I know most of the general public doesn't come here, but I will post the advice I give to them anyway. If you buy a new PC that has Windows 8, and you are lost, or just plain don't like it, return it. Even if it was a gift, what use is something that won't do what you need or is a pain to use? It doesn't make you a bad person to return it. You may have downgrade rights to Windows 7 Professional if it came with 8 Pro, but you need a Windows 7 install disc just to use them. If you try to do it anyway when your system is not covered by downgrade rights, expect no support from the manufacturer so you may have trouble finding all the device drivers.
There are off-lease refurbished computers that have Windows 7, or maybe Vista, or even XP that are a better buy. Dell even has an Ebay store to sell them. Nearly all of these are business computers which are of higher quality than home computers, as big business has the power to punish vendors who push manufactured garbage, unlike individual consumers.
If a few individuals send Microsoft nastygrams about Windows 8, it will not matter. "We got your money, sucker!" is their attitude, but if manufacturers complain that all their Windows 8 PCs are being returned, Microsoft will have to respond eventually.
Hate Windows 8? You don't have to take it, you can take it back.
