I bought the PC from a local reseller and it came loaded with Windows XP even though I did not pay for an operating system as I had my own copy (not the Tablet version of course). When I first turned it on I got to the screen that required a serial and the serial I had for my copy did not work.

So I reformatted and installed my copy of XP and it worked fine but with no XP Tablet PC 2005.

Now, I presume I must get my hands on Tablet version of XP, what can I do?
