Should You Uninstall Microsoft 365 (Office) or the en-US Language Pack?
Question details
Determine whether to remove Microsoft 365 (Office) or the Microsoft 365 - en-us application from Windows Settings without breaking the main installation.
- Product
- Microsoft 365
- Device & OS
- Windows
- Scenario
- Cleaning up the Windows installed apps list to remove duplicate or unnecessary Microsoft 365 application entries.
- Observed behavior
- Both 'Microsoft 365 (Office)' and 'Microsoft 365 - en-us' appear in the Windows Apps list, causing confusion over whether two complete installations exist and which one is safe to remove.
Before uninstalling any application, verify which entry represents your active Microsoft 365 installation by checking the file size and installation date to avoid removing critical software components.
Identify and Safely Remove Unnecessary Office Installations
Carefully check your installed apps list to ensure you only remove a true duplicate installation or the web portal app, rather than a required language pack.
Seeing both 'Microsoft 365 (Office)' and 'Microsoft 365 - en-us' does not inherently mean you have two full desktop versions installed. The 'en-us' version is typically the language pack providing English spelling, grammar, and interface text. Removing the wrong entry can severely affect your main Office suite.
Press the Windows key + I on your keyboard to open Settings, then navigate to Apps and select Installed apps (or Apps & features).
Scroll down or use the search bar to look for 'Microsoft 365'. You will likely see multiple entries such as 'Microsoft 365 Apps for enterprise/personal', 'Microsoft 365 (Office)', and 'Microsoft 365 - en-us'.
Look closely at the file sizes. The main installation will be large (often over 1GB). The 'Microsoft 365 - en-us' entry is your language pack. The 'Microsoft 365 (Office)' entry is often just a small Progressive Web App (PWA) portal that links to the online versions of Word and Excel.
If you only use the desktop apps and wish to remove the web portal, click the three dots next to 'Microsoft 365 (Office)' and select Uninstall. If you see two massive desktop installations (e.g., both Personal and Enterprise), uninstall the one you no longer have a license for.
Once the uninstallation is complete, restart your computer. Open Excel or Word to verify that the desktop application still opens and functions correctly.

Frequently Asked Questions
What happens if I accidentally uninstall the Microsoft 365 en-US entry?
Removing the en-US language pack strips the English interface and proofing tools (like spell check and grammar suggestions) from your Office applications. You will need to redownload and reinstall the language pack from your Microsoft account to restore these features.
Can having multiple Microsoft 365 installations cause issues?
Yes. If you have multiple full versions of Microsoft 365 installed simultaneously, it can lead to update failures, add-in compatibility problems, broken file shortcuts, and decreased overall system performance.
Is 'Microsoft 365 (Office)' the same as my desktop Word and Excel?
No. The entry explicitly named 'Microsoft 365 (Office)' is typically a free web portal app pre-installed on Windows. It serves as a dashboard to access online, browser-based versions of Office, whereas your full offline apps are usually listed under names like 'Microsoft 365 Apps'.
