With the Creators Update, Windows Defender graduated from a virus checker to a full PC health application, which is, of course, upsetting many Windows 10 users.
The issue is Microsoft’s Battery Life Recommendation, which is riling up OCD users who prefer a perfectly clean bill of health on their checkbox list and not having an icon with a persistent warning badge in their system tray.
The problem is Microsoft sees screen brightness at 100% as a battery drain issue, and would prefer users set their brightness lower, a reasonable suggestion when most battery run down tests have the screen at 50% brightness.
Of course, if you keep your laptop plugged in 90% of the time, like most users, the warning is worse than useless, and a perfect example of Microsoft nannying nagware, causing one unfortunate Reddit user to flee to the open arms of the Linux community.
A less drastic solution is to set your brightness slightly lower (apparently 99% of perfectly fine), but like everything Windows 10, as Microsoft strive to turn our PCs into appliances we are sure it won’t be long before Microsoft send power users into a panicky flurry once again.
