In Windows 7 and Windows XP it was very easy to change the default background color of all windows to whatever you want. Staring at white window backgrounds all day is hard on the eyes. Once changed, ALL windows of all apps would conform to the custom color as long as the apps allowed the windows bg to be invoked. So for example it worked great in Notepad and many other apps.

Then the geniuses at M$ decided that this feature was no longer needed in Windows 8, and removed it. There were some reg hacks, but nothing standard. I remember reading that the feature would be coming back in Windows 10, but I'm not finding this to be the case. The only [partial/broken] way I have found to be able to do this is to tweak the following registry keys:

[HKEY_CURRENT_USER\Control Panel\Colors]
"Window"="227 221 191"

[HKEY_CURRENT_USER\Control Panel\Desktop\Colors]
"Window"="227 221 191"

When I changed those keys to my chosen soothing color and rebooted, it worked ONE TIME. After every reboot thereafter, all the white backgrounds are back AND YET those registry keys still have my custom RGB codes. I really hate Microsoft right now, but that aside, is there any solid way to change windows 10 bg colors and make it stick?

Important: In Settings -> Personalization -> Colors, none of that changes windows backgrounds. Already tried.

I am using Windows 10 Enterprise Version 1511 Build 10586.3.

UPDATE: I rebooted again and the bg colors work correctly...but later in the day all the window bgcolors were back to white again. Windows 8.1 had the exact same bug. My conclusion is that the reg hack "works" but only intermittently. Is this simply a MS bug? Or is there a better answer/solution?

What build of Windows 10 are you using specifically? – Ramhound Nov 19 '15 at 17:05

Check out the link below it might help you out… – Shabbir Rao Nov 19 '15 at 17:21
Note: I rebooted again and the bg colors work correctly this time. I have little confidence that it will stick, including after new reboots. But here's hoping. – SweatCoder Nov 19 '15 at 17:46
If you don't want to twiddle with the registry yourself, then try "Winaero Tweaker". Any changes it makes, stick. As a bonus, it has many other useful tweaks. – Rohit Gupta Nov 20 '15 at 0:53

Apologies for the late answer. It had completely skipped my mind.

I haven't tested this solution thoroughly but it seems to do the job. You'll need to switch to a High Contrast theme for this to work. After you apply the theme, Windows should look like this:

Windows 10 High Contrast Black Theme

Context Menus and Metro UI apps are also affected:

Windows Notepad High Contrast Black Context Menu Windows 10 Settings App High Contrast Metro UI

If you use Google Chrome for web browsing, it'll prompt you to install the High Contrast extension after you apply the High Contrast theme so you can also browse the web in high contrast. You can also use the extension without enabling High Contrast mode.

As @Unsigned mentioned earlier, enabling High Contrast may change the look of several UI elements.

If you still want to enable High Contrast mode, you can copy the following into Notepad and save it as a .theme file and double-click on it to apply it.

DisplayName=High Contrast Black

[Control Panel\Colors]
Background=0 0 0
Window=0 0 0
Menu=0 0 0
InfoWindow=0 0 0
WindowFrame=0 0 0
AppWorkspace=0 0 0
ButtonFace=0 0 0
ButtonHilight=0 0 0
ButtonLight=0 0 0
HilightText=255 255 255
Titletext=255 255 255
WindowText=255 255 255
ButtonText=255 255 255

[Control Panel\Desktop]



I'm not sure if every one of those entries is necessary, so feel free to experiment. I found some information on the color section here, if it helps.

If you do not want to enable High Contrast mode and only need to change the background window color from white to something else, you can use this theme instead:


[Control Panel\Colors]
Window=227 221 191

[Control Panel\Desktop]



Just copy that to into Notepad and save it as beige.theme and double click on the file to apply the theme. Windows should look like this after you apply it:

Windows beige window background

You do not have to enable High Contrast mode or save the theme file to a particular location for it to work. Make sure that %SystemRoot%\resources\themes\Aero\ contains a file named AeroLite.msstyles.

