Use the Microsoft Office Uninstall Support Tool
The most effective way to clear stubborn registry entries and leftover installation files is by using Microsoft's dedicated automated uninstaller.
Standard uninstallation through the Control Panel often leaves behind residual registry keys and licensing tokens. Using the official automated support tool ensures a completely clean slate before you install your new subscription.
Download and launch the official Microsoft Office uninstall support tool from the Microsoft support website.
Follow the on-screen prompts in the tool to detect your Office installations and authorize the removal of all leftover Office 2016 installation files and registry information.
Once the tool finishes processing, reboot your PC to ensure all old registry entries are successfully cleared from the system memory.
Navigate to the Microsoft account services page, log in with the account associated with your active subscription, and reinstall Microsoft 365.

Frequently Asked Questions
Why does Office 2016 still show up after I uninstalled it from Control Panel?
The standard Control Panel uninstaller often leaves behind registry keys and local licensing information. These stubborn remnants cause the older version's details to still appear on your Office Account page.
Will using the uninstall support tool delete my personal documents?
No, the Microsoft Office uninstall support tool only targets application files, product keys, and registry entries. Your personal Word, Excel, and PowerPoint files will remain completely safe on your hard drive.
Do I need to reinstall Microsoft 365 after using the cleanup tool?
Yes. Because the support tool completely wipes all Office-related files and configurations from your system, you must log back into your Microsoft account and perform a fresh installation of Microsoft 365.
