Are you waiting in line for Windows 10? You do not have to.
Go onto google... type in "mediacreationtool" all one word... and it will link you to microsofts tool to download Windows 10 immediately.
I did this for my laptop and my desktop, it even has the method of letting you create win10 install on a flash drive/disk.
Just figured i'd post for everyone to help you get it
EDIT: If you do this method, upgrade before a full install. After full install it will ask you for Windows 10 serial, just bypass it.. and after windows starts it will activate your free copy.
