Dont use the Metro interface and it practically looks and functions like most previous versions of windows.
If you want to use Metro then just turn it back on.
The Metro interface can be used with a mouse as well as with touch screens
And if you want to really customise it to suit then go here

you can also get free apps that will do the same as most of the Stardock ones
For £25 its crazy not to get it, put it on a seperate partition and dual boot and then you can learn to use it in your own time.
INMO best version of Windows yet by a long stretch for home users
