As future Windows 10 feature updates are released it will introduce incompatibility with older devices and PC's. Certain components will not support these changes as observed by some users not seeing transparency anymore or brightness functions missing. Recommendations include, rollback, block the upgrade or consider upgrading components in your system such as graphics, storage, BIOS, motherboard or purchase a new Windows 10 PC.
There seems to be some early adopter issues at this time with Windows 10 1803, if you can, I recommend you downgrade to your previous version until the Spring Creators Update matures with future cumulative updates.
Open Start > Settings > Update & security > Recovery > under Go back to my previous version of Windows 10, click Get started.
