Track Changes records every edit you make, and Word shows who made each change and when

Track Changes is a feature in Microsoft Word that logs every insertion, deletion, and formatting change in a document. When you turn it on, Word marks edits with colored underlines, strikethroughs, and margin comments. Each change is tagged with the editor's name, the date, and the time. The original text stays visible — nothing is permanently deleted until someone accepts the change.

This matters for privacy because Track Changes creates a detailed record of your editing process. If you share a document with Track Changes on, the recipient sees not just your final words but every false start, every rewrite, every moment of uncertainty. If you send a document with Track Changes off but the changes are still embedded in the file, someone with the right knowledge can sometimes recover them. Understanding how to use this feature — and how to clean up after yourself — means you control what story your document tells about how you wrote it.

Key Takeaways

  • Turn on Track Changes by clicking the Review tab, then clicking Track Changes; Word will then mark every edit you make from that moment forward.
  • Track Changes embeds the editor's name, timestamp, and the exact text that changed into the document file itself, so turning it off later does not erase the history.
  • Before sharing a document, you must decide whether to accept all changes (which removes the markup but keeps the final text) or reject them (which removes the edits and restores original text).
  • Deleting the change history requires accepting or rejecting every change individually, or using the "Accept All Changes" or "Reject All Changes" buttons to process them in bulk.
  • If you want to share a document without revealing your editing process, accept or reject all changes, then save the file before sending it to others.

How to turn Track Changes on and off

Open your document in Microsoft Word. Click the Review tab at the top of the screen. In the Tracking group, you will see a button labeled Track Changes. Click it once to turn tracking on. The button will highlight or change color to show that tracking is active. From that moment forward, every edit you make — every word you add, delete, or change — will be marked and logged.

To turn tracking off, click the same button again. The button will no longer be highlighted. However, turning off Track Changes does not erase the changes you already made while it was on. Those edits remain in the document, marked and visible, until you accept or reject them. Turning the feature off straightforward means Word will stop recording new edits.

What information gets stored when you use Track Changes

When Track Changes is on, Word records four pieces of information for every edit: the text that changed, who made the change, when the change was made, and what type of change it was (insertion, deletion, or formatting). The editor's name comes from your Word user profile — usually the name you entered when you first set up Microsoft Office on that computer. The timestamp is automatic and precise to the minute.

This data lives inside the document file itself. It is not sent to Microsoft or stored in the cloud unless you save the file to OneDrive or SharePoint. If you email the document to someone else, all of this change history travels with it. The recipient can see your name, your edits, and the exact sequence in which you made them. This is why Track Changes is useful for collaborative work — but also why you need to clean it up before sharing a document with someone outside your when ready team.

How to review and accept or reject changes

After you finish editing, click the Review tab again. In the Changes group, you will see buttons for Accept and Reject. Word also shows you a list of all changes in a panel on the right side of the screen (you may need to click Reviewing Pane to open it if it is not visible). Each change appears as a separate item with the editor's name, the date, and what was changed.

You can accept or reject changes one at a time by clicking on each change and then clicking Accept or Reject. For a document with many edits, this is slow. Instead, click the small arrow next to the Accept button and select Accept All Changes. This removes all the markup and keeps the final version of the text. If you want to undo all edits and return to the original document, click the arrow next to Reject and select Reject All Changes.

Once you accept or reject a change, it is processed — the markup disappears and the change is finalized. However, the fact that a change was made may still be recoverable through file metadata or version history if the document is stored on OneDrive or SharePoint. For maximum privacy, accept all changes, save the file, and then close it before sharing.

How to check for hidden change history before sharing

Even after you accept all changes, Word may retain metadata about the document — information about who created it, when it was last edited, and sometimes fragments of deleted text. To see what hidden information your document contains, click File, then Info, then Inspect Document (in some versions this is under Check for Issues). Word will scan the file and show you what metadata is present.

The Inspector can remove document properties (like your name and company), comments, tracked changes, and versions. Click Remove All next to any category you want to clean. After you remove metadata, save the file again. This does not change the text of your document — it only removes the behind-the-scenes information that Word attaches to every file.

If you are sharing a document with someone you trust, this step may not matter. If you are sending it to someone you do not know well, or if the document contains sensitive information about your editing process, running the Inspector before you send it gives you more control over what you reveal.

Why Track Changes is on by default in some shared documents

If you open a document that someone else created and Track Changes is already on, it means the previous editor left it running. This is common in workplaces where multiple people edit the same document. It is also common in academic settings, where professors and students use Track Changes to show feedback and revisions.

If you do not want your edits to be tracked, turn Track Changes off before you start editing. If you want to see what changes the previous editor made, leave it on and review their edits before you add your own. If you want to hide the fact that you edited the document at all, turn Track Changes off, accept all existing changes, and then make your edits without tracking. The final document will show only the current state, not the history of how it got there.

The difference between Track Changes and version history

Track Changes and version history are two separate things. Track Changes is a feature you control — you turn it on, you make edits, and you accept or reject them. Version history is automatic and happens in the background when you save a document to OneDrive or SharePoint. Microsoft keeps older versions of your file for a period of time (usually 93 days for OneDrive), and you can restore an earlier version if you need to.

If you use Track Changes in a document stored on OneDrive, both systems are working at the same time. Someone with access to your OneDrive can see the current version of the document (with Track Changes markup if you have not accepted changes yet) and can also restore an older version to see what the document looked like before you edited it. If you want to prevent this, you need to accept all changes, save the file, and then manage who has access to your OneDrive folder.

Frequently Asked Questions

Can I turn off Track Changes and hide the fact that I edited something?

No. Once you turn Track Changes on and make edits, those edits are recorded in the file. Turning off Track Changes does not erase them. You must accept or reject each change to remove the markup. If you want to hide your edits, accept all changes before you share the document, then save it. The final version will show only the current text, not the editing history.

What happens if I accept changes by mistake?

If you accept a change and when ready realize it was wrong, press Ctrl+Z (or Cmd+Z on Mac) to undo the acceptance. This puts the change back into tracked status so you can reject it instead. If you have already saved the file after accepting, you cannot undo it — you would need to reopen an earlier version if one exists.

Does Track Changes work the same way in Google Docs?

No. Google Docs calls it "Suggesting mode" instead of Track Changes. The concept is similar — edits are marked and attributed to the editor — but the interface and the way changes are stored are different. Google Docs also keeps automatic version history, so you can see every change that was ever made to a document, even if Suggesting mode was off.

If I share a document with Track Changes on, can the other person turn it off and hide my edits?

They can turn off Track Changes, but they cannot hide your edits without accepting or rejecting them. The changes remain visible and marked until someone processes them. If they accept all your changes, your edits become part of the final text but the markup disappears. If they reject all your changes, your edits are undone and the document returns to its previous state.

Should I use Track Changes when I am writing alone?

Only if you want a record of your editing process. For a personal document that you will never share, Track Changes adds complexity without benefit. For a document you might share later, or for work that you want to be able to review and revise, turning it on from the start means you have a complete record of every change you made.
