- Product
- Microsoft Word
- Device & OS
- Windows
- Scenario
- Pasting images from external graphic applications or formatting text within a document.
- Observed behavior
- The application becomes extremely slow and unresponsive, even when running on a computer equipped with modern hardware and a solid-state drive (SSD).
Save your open documents and ensure your Windows operating system and graphics drivers are fully updated, as outdated display drivers can cause rendering lags when pasting high-resolution graphics.
Open Word in Safe Mode to Disable Add-ins
Running Word in Safe Mode temporarily disables third-party add-ins and templates that might be conflicting with the clipboard or rendering engine, causing the performance issues.
Many performance issues in Microsoft Word are caused by outdated or conflicting third-party add-ins trying to process clipboard data simultaneously.
Press the Windows key + R on your keyboard to open the Windows Run dialog box.
Type winword /safe into the text box and press Enter to launch Microsoft Word in Safe Mode.
Try pasting an image from Photoshop or formatting text to see if the lag persists.
If the issue is resolved in Safe Mode, go to File > Options > Add-ins to manually disable your COM add-ins one by one to find the culprit.

Run the Microsoft Office Repair Tool
The built-in Office repair tool can fix corrupted application files or missing registry keys that cause Word to freeze during rendering tasks.
Test with a New Windows User Profile
A corrupted Windows user profile can cause application-specific slowdowns. Testing on a new profile helps isolate system-level configuration issues.

Frequently Asked Questions
Why does Microsoft Word lag specifically when I paste images from Photoshop?
Pasting images directly from heavy editors like Photoshop transfers complex clipboard data, uncompressed image formats, or OLE objects, which strains Word's rendering engine. Saving the image as a JPEG or PNG to your desktop first and using the 'Insert > Pictures' feature often resolves the lag.
Does hardware acceleration affect Word's performance when formatting?
Yes, hardware graphics acceleration can sometimes cause rendering conflicts or sluggishness on certain PCs, especially if graphics drivers are outdated. You can disable it in older versions of Word by going to File > Options > Advanced, scrolling to the Display section, and checking 'Disable hardware graphics acceleration'.
How do I stop Word from freezing when dealing with large documents?
Large documents with high-resolution images, complex formatting, and active add-ins require significant memory. Compressing pictures via 'Picture Format > Compress Pictures' and turning off background repagination can significantly improve performance.
Will repairing Microsoft Office delete my personal documents?
No, running both the Quick Repair and Online Repair tools only replaces or fixes the core software application files. Your personal documents, templates, macros, and customized settings are generally kept safe on your hard drive.
