Curious Wubi Question

[Arken]

If I use Wubi on my laptop here, (with 7.04) what could possibly happen when upgrading to 7.10?

I've tried it. It pretty much breaks your operating system.

Don't even think about it since you may have valuable data on your system .
But if , in case you are veeeeery curious , you want an update , you'd better back-up your /home file (on Windows) , your /opt in case there are any programs installed in there and note down your most precious programs installed as well as the patches - hacks you may have done http://www.adslgr.com/forum/images/smilies/thumbsup1.gif
