Another positive news: Microsoft has probably fixed some older display errors like the BlackScreen bug or the missing brightness control in Windows 10 April Update (V1803).
- Addresses an issue with the brightness controls on some laptops after updating to the Windows 10 April 2018 Update.
- Addresses an issue that caused the system to start up to a black screen. This issue occurs because previous updates to the Spring Creators Update were incompatible with specific versions of PC tune-up utilities after installation
If the brightness control on notebooks is inaccessible, this is probably due to an incorrect graphics driver being installed.
