🖥️ PC App Microsoft 365 Minimal Online Installer | Word + Excel + PowerPoint Only | Auto ODT Download

[cartiergomora00]

I made a simple Microsoft 365 Minimal Installer using a Windows batch file.

The purpose is simple: install only the Microsoft 365 apps I actually need without manually downloading the Office Deployment Tool or creating configuration.xml.

Apps Included​

Microsoft Word
Microsoft Excel
Microsoft PowerPoint

Apps Excluded​

Access
OneNote
Outlook
New Outlook
Publisher
Teams
Skype for Business / Lync
Groove
OneDrive from the Office deployment

The script does not forcibly uninstall separately installed Microsoft Store apps or unrelated Microsoft software.

Features​

The BAT automatically handles most of the setup:

• Automatically downloads Microsoft's official Office Deployment Tool
• Tries to retrieve the current ODT directly from Microsoft
• Downloads Office files directly from Microsoft servers
• Verifies the Microsoft digital signature of the downloaded ODT
• Verifies the extracted setup.exe
• Detects an existing Microsoft 365 Click-to-Run installation
• Reuses a supported existing Microsoft 365 product configuration when possible
• Automatically generates the required configuration.xml
• Keeps the existing Office architecture/update behavior when applicable
• Uses your Windows language when doing a clean installation
• Does not use RemoveMSI
• Does not automatically remove unrelated MSI programs/components
• Does not force-close Office applications
• Verifies Word, Excel and PowerPoint after installation
• Has a safe test mode before actually installing anything

Supported Microsoft 365 Editions​

For a clean installation, you can select from:
Microsoft 365 Personal / Family
Microsoft 365 Business Standard / Premium
Microsoft 365 Apps for business / no-Teams
Microsoft 365 / Office 365 Enterprise
Microsoft 365 Apps for enterprise / no-Teams
If the BAT detects an already supported Microsoft 365 installation, it will try to use the detected product instead.

How to Use​

1. Download Install-Minimal-Office365-FINAL.bat
2. Right-click it
3. Choose Run as administrator
4. Follow the prompts

You can place the BAT anywhere, including your Desktop.

Test Mode​

Before installing, you can test it first with cmd:

Install-Minimal-Office365-FINAL.bat --test
This checks the system, downloads/verifies ODT, generates the XML, and stops before installing Office.

Result​

The installer keeps only:
Word
Excel
PowerPoint
and excludes the other Microsoft 365 apps configured in the script.

Updates​

The script does not lock Office to an old build. It downloads the applicable Microsoft 365 version directly from Microsoft.

Existing Office​

If the script detects an unusual or unsupported Office installation, it stops instead of modifying it automatically.
It also does not remove unrelated MSI-installed programs.

Activation​

This script only handles installation/configuration.

A valid Microsoft 365 license or subscription is still required.

Requirements​

Windows 10 / Windows 11
PowerShell 5.1+
Internet connection
Administrator access
Valid Microsoft 365 license
