Contrary to Google, Microsoft often provide a migration path to another of their service covering the same usecases.

Examples:

Skype For Business => Teams.

Microsoft Edge => Chromium Edge.

Windows 10 IoT Core => It's not dead ???

Office Viewer => Web Based Office

Kinect => It's not dead ???

Microsoft Anti-Virus for Windows => Windows Defender

Come on, microsoft has big flaws but backward compat/keeping old product alive is where they are one of the best in the industry.
