Issue/Question
How can I undo a change made on my computer?
Environment
Cause
If the change has just occurred, depending on what was done, you may be able to use the Undo command to revert files and settings back to the previous state. This does not always work for every situation and typically must be done immediately after the change was made.
Resolution
Windows
Press CTRL + Z simultaneously on the keyboard to process this command.
macOS
Press Command ⌘ + Z simultaneously on the keyboard to process this command.
