Windows 10 Creators Update Annoys Users With Maximum Screen Brightness Battery Warnings
You do not need an advanced degree in engineering to know that cranking up the brightness on your laptop's display will shorten its battery life. That boils down to common sense. Be that as it may, Windows 10 with the Creators Update installed feels compelled to persistently warn users who max out their display's brightness level of the potential negative impact it can have. Grrr.
The warning is part of a Health report generated by Windows 10's Device performance & health section. This is actually a beneficial thing for users, especially less savvy PC owners, as it scans for issues that could impact a system's ability to function properly. Issues it looks for include missing Windows updates, up-to-date device drivers, low storage capacity, and battery life.

In the image above, you can see how Windows 10 handles systems with the display brightness turned all the way up. With the Creators Update installed, Windows 10 views this is a potential system health risk, noting that having it cranked up "can impact your device battery life."
That would be fine if Windows 10 gave users the option to dismiss the message, but that is not the case. Unless turning down the brightness level, it will show up as a potential health risk, with users forever reminded of it with an icon that appears in the system tray.
The issue here is that the warning is overzealous. Some users may prefer overly bright laptops, while in other cases we've played with laptops with screens that aren't all that bright even when set to 100 percent. And of course if you're the type who keeps your laptop plugged in most of the time, battery life might be a moot issue.
There is a solution available, and that is to lower the brightness on your laptop to 99 percent. That kind of underscores the absurdity of the warning, as it disappears when lowering the brightness level by a mere 1 percent.
