Phil,
I bought 8.0 to stick on an existing laptop - not touch screen - that was running Vista, only because it was on offer and half the price of Win 7. Big mistake. So I replaced the interface with the freebie non-touch screen version, which was fine except if you go into a folder of pictures and click on a picture, it displays OK on Irfanview, my default viewer because I hate Windows Media Player. Then click on Next to get the next picture and the damned operating system reverts to the touch screen version and Windows Media Player. You can't update to 8.1 without splashing out a load of money and I don't use the laptop very often. Just one of 8.0's annoying features!.
