Since Microsoft windows
system update to take direct updates instead of iso update, many netizens are curious, directly update and use iso image to install updates What is the difference between the methods, here is a brief introduction.

Microsoft has released the ISO image (download) for win10 th2, so what is the difference between checking the update directly in the system and using the ISO installation?
Microsoft said that in fact these two options are almost the same, as seen from version 1511. Although we can use the ISO file to create the installation media, we will perform the upgrade from the beginning. Windows Update also uses the same method to install updates.
Different from regular updates (“Tuesday Patch Day Update), during the Windows Update download Windows 10 November update (TH2), the $WINDOWS.~BT folder created by the C drive, the installation files Same as ISO image file.
The only difference is that the Windows update installation process is more automated, and performing a manual upgrade requires the user to make several choices. But the actual installation process is the same. However, whether using Windows Update or ISO image file upgrade, the current version of Windows 10 will be deleted, or some files or applications will be deleted.
But remember, if you force an upgrade to the November update, you will no longer be able to downgrade to Windows 7 or Windows 8.1.
An additional November update will also create a Windows.old folder to retain the previous installation files and, if necessary, use Windows 10's recovery feature to roll back. This, whether you use Windows Update or ISO image, you can see the Windows.old folder.
