There are plenty of generic names in software that refer to some element of the product.
Apple has a word processor called Pages, while Microsoft has one called Word. There were many applications before these that operated on pages and words.
If the trademark is “Microsoft Windows”, it’s just as specific as “Apple Pages”.
Microsoft’s own list (https://query.prod.cms.rt.microsoft.com/cms/api/am/binary/RW... - PDF warning) - while it explicitly says it is non-exhaustive - doesn’t appear to claim ‘Word’ or any variant of it - only the word icons and logos. From your list it lists Microsoft 365 and Microsoft Teams and Office 365, but not Microsoft Office.
