if you do a "clean" install off of the DVD w/out formatting the drive, it just moves your old windows, documents and settings, and program files directories to windows.old and installs clean. This way you don't lose any data from XP, but don't have to worry about all the clutter of upgrading : you just grab the pieces you want and copy them over. I have done this on 4 win 7 installs, and it couldn't be easier. the Migsetup.exe wizard tool is another easy way to do this as a clean install but w/out losing data. I think the installer is top notch. My only request would be an "advanced" button to allow people to pick a little more granularity as to what packages are being installed. I have "ultimate" but I don't need/want media center, and other various pieces.

just my .02, seems like the most solid version of windows yet. Been using it since beta @ work, home, etc. and had nothing but good experiences.

This is partially true. I believe it's a joint venture w/ Fox?

It sounds like rebooting the device actually clears the worm but they have so much malware traffic in the network that it gets reinfected due to them being unable to update the software w/ the fix...

Seems like the best solution would be a handy network engineer blocking these communications at layer 4...then you reboot the devices at your leisure and eventually you should be relatively clean.

(this assumes a lot, it's hard to say what shape the environment was in)
