It would be great if they just checked for updates on startup like almost every other program. I use powerpoint twice a year. I don't need auto update taking center focus on my screen, interrupting whatever I'm doing, every week that powerpoint gets a patch.
On Windows or macOS? You can install PowerPoint via the App Store on macOS, which is great. Only MS product I have that use the MS Updater on macOS is Edge.
Both Firefox and VSCode take about 3 seconds to install updates on my PC, so it hardly matters anyway.
