How to - "Undo" Mistakes in Windows

Undo mistakes in the majority of Windows programs by pressing the shortcut key CTRL + Z. For example, if you mistakenly cut or deleted text in Microsoft Word pressing the CTRL and the Z key at the same time would undo that change.

Multiple undo

Most Windows programs also support the ability to undo multiple changes. Continuing to press CTRL + Z will undo one change at a time often back up to 12 or more changes.

Redo the undo

If you undo something you did not mean to undo pressing CTRL + Y will redo the undo.
