user18808: How do I use my wallet.dat on my windows 8 bitcoin qt?
Someone posted this 
C:\Documents and Settings\YourUserName\Application data\Bitcoin (XP)
C:\Users\YourUserName\Appdata\Roaming\Bitcoin (Vista and 7)
but I'm on windows 8, so i don't know what to do

user17113: Windows 8 is just like Windows 7. 
But on a mondern bitcoin-core installation you will be asked where to put your data-directory. So if you changed the default path you need to consider that.
So if you found your data directory, your wallet.dat file is right there. Make a backup or restore it as you wish.
There is also a good tutorial video around for more visual explanation.
For a more detailed explanation on what steps are required to restoring your wallet.dat you can check out this post.
