Windows 10 May 2020 Update Could Create Trouble for You

Known Issues in Windows 10 May 2020 Update (version 2004)

As of May 27, 2020, Microsoft is aware of at least ten known issues in Windows 10 version 2004. The company acknowledged the known issues with the feature update in multiple support documentations.

Bluetooth Connectivity Issue

Windows 10 May 2020 Update could prevent some users from connecting or pairing more than two Bluetooth devices at a time. This bug could also prevent you from using Bluetooth mouse, keyboard and headphones or other Bluetooth devices at the same time. Bluetooth connectivity issues in some installations of Windows 10 with unknown versions of Realtek Bluetooth radios.

May 2020 Update has already been blocked on devices with problematic Bluetooth drivers and Microsoft warns that users should not force the update with the Media Creation Tool until this issue has been marked resolved.

Conexant ISST Audio Drivers

A new known issue with Conexant ISST audio drivers. According to Microsoft, incompatibility issues with certain versions Synaptics’ Conexant ISST driver could prevent Windows 10 version 2004 update on affected machines. The bug appears to be hitting audio drivers named “Conexant ISST Audio” and “Conexant HDAudio”.

Conexant Audio Drivers

Another bug with Conexant audio drivers might cause a Blue Screen of Death error after installing Windows 10 feature update.

ImeMode

There is a bug where apps might have issues if they utilize the ImeMode property to control Input Method Editor.

An IME is a program that enables users to enter complex characters and symbols, such as Japanese Kanji characters, using a standard keyboard. The ImeMode property is typically set to ImeMode.Off for a TextBox control that is intended to only enter numeric values. The ImeMode property value is set to ImeMode.NoControl for the Form class.

Most classes that do not directly support Input Method Editors, or allow direct input from an IME, will set the value of this property to NoControl.

Variable Refresh Rate

The update could create trouble for you if have a monitor with Variable refresh rate (VRR) plugged into an Intel integrated graphics processing unit display adapter. Windows 10 will not enable the VRR for most games if you have VRR plugged into iGPU adapter.

Thunderbolt Dock and BSOD

Devices with a Thunderbolt dock may receive a Blue Screen of Death error when plugging in or unplugging the dock.  (My laptop is a Thinkpad T430, with a Thunderbolt dock – not doing the update until this bug is fixed.)

Unexpected Restarts and Shutdown

Windows 10 version 2004 could cause a random shutdown and restart on devices with a network adapter that supports “Always On, Always Connected” capability.

Surface Pro 7 and Surface Laptop 3 are also affected and Microsoft says it has already placed compatibility hold on these devices.

Mouse Input

Apps and games using “GameInput Redistributable” might lose mouse input/support after upgrading to Windows 10 version 2004. This nasty bug might prevent you from using your mouse to interact with certain apps.

Broken Apps and Drivers

Windows 10 May 2020 Update could also break apps and drivers with affected versions of aksfridge.sys or aksdf.sys. When Windows 10 detects aksfridge.sys or aksdf.sys, apps or drivers might fail to start if you install the feature update.

BSOD on Older Nvidia Drivers

Microsoft has also warned about system failures and Blue Screen of Deaths on PCs with Nvidia GPU driver version 358.00 after upgrading to version 2004.

Microsoft says the update won’t be offered on affected devices and you should not force it with Media Creation Tool.
