I’ve been struggling with this whole dark Windows mode thing ever since the option came out. And let me tell you something: it seems easy, but it’s like wanting to paint a house and then having the walls come out a different color.
The other day a colleague called me. “Dude, I’ve got it set to dark mode and File Explorer still shows up white.” And that’s where the mess begins.
It turns out that if you have an old version of Windows 10, 1803 to be clear, dark mode doesn’t paint the whole system . It only paints the basics. And even though you see it in Personalization > Colors and you hit the button, Explorer just stays happily white.
People think it’s a bug, but Microsoft, being Microsoft, took forever to extend the black to all windows. It wasn’t until build 17650 that it started working properly . And that was years ago, but if you don’t update, you’re screwed.
Alright, let me explain the quick trick that always works for me.
You go to Settings, which you open with Windows + I, then to Personalization, then to Colors. Where it says “Choose your mode,” you hit Dark and that’s it . But watch out, because if you want to get fancier, there’s a “Custom” mode. That lets you set the system to dark but apps to light, or the other way around . I use that when I have to work with old programs where you can’t see a damn thing with a black background.
But there’s a detail that almost nobody mentions.
Sometimes dark mode doesn’t apply properly because you have a high contrast theme enabled in Accessibility . It’s like having two layers of paint fighting each other. If you see that the black isn’t black, or that some texts show up white on white and you can’t read anything, check there. Accessibility > Contrast themes, and make sure it’s turned off.
Mind-blowing, right? That something so simple has all these complications.
I’ve come across cases in forums of people running sfc /scannow to fix it . And yes, sometimes it works. Because if the system files are corrupted, the theme doesn’t load properly. But come on, the right thing is to keep Windows updated, because with each new version they patch parts that used to stay white.
Now, if you have Windows 11, things change. And don’t think everything is solved.
Because in Windows 11, the Control Panel interface, the one that looks like Windows 98, still mixes light and dark . It’s a bit shabby, honestly. We’ve been asking for a proper dark mode for years, and Microsoft is now expanding it in the Insider versions, but for the average user, it’s still not perfect .
And then there’s scheduling it.
You want it to turn on automatically when night falls? Well, in Windows there’s no native option . I don’t know why, because on phones you have it even on the cheapest models. Here you have to rely on programs like Auto Dark Mode from the Microsoft Store. I’ve tried it and it works well, but it’s a patch.
If you’re one of those who uses downloaded themes, you can mess things up too.
There are people who download third-party themes that are applied with a .theme . If you double-click that file, it changes everything. But if you then try to set dark mode from settings, they might clash. The best thing, if you like one of those themes with northern lights or black cars, is to install it and then adjust the colors from settings to your liking .
And watch out for this: if you have an OLED screen, dark mode saves you battery . Because black pixels literally turn off. It’s like your screen is resting. On LCD you don’t notice the difference as much, but on OLED it’s another world.
What annoys me the most is when an update messes up your settings. It happened to me with 22H2: suddenly, the black color had disappeared from the options . And the solution was to set it to custom mode and adjust the Windows and app modes separately.
My advice, if you want everything to actually look black, is this:
- Update Windows until it hurts.
- Go to Personalization > Colors and set dark mode.
- If you see something isn’t painted, switch to custom and try combinations.
- Restart Explorer from Task Manager . Sometimes that wakes it up.
And if nothing works, you’re left with the extreme options.
Because there are people who go straight to the C:WindowsResourcesThemes folder and run the dark.theme file directly . That’s like forcing the machine, but watch out, that file doesn’t exist in all versions.
In the end, dark mode is a silly thing, but when you work many hours in front of the screen, you notice the difference. Your eyes thank you for it. But don’t let them sell you on the idea that it’s just flipping a button and that’s it. It has its tricks, its versions that don’t support it well, and its corners of the system that refuse to stop being white.
If you decide to set it up, be patient. And if you see that some window stays white, don’t stress, because it’s probably not your fault.
