Windows 10 May 2020 Update issues

On May 27, 2020, Microsoft started rolling out Windows 10 May 2020 Update to the mainstream users. Anyone who manually checks for updates can now upgrade their PC to Windows 10 version 2004.

Windows 10’s May 2020 Update (version 2004) has been in testing with Windows Insiders (a group of beta testers) for about 15 months. The first build was released in February 2019 and development process for the update ended back in December 2019.

Since December 2019, Microsoft has released several cumulative updates for Windows 10 version 2004 with numerous fixes, improvements, and tweaks, but no new features were added in the last five months.

One year of beta testing and five months of additional servicing should mean fewer bugs and improved experience for those who upgrade today, but Microsoft says that there are still a bunch of known issues in this feature update.

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.

Mouse input

Apps and games using “GameInput Redistributable” might lose mouse input/support after upgrading to Windows 10 version 2004.

In other words, 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.

A lot of these issues are pretty nasty. For example, you might have Bluetooth connectivity issues if you’ve got more than one device connected. Likewise, you could run into a Blue Screen of Death if you use affected audio drivers, older Nvidia GPU driver or when you unplug Thunderbolt dock.

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