try it now...

import ctypes as ct from tkinter import *

root = Tk() root.update() root.iconify()

DWWMA_USE_IMMERSIVE_DARK_MODE = 20 set_window_attribute = ct.windll.dwmapi.DwmSetWindowAttribute get_parent = ct.windll.user32.GetParent hwnd = get_parent(root.winfo_id()) renduring_policy = DWWMA_USE_IMMERSIVE_DARK_MODE value = 1 value = ct.c_int(value) set_window_attribute(hwnd, renduring_policy, ct.byref(value), ct.sizeof(value)) root.update_idletasks()

root.deiconify() root.mainloop()

Doesn't work.

try this one if it doesn't work then minimize the window and maximize it if u r getting any error then pls tell me...

import ctypes as ct
from tkinter import *

root = Tk()
root.update()
root.geometry("600x400")
root.config(bg="#222")

DARK_MODE = 20
set_windows_attribute = ct.windll.dwmapi.DwmSetWindowAttribute
get_parent = ct.windll.user32.GetParent
hwnd = get_parent(root.winfo_id())
value = 2
value = ct.c_int(value)
renduring_policy = DARK_MODE
set_windows_attribute(hwnd, renduring_policy, ct.byref(value), ct.sizeof(value))

root.mainloop()

This worked, but how can I make it so its black all the time. Bypassing peoples custom accent color.

Yes write after the geometry add this root.iconify()
root.update()

Then at last before the root.mainloop add this
root.deconify()

Then it will work properly...

You can install the pywinstyles module for Windows 11 and go through it on pypy website and search this module "pywinstyles". You can customise the Windows very beautifully through it go to the project description thoroughly then u will understand after watching the pics...
