i’m not sure i’d go as far as to say they were non-innovators. microsoft famously employed “embrace, extend, extinguish” but it required quite a bit of “extend” to be successful. ms-dos, windows, office, exchange, sql server, etc. were all solid advancements in their time.
but they’ve certainly stagnated in my mind. i still use outlook/exchange and excel, but generally migrated away from microsoft many years ago now.
I do think their Office 365 and Azure strategies will keep them around for a long while. It's significantly better than the alternatives. All the same, most of my efforts have been towards not deploying to windows centered infrastructure, though Azure itself is decent enough.
