Good idea.

I recommend that you read in Emacs Manual following section:

(info "(emacs) Saving Emacs Sessions")

You may simply evaluate the above line in Emacs to get quicker to it.

> How to do that?

There are several ways, and by using the built-in option, you simply
do:

M-x desktop-save 

to save buffers, and window configuration, and:

M-x desktop-read

to read the configuration back into Emacs.

Please read in the Info Manual how to enable the option upon startup.

I think it is only:

C-x r w REGISTER -- to insert window configuration into register.

there is no "r" after "r w" that I know.

And to restore it, it is:

C-x r j

Registers are not automatically saved when you exit Emacs. That means the state of window configuration will be deleted from memory when Emacs exits.

Package that could help with persistent state over sessions may be also following:
