Multiple language versions of Microsoft 365 & Onenote have suddenly appeared in installed apps

I noticed today that entries for Microsoft 365 and Onenote in about one and a half dozen different languages have appeared in installed apps, all installed on 24 September. This is nothing that I installed - looking at update history for Windows Update, it appears to have been part of what is shown as Click-to-Run Update Support, which is the only update installed on that date, and that wasn't an update that I selected to install.

As I have neither MS Office nor Onenote installed (I've never used either), why has all this crap suddenly appeared? I used Bulk Crap Uninstaller to uninstall all 30-odd apps, though even using that was a pain in the arse, as the uninstalls can't be run silently - for each app you have to click "Uninstall" (or whatever the translation is in the particular language version), wait for the uninstall to complete, and then click "Finish" (or translation) for the next uninstall to start.

I also can't see any way to uninstall Click-to-Run Update Support. How do I do that? For the time being I've gone into services and stopped and disabled the Microsoft Office ClickToRun Service.

Probably Microsoft detected you don't have Office and this is an attempt to make you subscribe to Office 365. Ipon loading any language you will be prompted to subscribe. My wife bought a new laptop a couple of months ago and had about 10 different languages of Office 365 pre-installed. I had to remove all of them one-by-one before I could install the standalone Microsoft Office 2024. It took me more than one hour just uninstalling them! It might be faster to just format the disk and clean install Windows 11 again, but my wife would freak out.
