Win10_BrightnessSlider places an icon in your taskbar to quickly change your monitor brightness anytime.Our review and the single screenshot is a testimony to how simple Win10_BrightnessSlider is in use and functionality.If you find yourself changing screen brightness frequently and are looking for a free, portable, unobtrusive app, then look no further. Just run Win10_BrightnessSlider.exe, and you'll be able to click the tray icon and drag the slider from 0-100% brightness. Otherwise, you can exit or run at startup. That's about it.We did run into an unhandled exception that appears to be related to Microsoft .Net so be sure you have the latest Microsoft .Net installed. Otherwise, click on continue and the app will work fine.
