My caveat was only meant to say I've never used any of those keyboard LED indicator apps so I'm not in position to recommend (or not) any of them. I have no need for them because the keyboard LEDs on both my Dell desktop and Dell laptop don't turn off automatically. The 2nd link I posted is to Vovsoft's app. This app is also available for download at the CNET and ZDNet sites, both very reputable companies, if that means anything to you... The only way to get around the LEDs turning off automatically nowadays would be a firmware or software update for the keyboard. Dell doesn't make them, so it's up to their supplier to implement such changes. This is all being done to save energy and extend battery life, but at the inconvenience and annoyance of users. As for driver updates, are you logged into an account with administrator privileges when trying to install them? Sometimes, you have to disable your anti-viral app before installing them (be sure to re-enable it immediately afterward!). Some driver installers give an uninformative error message when it really meant to say the version attempting to be installed is the same or older than the driver that's already installed. Intel driver update are notorious for this. So compare installed driver version numbers in Device Manager with the version you're trying to install. Go only by the driver's version number, not by date(s). If it's the same or lower version number, don't bother with it.
The keyboard on my wife's new 7700 AIO has an indicator light that reflects the status of CAPS LOCK/NUM LOCK when toggled,  However, the indicator light only stays on for about 3 seconds.  Pretty useless.On her previous [HP] desktop with Windows 10, she would get a momentary on-screen popup that would display the key status.  It was helpful, but it too disappeared after a few seconds.Can we/is there a way to configure the hardware/software to generate a permanent key status indicator on the Windows taskbar?
