In this post, I will try to keep the Windows 10 version Numbers and Windows 10 build numbers. There was many issues about Windows 10 upgrades and quality of upgrades. There are less number of hotfixes released in the latest versions of Windows 10. So Windows 10 quality is getting stabilized with new versions.
