use it with is not seeing it and the controller is just blinking at me instead of locking into controller 1.

Did I miss something?

Thanks,
Ben
