Word not responding means Microsoft Word freezes and stops accepting input — the title bar shows “Not Responding,” you cannot type, save, or close the document normally, and the application must be ended through Task Manager. According to Microsoft’s official Word troubleshooting documentation, the leading causes are a corrupted Normal.dotm template, conflicting add-ins, and hardware acceleration issues on systems with outdated graphics drivers.

Word not responding: Safe Mode add-in test, Normal.dotm reset, hardware acceleration, Office Repair — prioritized fix path

What causes Word to freeze and stop responding

Corrupted Normal.dotm template — Word loads the Normal.dotm template on every startup. A corrupted macro, style, or AutoCorrect entry in this file causes Word to freeze consistently, often within seconds of opening a document.

Add-in conflict — Grammar checkers, citation managers, PDF converters, and document management plugins all integrate deeply into Word. After a Word update, incompatible add-ins can cause freezes during specific operations like saving or printing.

Hardware acceleration rendering bug — Word uses the GPU to render complex documents. Documents with many high-resolution images, complex tables, or heavy use of tracked changes can trigger a GPU rendering stall that locks the Word window.

Printer driver conflict — Word communicates with the printer driver even before you click Print, to set page margins and dimensions. A corrupted or outdated printer driver can cause Word to freeze on startup or when switching documents.

How to fix Word not responding

Work through the steps in order. Safe Mode testing (step 2) quickly identifies add-in conflicts. Resetting Normal.dotm (step 3) resolves the majority of template-related freezes.

How to verify the fix

Open the document that previously caused the freeze. Type several paragraphs, save the file, and attempt a print preview. If Word remains responsive and saves successfully, the fix worked. If a specific document still freezes Word but others open normally, the document itself may be corrupted — try File > Open > Open and Repair to recover its content.
