Microsoft on Monday shared details on how enterprise customers can transition to its new Windows 10 Anniversary release. By Tuesday, however, a few users were reporting issues during installation, with error codes providing no information on how to resolve the issue.

Also known as Build 14393 or 1607, the Anniversary Update was widely available as of Monday afternoon (EST) to volume licensees via  the Microsoft Volume Licensing Service Center.

Some of those new updates of note for IT departments include:

The Windows 10 Anniversary Update is being rolled out to Windows 10 PCs across the world in phases starting with the newer machines first, according to Microsoft, with Windows 10 Professional, Enterprise, and Education edition customers provided the option to defer Windows updates.

According to chatter on Microsoft’s Community forums, a minority of end users are having installation issues, receiving error codes such as  0x80070057 and 0xa0000400.

Microsoft has yet to officially acknowledge the bug issue, signalling that the occurence is most likely not a widespread issue; according to, one way to resolve the issue is to  perform a clean install to the operating system using the Media Creation Tool. The tool effectively guides users throughout the step-by-step installation process.
