Win10 version 2004 is here but… surprise!

Win10 version 2004 has been officially released.

Microsoft’s been testing it since December. We’ve been getting official notices about 2004’s status for months. The last official notice, on May 12, didn’t list any known bugs. Today’s notice, though, comes packed with all sorts of known, officially acknowledged, problems:

• Difficulty connecting to more than one Bluetooth device
  Windows 10 devices with certain Realtek drivers might be unable to connect to more than one Bluetooth device.
• Errors or issues during or after updating devices with Conexant ISST audio drivers
  Devices with affected Conexant ISST audio drivers might receive an error or have issues with Windows 10, version 2004.
• Errors or issues during or after updating devices with certain Conexant audio drivers
  Devices with affected Conexant or Synaptics audio drivers might receive a stop error with a blue screen.
• Issues using ImeMode property to control IME mode for individual text entry fields
  Some IMEs for certain langauges might have issues using the ImeMode property with certain apps.
• Variable refresh rate not working as expected on devices with Intel iGPU
  Enabling VRR on affected devices will not enable the VRR for most games, especially games using Direct X 9.
• Stop error when plugging or unplugging a Thunderbolt dock
  Devices using Thunderbolt docks may receive a stop error when plugging in or unplugging the dock
• Errors or unexpected restarts for some devices using Always On, Always Connected
  Devices with more than one Always On, Always Connected capable network adapter might have issues.
• No mouse input with apps and games using GameInput Redistributable
  Affected apps and games using both GameInput Redistributable and Windows 10, version 2004 might lose mouse input.
• Issues updating or starting up devices when aksfridge.sys or aksdf.sys is present
  Devices with apps or drivers using certain versions of aksfridge.sys or aksdf.sys might have issues updating or starting
• Issue with older drivers for Nvidia display adapters (GPU)
  You might have issues if you are using an Nvidia display adapter (GPU) and drivers with a version below 358.00.

The announcement also says:

Windows 10, version 2004 is available for users with devices running Windows 10, versions 1903 and 1909 who manually seek to “Check for updates” via Windows Update.

The wording of that is a bit strange… but it looks like this version works like the last two versions: If you go into Windows Update in Win10 1903 or 1909, click Check for Updates, and Microsoft determines that your machine is ready for 2004, you get the notification that the 2004 update it available. I think. (My production machines aren’t showing anything at this point.)

You have to click on Download and install before it’s installed on your machine. That’s what I published in Computerworld earlier this week: How to block the Windows 10 May 2020 update, version 2004, from installing. It’s also what Microsoft promises in its just-published guide How to get the Windows 10 May 2020 Update.

As best I can tell, clicking on Check for Updates in Win10 1903 or 1909 does NOT immediately upgrade you to 2004.
