How to lose your work using Undo Copy in Windows

[aum]

This is a simple guide on how to lose your work using the brilliant design of the Windows interface. Here are the steps:

 

1. Copy-paste a file from one folder to another. Simple.
2. Start working on the copy. Make sure to spend several hours editing the file, so your loss has some actual value.
3. Right click anywhere in Windows Explorer and press Undo Copy. You can't miss it, it's right above the "New" option:

 

 

Done. Your work is gone. Instead of panicking and trying to find ways to recover it, you should take a deep breath and make peace with the fact that you've lost several hours (or more!) for nothing.

Let's see an example

Your boss asks you to make a PowerPoint presentation. Eager to impress, you get started right away. You don't want to start from scratch so you copy a template that your company has provided, to be used for all presentations.

 

You paste the template on the Desktop and start working right away. You spend a good amount of time creating a flawless presentation. Now, since you're an organized person, you want to move the finished product to another folder, to keep your Desktop clean.

 

You right click in Explorer with the intention of doing New → Folder. Instead, you misclick and press Undo Copy, just a few pixels away. You notice in horror that your PowerPoint file is gone. You try looking in the Recycle Bin but there's nothing there.

Is there a way to recover it? What about Redo Copy?

Redo Copy does exactly what it's supposed to do. It copies the original file to the destination. It doesn't restore the edits that you made on the copy.

 

What about data recovery software? Can any of those recover your file?

 

I tried a few basic file recovery programs but none of them could do the job. Let me know if you find any software that can get you out of this mess.

Is there a way to prevent this?

Yes. Just disable this silly feature using the Windows Registry.

 

Create a DWORD entry named MaxUndoItems with a value of 0 under:

 

HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced

Alternatively you can run this equivalent command:

reg add "HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced" /v MaxUndoItems /d 0 /t REG_DWORD /f

Log off or restart and the context menu option will be gone. The associated shortcut (Ctrl-Z) will be disabled too (note that this only applies to Explorer, Ctrl-Z will still work in other programs).
