Fix Microsoft Office Build 17231.20218 Missing Aptos Fonts and Themes
Question details
Users report that Aptos fonts and new Office themes have completely disappeared after their Microsoft Office updated to build 17231.20218.
- Product
- Microsoft Office
- Device & OS
- not provided
- Scenario
- Opening documents or attempting to format text immediately after a recent Microsoft Office automatic update.
- Observed behavior
- The default Aptos fonts and new themes are missing from the formatting options, and the installed build version (17231.20218) does not exist in Microsoft's official Current Channel release history.
Verify your current Microsoft Office build number by opening any Office application, clicking on 'File', and selecting 'Account' to see if you are running the affected build 17231.20218.
Roll Back to a Previous Stable Office Build
Since build 17231.20218 appears to be an undocumented or withdrawn update, reverting to the last known stable version (such as 17231.20194) will restore your missing fonts and themes.
Microsoft occasionally releases builds that are later withdrawn due to bugs or unintended feature removals. Rolling back your Office installation forces the software to downgrade to an official, stable release from the Current Channel.
Open Microsoft Word or Excel, go to 'File' > 'Account', click on 'Update Options', and select 'Disable Updates' so Office doesn't immediately reinstall the bugged build.
Click the Windows Start menu, type 'cmd', right-click on 'Command Prompt', and choose 'Run as administrator'.
Navigate to the ClickToRun directory by typing 'cd %programfiles%\Common Files\Microsoft Shared\ClickToRun' and pressing Enter. Then, run the command 'officec2rclient.exe /update user updatetoversion=16.0.17231.20194' to initiate the rollback.
Run the Office Online Repair Tool
If you prefer not to use the Command Prompt, running a complete Online Repair can fix corrupted update files and force Office to resync its feature set.

Frequently Asked Questions
Why did the Aptos font disappear after my Office update?
Build 17231.20218 may have been an experimental or accidental release that Microsoft quickly withdrew. When this happens, cloud-synced features like the new Aptos font family and updated themes often fail to load or are temporarily disabled.
How can I check if I am on the bugged Office build?
Open any Office application such as Word or Excel, click on 'File' in the top-left corner, and select 'Account'. Look under the 'About' section to see your current version and build number.
Can I manually download and install the Aptos font?
Aptos is a proprietary cloud font managed internally by Microsoft Office. While you can install standard fonts in Windows, the most reliable way to restore native Aptos integration in Office is to revert to a stable, officially supported build.
