Now before everyone rushes off to bag this bargain, I should point out that you can also buy Home Premium for £166.37! Obviously excluding VAT again, Microsoft has to make a living you know.

A quick trawl online reveals the going rate for the full version of Vista Home Premium is around £130 inc VAT – and you can buy it for less than £90 inc VAT if you’re willing to opt for the more restricted OEM version, which is tied to the motherboard you first install it on (so if you build a new PC, you’ll have to buy a new copy of Windows).

So, taking away VAT, Microsoft is charging a premium of over £50 if you buy direct from its store. It would be amazing to discover just how many sales it’s made for these two excellent picks, but sadly I don’t think I’m going to get much joy out of Microsoft on that one. My guess? A princely zero.
