[clue] [Windows] Upgrading OS

[grant at amadensor.com]

I am working on upgrading my Debian 6.0 machine to Windows 7.  I am  
looking for the increased reliability, lower overall cost, and the  
ability to run the only real browser, Internet Explorer, without  
jumping through so many hoops.

Does anyone have any ideas for doing an in place upgrade, so I don't  
have to back up all of my data to an external drive?   It is over a  
terabyte, and will take a long time to copy off and back.  I would  
like to at least keep my home partition.

Ideally, I would be able to use it as is from Windows 7.   I would  
also like to transfer over all of my applications too, but expect that  
I will need to reinstall most of them from scratch.  Has anyone gotten  
K3B working in Win 7?
