After its official release Windows 10 Anniversary Update, when thousands of people started installing the new operating system, some posts appeared on the company's forum reporting installation failures for unknown reasons. The error codes reported so far are 0x80070057 and 0xa0000400.
Let's say that the anniversary update is also available through Windows Update, and this is the main method that users use to upgrade their system, mainly because it is done automatically and does not necessarily require user intervention.
So if you see any of the above errors, the only way (for now) to successfully install the new Windows 10 Update is to use the Media Creation Tool which will help you create an installation tool.
Well, you understand, in order to avoid the above errors, the new operating system must start from scratch.
The Media Creation Tool will guide you through the entire installation process, and will display detailed information before each step.
Keep in mind that there is also a choice of keeping your apps and files in case you do not want to lose your old installation.
