Use the Microsoft Support and Recovery Assistant to Uninstall Microsoft 365
Using the official uninstall support tool completely wipes Microsoft 365 registry keys and files, preventing it from interfering with your standalone Office 2019 version.
Simply uninstalling Microsoft 365 from the Windows Control Panel might leave residual background services that continuously attempt to upgrade older Office versions. The official Microsoft Support and Recovery Assistant ensures a clean removal.
Navigate to the official Microsoft Support website and download the Microsoft Support and Recovery Assistant (SaRA) uninstall tool.
Double-click the downloaded 'SetupProd_OffScrub.exe' file and click 'Install' to launch the application.
In the 'Uninstall Office products' window, check the box next to 'Microsoft 365' and click 'Next' to proceed. Do not select Office 2019.
Follow the remaining prompts to completely remove the software. Once finished, restart your computer when prompted to clear all background processes.
If Microsoft 365 had already fully overwritten your software, log into your Microsoft Account dashboard, go to 'Services & subscriptions', and click 'Install' next to your Office Home and Student 2019 license.

Frequently Asked Questions
Can I have both Microsoft 365 and Office 2019 installed on the same computer?
Microsoft strongly advises against running a subscription version (Microsoft 365) and a standalone version (Office 2019) on the same computer. The installation processes use the same underlying technology (Click-to-Run), which typically causes the newer subscription version to overwrite the standalone version.
Will uninstalling Microsoft 365 delete my personal files?
No. Uninstalling Microsoft 365 applications only removes the software programs (Word, Excel, PowerPoint, etc.). Your locally saved documents, spreadsheets, and presentations will remain completely untouched on your hard drive.
How do I find my Office Home and Student 2019 download link?
You can reinstall Office Home and Student 2019 by signing into your Microsoft account at account.microsoft.com, navigating to the 'Services & subscriptions' tab, locating your Office 2019 product, and selecting 'Install'.
