TrustedReviews has a guide on installing Windows Vista on the MSI Wind notebook:
We've become nigh-on oversaturated with netbooks in the TrustedReviews office recently. No matter which way I turn at the moment it seems I'm confronted with an Eee PC of some variety, an Acer Aspire One or an MSI Wind. Obviously I'm not complaining about this situation - we all love netbooks, you can't not - but it does make it much harder for me to resist the temptation to do something heathen with them - like install Windows Vista.
While many of my colleagues can't seem to fathom why anyone would want to do this, I decided that consequences be damned, I was going to do it anyway. And because I think, contrary to popular opinion here, that I'm not the only one wanting to persuade Vista to run on a netbook, I'm going to tell you all how to do it, and whether it's worth the effort.
