If you mean that you have formatted the hard-drive... you cannot 'undo' it. Wiping the hard-drive erases the reference track from the drive. The reference track holds details of all the programs, pictures and personal data - to allow Windows to find each file as required.
You can't undo it, so you should be really careful not to play with it.

There are tiny screws on the back you have to undo.

Memory is used for the purpose of running programs, for example, your text editor. The text editor stores the file you are editing as what is known as a 'buffer' in your memory instead of modifying the file in-place. This is what makes undo/redo possible.
you can not because the undone is already undone...............
If its RAM Memory then yes, but if its Hardrive Memory, then it depends, PC Restore doesn't delete most of your files, so you won't get that memory back, although, if its a program installed, then it'll undo that installation and you will get that memory back. RAM Memory restores everytime you turn on your computer and is used by however many programs you are running.

Ram is Random Access Memory. Your computer uses this memory to store temporary files (like your undo history and your unsaved changes.)
