How can I uninstall windows 10 technical preview?

[LightningStriker]

So as you can see in the title I have downloaded the windows 10 technical preview and didn't really like it and I want to go back to windows 8.
I still have my windows 8 64bit CD if that will help.

Boot from your Windows 8 install DVD, select Custom, and delete all partitions.
Let Windows install to that single large partition.

(Assuming, of course, you saved anything that you need from the Windows 10 install)

If you installed window 10 TP over your previous windows:
