This always happens with new Windows builds. In the Windows 10 Pro Group Policy Editor you can set Windows to only upgrade to feature updates when there enter a final release build thats been thoroughly tested.
Enable this policy to specify the level of Preview Build or Feature Updates to receive, and when.
* Preview Build - Fast: Devices set to this level will be the first to receive new builds of Windows with features not yet available to the general public. Select Fast to participate in identifying and reporting issues to Microsoft, and provide suggestions on new functionality.
* Preview Build - Slow: Devices set to this level receive new builds of Windows before they are available to the general public, but at a slower cadence than those set to Fast, and with changes and fixes identified in earlier builds.
* Release Preview: Receive builds of Windows just before Microsoft releases them to the general public.
* Semi-Annual Channel (Targeted): Receive feature updates when they are released to the general public.
* Semi-Annual Channel: Feature updates will arrive when they are declared Semi-Annual Channel. This usually occurs about 4 months after Semi-Annual Channel (Targeted), indicating that Microsoft, Independent Software Vendors (ISVs), partners and customer believe that the release is ready for broad deployment.
