How Long does It Take to Update Windows 10?

Here comes the million-dollar question, although no one has been able to provide any definite answer to it. Some say it takes 10-20 minutes on a powerful modern computer.

It has been reported that the latest update of Windows 10 takes almost 4 hours to finish. In an explanation of this, Microsoft says that the Windows 10 newest version uses UUP (Unified Update Platform). UUP is designed to reduce the download size of Windows 10 updates. However, downloading updates and applying updates are two different stories.
