4 applications Microsoft 16.0.19231.20216 - 28/10/2025 are installed on my PC : Microsoft 365 - fr-fr, Microsoft 365 Apps for enterprise fr-fr, Microsoft Project Professionnel 2019 fr-fr and Microsoft viso Professionnel 2019 fr-fr.

I do not understand the need for these 4 applications.

At the same time, the storage on my PC is full which is a problem. Is it because of the 4 applications? Which of them is it possible to desinstall to free up space on my hard drive?

Since you wrote your question in English, I will reply in English as well. Please let me know if anything is unclear or if you need further explanation.

Dear @Philippe Genet,

Thank you for reaching out to the Microsoft Q&A forum. We are happy to assist you.

The applications you listed serve different purposes:

• Microsoft 365 – fr-fr / Microsoft 365 Apps for Enterprise – fr-fr

These entries correspond to the core Microsoft Office suite (Word, Excel, PowerPoint, Outlook, and related applications).

In many cases, Windows may display multiple entries for the same Office installation due to language packs, licensing configurations, or the Click-to-Run installation method. These entries do not represent separate full installations.

For more detailed information, please refer to the following resources: Duplicate applications integrated into Windows settings | Overview of deploying languages for Microsoft 365 Apps

• Microsoft Project Professional 2019 – fr-fr

A standalone application used for project management.

• Microsoft Visio Professional 2019 – fr-fr

A standalone application used for creating diagrams and workflows.

You may uninstall Microsoft Project Professional 2019 and Microsoft Visio Professional 2019 only if you no longer use them.

Removing these applications can free approximately 3 to 4 GB of disk space, depending on your installation.

I do not recommend uninstalling Microsoft 365 / Microsoft 365 Apps for Enterprise unless you intend to completely remove Office from your device.

To determine what is consuming the most storage on your device, please follow the steps below:

  1. Press Windows + I to open Settings.
  2. Go to System > Storage.
  3. Select Show more categories to see a detailed breakdown of storage usage. Image de l’utilisateur
  4. Choose Installed apps to review applications you may no longer need and uninstall them if appropriate. Image de l’utilisateur

Additionally, you can:

  • Enable Storage Sense to automatically free up space.
  • Select Cleanup recommendations to review suggested items you can remove to reclaim storage. Image de l’utilisateur

    Hi Viego Ann, many thanks for your prompt and very usefull reply which allows me to solve my problem and to free up space on my hard drive by removing Microsoft Project Professional 2019.

    I have another query to you:

    When I try to access my mail storage I have the following message: "Obtain an application to open this link 'outlookmail' your PC has no application to open this link. Try searching for a compatible application in the Microsoft Store".

    And when I click "Access to Microsoft Store" unfortunately the answer is "No application found".

    Any (usefull) help?

    Many thanks in advance, Philippe
