How to Fix Slow Microsoft 365 Performance on Windows 10
Question details
The user needs to resolve performance issues where Microsoft 365 applications respond slowly and lag during data entry.
- Product
- Microsoft 365
- Device & OS
- Windows 10
- Scenario
- Typing text or entering numbers into Microsoft 365 applications like Word or Excel.
- Observed behavior
- The applications exhibit noticeable lag, causing typed characters or numbers to appear on the screen with a significant delay.
Ensure that your Windows 10 operating system is fully updated and temporarily close any heavy background applications to free up system resources before troubleshooting.
Start Microsoft 365 in Safe Mode
Running Office in Safe Mode bypasses add-ins and customizations, helping you identify if a third-party extension is causing the typing delay.
Safe Mode is a diagnostic tool that loads the application with basic functionality. If the lag disappears in Safe Mode, an installed add-in is likely the root cause of the slowdown.
Press the Windows key + R on your keyboard simultaneously to open the Run dialog box.
Type the command for your specific application (for example, type 'winword /safe' for Word or 'excel /safe' for Excel) and press Enter.
Begin typing text or numbers in the new document. If there is no delay, you will need to disable your COM add-ins one by one to find the problematic extension.
Run the Microsoft 365 Online Repair Tool
If Safe Mode does not resolve the issue, repairing the Office installation can fix corrupted system files causing the application to lag.
Check Account Details and Update Office
Outdated software versions can contain performance bugs. Forcing the latest Office updates may instantly resolve typing lag.

Frequently Asked Questions
Why is there a delay when I type in Microsoft Word or Excel?
Typing delays are typically caused by conflicting third-party COM add-ins, outdated display drivers, or corrupted Office installation files. Working with extremely large files containing complex formatting can also contribute to performance slowdowns.
Will completely reinstalling Microsoft 365 fix the performance issues?
Yes, if the built-in Online Repair tool fails to resolve the lag, completely uninstalling and then reinstalling Microsoft 365 can replace deeply corrupted system files or registry entries causing the slow performance.
How can I disable hardware graphics acceleration in Microsoft 365?
