What should I do if Windows 10 TH2 is not updated?

Windows 10 TH2 update does not know if you have upgraded? From the experience point of view, this comprehensive "big pill" is still very powerful, bringing a lot of new features of the user's voice, perfecting the UI interface, The performance has also been improved in all directions, and the fluency has been significantly accelerated. However, many users report that Windows Update has not been able to brush out. Why?

The most important thing is two points:
1, Windows 10 is less than 31 days old.
This is the most The general situation. In order to facilitate the reluctance of users to roll back to Windows 7/8.1, Microsoft set a 31-day period, during which users can give up Windows 10 at any time, only after this period will push you TH2.
This is no solution, only after 31 days.
2, system update settings "deferred upgrades"
Windows Update provides a variety of update installation methods, there is a "deferred upgrade" option. If you don't like to update in the first place, for example, if you are afraid of giving an error, it will be useful, but it will also make you miss the latest push.

Other notes:
1, Windows system update and Android, iOS OTA update is similar, is a process, there is always a first come, so if the above conditions are met, then patience and so on.
2, Windows Insider internal test user If you have updated TH2 before, you don't have to worry about it, the public push and the internal test are exactly the same.
3. If you have updated the beta version of TH2 and deleted it, you will not receive the push today.
4, TH2 update package is very large, about 3GB, so please be patient, and the installation is also very time-consuming, basically half an hour to an hour, or please be patient, while ensuring that the system disk free space is not less than 5GB (Not enough to insert a USB flash drive).
5, stressed many times, Windows 7/8.1 upgraded Windows 10 is prone to various inexplicable errors when patching, mainly related to software and driver compatibility.
