Question details

- Product
- Microsoft Word
- Device & OS
- not provided
- Scenario
- Editing large, shared Word documents with a heavy volume of tracked changes and comments.
- Observed behavior
- The document becomes extremely slow, unresponsive, and lags during editing, even when revisions are set to be hidden or Microsoft Word is running in Safe Mode.
Ensure you have saved a backup copy of your document before applying any changes or accepting revisions, so you do not accidentally lose any critical editing history.
Accept or Reject Tracked Changes to Reduce File Complexity
The most effective way to eliminate the lag is to resolve and clear old tracked changes and comments, which heavily burden the document's background processing.
Tracked changes continuously consume system memory and CPU power because Word must calculate formatting and layout adjustments for every recorded keystroke. Hiding them only changes the visual display; it does not stop the background processing.
Launch Microsoft Word and open the document experiencing the severe lag.
Click on the 'Review' tab located on the top ribbon of the Word interface.
Click the 'Accept' or 'Reject' dropdown to review changes individually, or choose 'Accept All Changes' to permanently apply them and clear the tracking data.
Remove unnecessary comments by clicking the 'Delete' button in the Comments group and selecting 'Delete All Comments in Document'.
Save your document, then restart Microsoft Word to verify if the performance has improved.
Disable Unnecessary COM Add-ins
Third-party add-ins can conflict with heavily edited documents, causing additional lag.
Update Office and Test Document Integrity
Performance issues can sometimes be caused by an outdated Office version or background sync issues with other collaborators.

Frequently Asked Questions
Why does Microsoft Word lag so much when Track Changes is turned on?
Track Changes continuously records every keystroke, deletion, and formatting adjustment. In large documents, this creates a massive amount of hidden data that heavily consumes your computer's memory and CPU, leading to severe visual lag and freezing.
Does hiding the revisions improve Word's performance?
Hiding revisions by selecting 'No Markup' or 'Simple Markup' can slightly improve immediate display rendering, but the data is still being processed in the background. To truly resolve the lag, you need to systematically accept or reject the changes.
Will running Word in Safe Mode fix the lag caused by tracked changes?
Safe Mode disables add-ins and custom templates, which can help if an external add-in is conflicting with the document. However, it does not reduce the core processing load of the tracked changes themselves, so heavily marked-up documents may still lag.
How can I share a clean version of my document without losing the edit history?
Save a copy of your document using 'Save As' and give it a new name (e.g., 'Document_Clean.docx'). In this copied version, go to the Review tab, click 'Accept All Changes', and delete all comments. This gives you a fast, clean version to work with while keeping the original file as your historical record.
