Microsoft has just released another optional cumulative update for its latest Windows 10 2004 version.
This update was released under KB4568831 and fixes a couple of issues that were causing upgrade blocks for many Windows 10 devices.
The first fixed issue was related to problems with connecting to more than one Bluetooth device when certain Realtek drivers are used. The other fixed issue is related to problems with the variable refresh rate on devices with Intel iGPU. Once the variable refresh rate was enabled on affected devices, the VRR was not working for games that are using DirectX 9.
Microsoft has also said that it plans to fix the issue when older drivers for Nvidia GPUs are used, meaning all drivers below v358.00.
And while some of the issues have been fixed by the company, Microsoft introduced a new issue that was discovered and being investigated. Devices with applications or drivers that are using certain versions of askfridge.sys or aksdf.sys could have issues with updating or restarting.
If your system was affected with the above-mentioned issues, you can now force the update and immediately afterward install this optional update. If you’re not in a hurry, that you could just wait for the upgrade blocks to be lifted during the next month.
