Windows is no longer Microsoft's main focus, and hasn't been for quite a few years. It's about 12% of their revenue. The main income is now Azure, Office 365, and an assortment of other smaller (comparatively) things like Surface, X-box, GitHub, etc. If Windows revenue would drop off to 0 tomorrow it would be a blow, but Microsoft would survive just fine. People keep thinking about Microsoft in 2001 terms but it's not the same company. This what Satya Nadella brought to Microsoft (don't think it would have played out like this under Balmer).
