; done - log off and back on to see changes

edit: nevermind, I ran the reset .reg and pitch_black_theme.reg again and it's fixed. I think I accidentally ran both pitch_black_theme.reg AND pitch_black_theme_solid.reg when I initially installed this system. My bad :-D.

I'm running this .reg (once again :p) on Win11 IOT LTSC 24H2 and some UI elements have both the text and background black, any solutions?

is this still working for 24h2 win11?

is this still working for 24h2 win11?

they seemed to of changed a bunch of colors in a recent windows update so i dont think so for now

W11 Pro Workstation, 23H2, 22631.4751. Anybody know how to get it working on this? Do I just run the reg files as admin?

I just installed violet verison on win 11 24h2 no issues so far and works. thanks for your work with this
made a restore point beforehand just in-case

Tested on W11 22H2, works fine, although I have a problem - "device theme" tells me I have a white theme and not a black one.

same thing on website (and probably in other apps)

It works and all but is there a way to mall system apps amoled color?

I changed to 10bpc color and noticed that the start menu is gray instead of black. In the screenshot above my post you can already see a slight difference, but for me it's even more noticeable now with 10bpc.

I had to take an actual photo to show how gray it is, because for some reason(?) it turns darker when I engage the snipping tool.

Edit: figured out why it looked a bit weird elsewhere too, this was the cause https://old.reddit.com/r/OLED_Gaming/comments/1hexre7/why_does_enabling_10_bit_colors_wash_out_the/m288oc0/
However I'd still say the start menu is not really pure black, there's a slight difference <.<

It won't let me apply any of the Registry files

works umazing on win11 25h2

Man, I've been trying to do this on my own for a little while now.

Decoding the AccentPalette is what did the trick. This works great.

However, has anyone figured out how to change the color of the active/inactive app window?

I can't figure that one out. For example, my File Explorer window title and background are still that ugly grey.

I've tried editing DWM, Explorer/Accent, Themes/Personalize, etc. and I just cannot figure this out.

This would fully complete the pitch black look I and I'm sure everyone here, wants.

AFAIK, theres no known way to change uwp/winUI app windows which is what most default windows apps use nowadays, however you can set the colors for normal apps but im guessing you already knew that (original script does that)

Closest thing i have gotten to changing uwp/winUI app titles is to use a high contrast theme but these change alot more than desired (such as adding thick borders and changing styles of ui elements in general)

(also if you are gonna try mess with high contrast themes you might wanna backup your current values, im not sure if it will revert any changes this script makes)

Guys who have "file Explorer theme black windows 11"
I searched everywhere and couldn't find it.

Hello, I am leaving a comment because as of 3/12/2026 this seems to work perfectly fine except for one issue, the window border for applications is always bright white no matter what I do including changing the setting to apply it to borders, this is kind of annoying and I was hoping maybe a fix could be implemented?

Thanks everybody for your comments. I've finally updated this gem:
-separate regs to apply preset accent: Cyan, Red, Violet (main is Grayish)
-separate regs to toggle lockscreen: default, no image, off; and titlebars: black, default
last one will do what you want @FoxFragment

Only tested it on windows 11 25H2 so let me know how much it breaks on 10
can access the previous revision from History or click here

Thank you for updating it - I've just tested it on 11 25H2 and works well!

I feel stupid but I swear no matter what I change the start menu is always fully solid and never transparent at all where I had managed to get it to be transparent before but everything else is perfect which is great because windows likes to randomly reset certain color settings on update for fun.
