关于Windows PC上是否有技术理由保留Office 365的问询

Hey Rohit, great question—let's break this down clearly based on your concerns about cloud data and your preference for sticking with Office 2016.

First off, let's cut to the chase: there's no mandatory technical reason you have to keep Office 365 installed if your core goal is keeping your work off the cloud. Here's a breakdown of the key points:

• Office 2016 is a perpetual license product built to run entirely locally on your PC. It doesn't rely on cloud connectivity to handle core tasks like creating, editing, or saving documents, spreadsheets, or presentations. As long as you restored your Office 2016 installation properly after uninstalling 365, you won't run into technical issues with basic functionality.
• The "technical advantages" of Office 365 are almost all tied to cloud integration: real-time co-authoring with teammates, automatic OneDrive backups, cross-device setting/file sync, monthly feature updates, and AI tools like Copilot. But since you explicitly don't want the cloud holding copies of your work, these features aren't benefits for you—they're exactly what you're trying to avoid.
• Uninstalling Office 365 won't break your Office 2016 setup, as long as you follow standard steps (either via Control Panel or using Microsoft's official uninstall tool with commands like Setup.exe /uninstall Office365ProPlusRetail). The two versions can coexist, but removing 365 is totally safe if you don't need it.
• It's worth mentioning that while Microsoft ended mainstream support for Office 2016 in October 2023, extended support runs until October 2025. That means you'll still get critical security updates during that period, so your Office 2016 installation will remain technically stable and secure.

At the end of the day, your choice to uninstall Office 365 aligns perfectly with your privacy priorities. There's no technical obligation to keep it around if you're happy with Office 2016's local-only functionality.
