Solution 1Recommended

Eject the Virtual DVD Drive in File Explorer

Unmount the ISO file to remove the virtual DVD drive once the Office installation is completely finished.

When you download an offline installer (ISO file) for Microsoft Office and double-click it, Windows automatically mounts it as a virtual DVD drive. This allows the system to read the installation files as if a physical disc were inserted.

Once the software is installed, you can safely unmount this virtual drive. Doing so will simply remove the temporary installation media and will not affect your newly installed Office applications.

1
Open File Explorer

Press the Windows key + E on your keyboard or click the folder icon on your taskbar to open File Explorer.

2
Locate the Virtual Drive

Navigate to 'This PC' in the left sidebar and look for the DVD drive containing the Microsoft Office installation files.

3
Eject the Drive

Right-click the virtual DVD drive and select 'Eject' from the context menu. The virtual drive will immediately disappear from the list.

Frequently Asked Questions

Will ejecting the virtual DVD drive uninstall my Office apps?

No, ejecting the virtual drive only unmounts the installation media (the ISO file). Your installed Microsoft Office applications will remain completely intact and functional.

Why did Microsoft Office install as an ISO file?

If you downloaded an offline installer for Microsoft Office, it typically comes in the form of an ISO file. This format acts like a digital disc, requiring Windows to mount it as a virtual DVD drive to access and execute the setup files.

Can I delete the ISO file after ejecting the drive?

Yes. Once the installation is fully complete and you have ejected the virtual drive via File Explorer, you can safely delete the original ISO file from your Downloads folder to free up storage space.
