Word crashes closing docs with tracked changes – fix

Quick answer for advanced users

Open Word in safe mode (hold Ctrl while launching), disable all COM add-ins, then remove the ~$*.docx temp files from %temp% and %appdata%\Microsoft\Word. If the doc still crashes, use the Open and Repair tool.

Why this happens

Tracked changes are stored in the document's XML under revision marks. When a doc has dozens or hundreds of tracked changes (especially with comments and formatting changes), the XML can get bloated or corrupted. Word tries to flush these changes to disk on close, and if the temp swap file – the hidden ~$ file – gets out of sync, Word crashes instead of saving. You'll see "Microsoft Word has stopped working" or the window just vanishes. This happens most often on files opened from network shares or OneDrive, because sync conflicts corrupt the revision history.

Fix steps – the order matters

1. Close Word completely. Check Task Manager for any WINWORD.EXE processes still running. Kill them if you see them.
2. Clear the temp files. Press Win + R, type %temp% and hit Enter. Delete everything in that folder (skip files in use). Then go to %appdata%\Microsoft\Word and delete all files starting with ~$. These are leftover swap files from crashed sessions.
3. Open Word in safe mode. Hold down the Ctrl key and click the Word icon. Keep holding Ctrl until Word asks if you want to start in safe mode. Click Yes. If Word starts without crashing, you've got an add-in problem.
4. Disable all add-ins. In safe mode, go to File > Options > Add-ins. At the bottom, set "Manage" to COM Add-ins and click Go. Uncheck everything. Click OK. Restart Word normally. If it now opens without crashing, re-enable add-ins one by one to find the culprit. The usual suspects are PDF creators, grammar checkers like Grammarly, and old Citrix receivers.
5. Open the problematic doc using Open and Repair. Start Word normally (or safe mode), go to File > Open. Browse to the document. Click once on the filename, then click the dropdown arrow next to the Open button. Choose Open and Repair. Word will try to rebuild the document's internal structure, stripping minor corruption. After it opens, immediately accept or reject all tracked changes: go to Review tab > Accept dropdown > Accept All Changes, then Reject All Changes if you want clean. Save under a new name.
6. Copy content into a fresh document. If Open and Repair still causes a crash on save, open the repaired doc, press Ctrl+A to select everything, then Ctrl+C. Close the doc (carefully), create a new blank doc, and paste special as unformatted text (Ctrl+Alt+V, select Unformatted Text). Reapply formatting manually. This strips all hidden revision data.

What if the main fix doesn't work

Two backup options:

• Repair Office installation. Open Control Panel > Programs > Programs and Features. Find Microsoft Office in the list, right-click, choose Change. Select Quick Repair first. That takes about 5 minutes. If Word still crashes, run Online Repair – it'll download fresh install files, so you need a stable internet connection.
• Disable hardware graphics acceleration. In Word, go to File > Options > Advanced. Scroll down to Display and check Disable hardware graphics acceleration. Click OK. This stops Word from using your GPU for rendering, which sometimes triggers crashes with tracked changes on certain graphics drivers (especially Intel HD Graphics 620 on older laptops).
• Check the Normal.dotm template. Close Word. Press Win + R, type %appdata%\Microsoft\Templates. Rename Normal.dotm to Normal.old. Restart Word. A fresh default template gets created. This wipes any corrupted toolbar or macro settings that might interfere with tracked changes saving.

Prevention tip – keep this habit

Before you close any document that has tracked changes, always accept or reject all changes first. I know it's tempting to leave them for later, but a doc with 200+ tracked changes that you edit across multiple sessions is a crash waiting to happen. If you absolutely must keep the history, use the Review tab's Compare Documents feature instead: save a clean copy, then compare the original with the clean version. That creates a separate comparison report that doesn't corrupt the working doc.

Also, set Word to autosave every 1 minute (File > Options > Save > Save AutoRecover information every 1 minute). If Word crashes, the recovered file usually opens clean because AutoRecover snapshots don't carry the corrupted tracked-change data.
