1 you're using the wrong icon. That's the iSteve from Apple, not Monkey-boy Ballmer.
2 it is a very, very, VERY bad idea to do an upgrade install on Windows. Doing that will work, sometimes. However, more often it will _seem_ to work, only to barf all over the place a few days later and cleaning up the mess will take longer than it would have to just do a proper install in the first place. Windows is _not_ Mac OS X or even Linux. Doing an in place upgrade with OS X works almost all the time. Doing an in place upgrade with Windows is begging for trouble.
3 even if doing an in place install would work reliably, which is not so, doing such an upgrade in any orginisation larger than a mom&pop shop is a massive waste of time. It would be far faster to identify the hardware that will be upgraded, identify the software which will be installed (including OS) and then to generate an image for each type of hardware and for each department required. Setting up each image takes time, but once the images are set they can be dumped over the network to the proper machines overnight. All drivers, applications, etc will be installed properly and will be ready to go by the time the first users show up in the morning. No muss, no fuss, no pain at all. (User data is, of course, stored on a network share and is properly backed up. Anything not in that share will be history, 'cause the first thing the imaging process does is to wipe the user hard drives clean...) There is simply no way that I'd have my boyz'n'grrlz wonder the building doing in place upgrades, not even to Macs, where at least it'll work. (_My_ Mac on _my_ desktop, both at the office and at home, gets an in place upgrade, as do some of the Chosen Few; everyone else gets an image dropped from on high, just like the WinBoxen. It's just faster and easier that way.) Nah, we image 'em. We've been imaging them for _years_. The only WinBoxen which get updated by hand are the machines we use to build new images on... and they get the nuke and pave treatment: reformat the drive, and do a clean install of the relevant software from drivers on up.
