Ubuntu Fiesty - Doesn't want to be boxed!!!

Hmmn. It is over 24 days now that I had to give up the idea of running boxed WinXP from Ubuntu Fiesty. Not that WinXP was not willing to stay boxed inside Ubuntu, it actually co-operated well and was doing fine. However, there are lots of official tasks that are tied to Microsoft Products and getting them off is an Herculean task. But that is not to say that I've given up on the idea of switching over to Ubuntu.
I love the look and feel of Ubuntu. And I was reliably informed that Linux is more secure (afterall, less hackers attack it).
