So get you gear ready. Find a USB stick which is big enough. 16 GB should do. In addition a PC with at least 1 GB RAM is needed. If you want to prepare a bootable Windows 10 Consumer Preview USB stick then try Rufus. It handles EFI and GPT, is free and pretty easy to use (see picture below).
Looking forward to see a public version of Windows 10 Consumer Preview soon!
