Anniversary Update for Windows 10 is RTM
Microsoft has it not yet officially acknowledged, but apparently the development for the Windows 10 Anniversary Update that has been announced for the 2nd of August has been finished. Build 14393 that has been available in the Fast Ring of the Windows Insider Program since the beginning of last week, is since Thursday also available in the Slow Ring. This release is called Windows 10 1607 10.0.14393.0.
According to Microsoft, all known errors concerning the desktop version have been eliminated in build 14393. However, the same build may still provoke severe problems with Windows 10 Mobile. For example, some mobile devices will have difficulties with WLAN connections or problems to disable Bluetooth which - in the worst case - will result in a complete system crash.