Vinayak, will this high-contrast theme allow me to change the background color to something other than black? I don't want black, and in fact it's not really a high-contrast theme that I want. I want a background color that is somewhat beige, and all font colors just windows default, etc. – SweatCoder May 21 at 17:21
@SweatCoder Something like this? – Vinayak May 21 at 19:07
@SweatCoder I used the RGB values in your question and it looks like this. – Vinayak May 21 at 19:14
Wow! This looks promising. Would you mind editing your answer with my RGB values (227 221 191), and give exact steps to apply it? I get saving the file from notepad, but does it need to be in a certain location first? Do I have to switch to High Contrast before applying the new theme? How is it applied exactly? Etc. Etc. I'll award your answer as soon as I can repro and get this working on my PC. Thanks! – SweatCoder May 22 at 2:00
@SweatCoder I edited my answer. There's nothing special about applying the theme. You only need to double click on the .theme file to apply it. – Vinayak May 23 at 9:28

I change it via going through this blog and this one.

  1. First, open a File Explorer window and navigate to C:\Windows\Resources\Themes.  Select the “aero” folder, press Ctrl+C to copy it, and then immediately press Ctrl+V to paste it and make a copy of it.  Click “Continue” to the UAC prompt.  Select “Do this for all current items” and click “Skip” when you see the File Access Denied window.

  2. You’ll get a folder named “aero - Copy”. Rename it to “color”. (It doesn’t have to be “color”, but we’ll be using color throughout here — you just need to use a consistent name.)

  3. Go into your new folder.  You’ll see a file named “aero.msstyles”.  Rename it to “color.msstyles”.  Click “Continue” when you see the UAC prompt.

  4. Next, open the “en-US” folder and you’ll see an “aero.msstyles.mui” file.  Rename it to “color.msstyles.mui”.  When you see the UAC prompt, click Continue.

    The “en-US” folder may have a different name if you’re using a different language edition of Windows.

  5. Go back to the main Themes folder and you’ll see a file named “aero.theme”.  Select it and copy it by pressing Ctrl+C.  Switch over to your desktop and press Ctrl+V to paste a copy of the file there.  Rename the new “aero.theme” file to “color.theme”.

  6. Right-click the “color.theme” file, point to “Open With”, select “Choose another app”, and open it with Notepad.

  7. Scroll down in the file and locate the line under [VisualStyles] reading


    Replace it with


    Save your changes and close Notepad afterwards.

  8. Select the “color.theme” file and press Ctrl+X to cut it.  Go back to the C:\Windows\Resources\Themes folder and press Ctrl+V to paste it here.  Agree to the UAC prompt when you’re done.  You now have a theme that can use colored window title bars.

  9. Activate the Theme —  Double-click the “color.theme” file to activate your new theme. Windows will switch to the “color.theme” file and your window titlebars will immediately become colored.

  10. Pick a Custom Color —  As on Windows 8, Windows automatically chooses an “accent color” from your desktop background by default.  But you can set your own custom color.

  11. Right-click the desktop and select “Personalize”, or open the Settings app and select “Personalization” to find these options.  Pick the “Colors” category.  Disable the “Automatically pick an accent color from my background” option and you’ll see a list of different colors you can use.

  12. This list is still a bit limited compared to the Color and Appearance options in Windows 8.1, which allowed you to select any color you liked. This desktop control panel has been completely hidden in Windows 10.  However, you can still access it — for now.

  13. To access this hidden control panel, press Windows Key+R to open the Run dialog. Copy-and-paste the following line into the Run dialog and run the command:

        rundll32.exe shell32.dll,Control_RunDLL desk.cpl,Advanced,@Advanced

    The “Show color mixer” option here will let you pick any color you want for your window title bars.

Nice edit, much better ;) – DavidPostill May 3 at 8:25
@SweatCoder I think I could help you with that. I'll write up an answer later today. – Vinayak May 9 at 9:09
@Vinayak I'm anxiously awaiting. :-) – SweatCoder May 19 at 13:50

High Contrast themes allow you to change the default window background, as well as default text/selection colors, system-wide.

The downside is that High Contrast-type themes also change the appearance of various UI elements, as well as disable certain customization options (such as lock screen spotlight images.)
