greyed out Device Performance and Health option

15063.13 here, and I too was puzzled about there being no report available. Apparently I just had to wait for it to get round to doing a scan...

If you leave the PC on then it seems it will automatically go into some scan mode. Mine took around 20 minutes of constant disk thrashing (well SSD but the light was pretty active). The unknown driver is a fingerprint reader (Dell Vostro Laptop) that had no W8.1 or W10 support.

I have the same device driver recommandation. It says here that drivers update is not enabled. I didn't touch that. Otherwise, it is the fourth consecutive day that Defender (WDSC) runs ok and I'm getting updates pretty fast. I don't use the old interface anymore, plus RS-2 runs very, very well.
Cheers,

Is there any way to reset the ? Mine is alerting me to turn down screen brightness to save the battery. Thanks for the advice. How can I clear this to get the green checkmark in that status bar instead of the alert?

it's working fine now just had to let the system be for a couple days so it would have something to work with is all

Very good question San Martino! .......Brightness parameters are disable here. So, check for the battery or brightness parameters if you have a laptop or not?

Thanks for the response. It is my laptop I am talking about. I already have power plans that adjust the brightness depending on whether I am on battery or plugged into AC. I know how to adjust the battery, power and brightness in settings. Where are the parameters that you reference? I would certainly like to disable them for brightness.

Where I have my brightness set should be of no concern to Windows Defender. I want to be able to tell it "Thanks for the advice, now f#ck off."

It is just a minor annoyance. I have to manually open up Defender to be sure the definations have been updated since the green checkmark no longer shows because Defender doen't like my brightness settings.

@San Martino
There is no relation between updates and health report. Always get new defenition manually. Power plans are set to high performance here, it is a desktop. The brightness adjustment is set to 100% and night light is off. You have a laptop and you may have to live with the health report.

Will see when my cousin will upgrade next week if he gets the message that indeed is a minor issue. I also have a health report concerning Edge. Some switches are disable because I'm not using it. Nothing I can do...

All the best,

Mine still won't show up, I have updated to CU 2 days ago

Thanks Mike! That's what I figured. Severeal users have asked the same question over on the official Microsoft® Answers forum. One guy is getting the alert because he has his PC set to never sleep. I haven't even checked Edge yet since the Creators Update. I assume once I open it and customize the settings I'll be getting an alert for it as well.

Thanks again!
