Fix Microsoft Office 2016 Slow Typing & Performance on Windows 10
Question details
The user is experiencing extreme input lag and slow performance in Microsoft Office 2016 applications, specifically while typing or navigating between cells.

- Product
- Microsoft Office 2016
- Device & OS
- Windows 10
- Scenario
- Working on new or existing documents in Office 2016 on a newly purchased, high-specification computer.
- Observed behavior
- Office applications open normally but become exceptionally slow and unresponsive during basic interactions, taking several seconds to register clicks or keystrokes.
Ensure your Windows 10 operating system is fully updated, and temporarily pause background synchronization tools like OneDrive or active antivirus scans to rule out external software interference.
Run Office in Safe Mode and Disable Add-ins
Launch your Office applications in Safe Mode to determine if third-party add-ins are causing the extreme typing and navigation lag.
Third-party add-ins integrated into Word or Excel can consume significant processing power, leading to noticeable delays when interacting with documents. Starting in Safe Mode bypasses these add-ins.
Press Windows + R to open the Run dialog. Type 'winword /safe' (for Word) or 'excel /safe' (for Excel) and press Enter.
If the application runs smoothly without lag, go to File > Options > Add-ins.
At the bottom of the window, select 'COM Add-ins' from the Manage drop-down menu and click Go. Uncheck all listed add-ins and click OK. Restart the application normally to see if the issue is resolved.

Disable Hardware Graphics Acceleration
Turn off hardware graphics acceleration to resolve rendering delays and input lag associated with display driver conflicts.
Repair the Microsoft Office Installation
Use the built-in Windows repair tool to fix corrupted Office program files that may be severely impacting application performance.

Frequently Asked Questions
Why is Excel lagging only when I move between cells?
Cell navigation lag is frequently caused by conflicts between Office's hardware graphics acceleration and your computer's display drivers. It can also happen if heavy background synchronization processes, like OneDrive, are constantly checking file status as you edit.
Does having a new computer guarantee Microsoft Office will run fast?
Not necessarily. Extreme slowness in Office on high-end hardware (like an i7 processor with plenty of RAM) is usually caused by software conflicts, outdated drivers, corrupted registry entries, or unoptimized COM add-ins rather than hardware limitations.
Can background antivirus scans cause typing lag in Word?
Yes. If your antivirus software is actively scanning your keystrokes or the temporary cache files generated by Office 2016 in real-time, it can severely delay the text appearing on your screen. Temporarily pausing the antivirus can help diagnose this.
