Improvements and fixes
This update includes quality improvements. No new operating system features are being introduced in this update. Key changes include:
- Addresses an issue in Microsoft Edge with using the drag-and-drop feature to upload folders from the Windows desktop to a file hosting service website, such as Microsoft OneDrive. In some scenarios, files contained in the folders fail to upload, with possibly no error reported on the web page to the user.
- Addresses an issue that degrades Internet Explorer performance when you use roaming profiles or you don't use the Microsoft Compatibility List.
- Addresses updated time zone information for Fiji.
- Addresses time zone changes for Moroccan daylight standard time.

- Addresses an issue that causes the Brightness slider preference to be reset to 50% when the device restarts.
- Addresses an issue with the OEM manufacturing processes when running sysprep /generalize.

As a result, the affected devices will not receive conditional access compliance approval and may be blocked from access to corporate resources such as email.
- Addresses a performance issue with vSwitch on network interface cards (NIC) that do not support Large Send Offload (LSO) and Checksum Offload (CSO).
- Updates the Wi-Fi policy for service set identifier (SSID) filtering to avoid filtering out Wi-Fi Direct devices.
- Addresses an issue that causes rasman.exe to stop responding.
- Addresses an issue in which regedit.exe fails to add double null terminator to REG_MULTI_SZ values in the Windows registry. The missing terminator may prevent services and applications from reading REG_MULTI_SZ values that regedit.exe adds after installing the operating system.
- Addresses an issue with RemoteApp visibility that may cause the main window to disappear until the user clicks the screen.
- Addresses an issue that prevents some users from setting Win32 program defaults for certain app and file type combinations using the Open with… command or Settings > Apps > Default apps.
- Addresses an issue that may cause mapped drives to fail to reconnect after starting and logging onto a Windows device.
