2
Navigate to the Account menu

Click on 'File' in the top-left menu, then select 'Account' from the left-hand sidebar.

3
Access Update Options

Under the 'Office Updates' section, click the 'Update Options' drop-down button to expand the menu.

4
Disable updates

Select 'Disable Updates' from the list. If prompted by the Windows User Account Control (UAC), click 'Yes' to confirm the change.

Frequently Asked Questions

Can I disable only the Fluent Design update without stopping security updates?

Currently, Microsoft bundles UI updates like Fluent Design with general security and feature updates. You cannot isolate and block only the interface changes through standard Office settings.

Why does my Office update option turn itself back on?

Sometimes Windows Update or background Office maintenance tasks can override user settings. If disabling updates via the Account menu doesn't stay applied, check your Windows Update advanced settings or reach out to Microsoft Support.

How do I revert to the old Office interface if Fluent Design is already installed?

If the update is already applied, look for a megaphone icon (the 'Coming Soon' feature) in the top right corner of Word or Excel. Clicking it may reveal a toggle to turn off the new experience, though Microsoft often removes this option once the UI becomes permanent.
