Windows 10 Optional Update #?
 

Windows 10 does not currently allow access to optional updates. They plan to bring this feature back in the Spring 2020 update. Until then we need to know the update name / number to find it and manually install it. Please provide the information for this update because it seems to provide critical fixes for multi-GPU users.

Hello,

OS optional updates are available via clicking Check Updates in Settings. Updates are cumulative. The multi-GPU issue was an optional update from 30th August which became part of the critical update the second Tuesday of September. We've tested and received unanimous feedback this was fixed.
Optional driver updates are manually available through Device Manager.

Unfortunately, I will not be able to comment on what Microsoft might release in the future as I have to respect our non-disclosure agreement.

Kind regards,
Alban
