Microsoft first announced the Windows 10 May 2019 Update in the beginning of April, promising to let it bake in the Release Preview ring of the Windows Insider Program for a full month before releasing it in late May. The firm finally released the update to everyone today, but it still has some known issues.
There are 12 known issues in total, with three listed as 'investigating' and nine listed as 'mitigated'. There are no issues listed as resolved.
Here are the issues listed as 'investigating':
- Display brightness may not respond to adjustments
Microsoft and Intel have identified a driver compatibility issue on devices configured with certain Intel drivers.
- Duplicate folders and documents showing in user profile directory
If known folders (e.g. Desktop, Documents, or Pictures folders) are redirected, an empty folder with that same name may be created.
- Audio not working with Dolby Atmos headphones and home theater
Users may experience audio loss with Dolby Atmos headphones or Dolby Atmos home theater.
There are the issues that are listed as 'mitigated':
- Intel Audio displays an intcdaud.sys notification
Microsoft and Intel have identified an issue with a range of Intel Display Audio device drivers that may result in battery drain.
- Error attempting to update with external USB device or memory card attached
PCs with an external USB device or SD memory card attached may get error: "This PC can't be upgraded to Windows 10."
- Older versions of BattlEye anti-cheat software incompatible
Microsoft and BattlEye have identified a compatibility issue with some games that use older versions of BattlEye anti-cheat software.
- Unable to discover or connect to Bluetooth devices
Microsoft has identified compatibility issues with some versions of Realtek and Qualcomm Bluetooth radio drivers.
- Night light settings do not apply in some cases
Microsoft has identified some scenarios where night light settings may stop working.
- Cannot launch Camera app
Microsoft and Intel have identified an issue affecting Intel RealSense SR300 or Intel RealSense S200 camera apps.
- Intermittent Wi-Fi connectivity loss
Some older devices may experience losing Wi-Fi connectivity due to an outdated Qualcomm driver.
- AMD RAID driver incompatibility
Installation process may stop when trying to instal [sic] Windows 10, version 1903 update on computers that run certain versions of AMD RAID drivers.
- D3D applications and games may fail to enter full-screen mode on rotated displays
Some Direct 3D (D3D) applications and games may fail to enter full-screen mode on rotated displays.
Some of these issues are more notable than others, and some won't be fixed. For example, the only fix for older versions of anti-cheat software being incompatible is to get newer anti-cheat software, and that's up to the game developer to fix.
Windows 10 version 1903 has been serviced several times while sitting in the Release Preview ring, so it's in much better shape than previous feature updates. It will continue to be serviced at least once a month for 18 months.
