C-x r w r

Save the state of the selected frame's windows in register r (window-configuration-to-register).

C-x r f r

Save the state of all frames, including all their windows (a.k.a. frameset), in register r (frameset-to-register).

Use C-x r j /r/ to restore a window or frame configuration. This is the same command used to restore a cursor position. When you restore a frame configuration, any existing frames not included in the configuration become invisible. If you wish to delete these frames instead, use C-u C-x r j /r/.
