After the latest Windows Update, brightness control and custom keyboard shortcuts no longer function

Acer 1810TZ

64 bit OS and processor (4GB)

Windows 10 Pro

Version 1803

Build 17134.48

Installed 05/17/2018

Quality Updates Installed

• KB4103729
• KB4103721

Definition Updates Installed

• KB2267602

Like the subject says, I've lost brightness control as well as custom keyboard shortcuts I had setup to start programs (Ctrl + Alt + [letter]). I just discovered the latter not working. Brightness control no longer works with function key shortcut, icon
in the notification panel, or adjusting the brightness slider in Settings.

Note that Windows key shortcuts DO work. Volume control DOES work with function key, system tray icon slider, etc.

I've tried the following to no avail:

• updating display and monitor drivers as well as switching to the basic Microsoft display.
• uninstalling update
• reinstalling the update
• the old voodoo trick of rebooting at each of the above steps

I'm at a loss as to what to try or what to even what to search for at this point. Thanks for your help!
