Penumbra 10 - Windows 10 visual style by Scope10 Penumbra 10 - Windows 10 visual style by Scope10

Works on Windows 10 only

Supported versions:

Version 1703 (Build 15063) - Creators Update

Version 1709 (Build 16299) - Fall Creators Update

Version 1803 (Build 17134) - Spring Creators Update

Might not work on older versions

This visual style is made to have neutral colors.
The music player in the preview image is AIMP with Ladient 2 ( )

Before you install

- Check if you have the right version of Windows 10 (See…)
- Make a restore point (!)
- Install Open Sans (included in the download in the 'Font' folder)
- Uninstall any patch if you have already installed one (UxStyle, UltraUXThemePatcher) (!)

How to install

1. Install UltraUXThemePatcher and reboot after install:… 

2. Install Old New Explorer (ONE):…
My recommended settings:

3. Copy the content of 'Visual style' to 'C:\Windows\Resources\Themes' (

Right-click your desktop > 'Personalize' > 'Themes' and click 'Penumbra10(w)(s)' under 'Apply a theme'
The preview image above uses "Penumbra10" (recommended)
See "Variants" section below for information about the different theme files.

5. Done

Something wrong? Try this

- If everything is still white or mostly white, click on the 'Windows' theme, reboot your computer, and repeat step 4.

- Reinstall the latest versions of UltraUXThemePatcher and Old New Explorer (ONE) (links above). Be sure to reboot afterward.

- Check the FAQ section of the UltraUXThemePatcher website (link above) if the steps above did not fix your problem. At this point, the problem is usually because of the required system files not getting patched correctly. 

Known problems

- Some remaining white elements, like in the Task manager under Performance
- Some remaining blue elements

Known fixes

Problem: Hidden disabled text or icons (like in Notepad++)
Note: These altered themes will create minor inconsistencies in the theme.

Problem: The theme will have white elements after returning to the desktop from sleep, hibernating or locking the PC.
1. Open up "regedit"
2. Make a backup (right-click > export) of the following key/folder:
3. Now remove the key/folder [DefaultColors] (right-click > delete, may require you to Take Ownership first)
4. Done
Note: Your theme color will restore to default Windows blue after returning to the desktop. This only affects things like the lock screen colors and volume indicator color.
Alternative fix (using a scheduled task):…
Note: Instructions are in the download.

Extra customization

- To change your taskbar color/opacity…

- Bring back the old personalize window…

- Explorer window customization (Old New Explorer)…

- Center your taskbar icons…

- Bring back the command bar
    Use the following guide, but remove the line with Element padding, instead of adding it.…


Penumbra 10 comes with a couple of variants:

- Penumbra10: The theme as it was intended to be used.
If you don't know which variant you should use, pick this one.

- Penumbra10w: The w stands for "White".
This theme is like Penumbra 10, but has a white Windowcolor and black Windowtextcolor.
This is meant for people that want a dark theme, but don't want programs like Microsoft Word and Excel to be affected with a dark page and white text. This theme does create inconsistencies with the rest of the theme.

- Penumbra10s: The s stands for "Stock".
This theme is like Penumbra 10, but with stock/default looking caption buttons (Minimize, maximize, close) and Taskbar button.

- Penumbra10ws: A combination of White and Stock.


- The theme has not changed since it already supported version 1803, Spring Creators Update.
- Install the latest UltraUXThemePatcher and reboot if you're coming from an earlier version of Windows 10.
- Changed download folder structure. All abovementioned Windows 10 versions are supported by the same theme files. No need to differentiate with a different folder per Windows 10 version.

- Fixed white background in Run task dialog
- Fixed white background in Extract files window

- Fixed the no border issue. The theme now has the same border size as the default Windows theme (1px)
- Adjusted caption font and size

- Completely remade penumbra 10 with the version 1709 default Windows theme.
This means that the theme now officially supports Version 1709 (Build 16299) - Fall Creators Update.
- Certain problems, like the right-menu not showing or being bugged, should be fixed now.
- The border size is now 0px (from 4px)
     I tried to make the border 1px, but I can't seem to find the element that changes the color of the left border.
    With borders, it would show inactive windows with a translucent border and becomes opaque when the windows is active.
- Small color and asset changes

- Fixed Penumbra 10s and 10ws versions (taskbar pearl did not change)

- Updated Automated Theme Reset Script to work on Creators Update (using ThemeSwitcher now)

- Fixed the command bar on the Creative Update (it now no longer shows on mouse over)

- Added support for Version 1703 (Build 15063), also known as the Creators Update.* (separate folder)
- Fixed the unreadable searchbar text in explorer
- Increased the brightness of the right click menu
- New wallpaper

- Added two new variants: Penumbra 10s and Penumbra 10ws
The s stands for "Stock" and comes with stock/default looking caption buttons (Minimize, maximize, close) and Taskbar button.
- Removed Build 10586 (November)
- Small changes

- Added compatibility for build 14393 (Anniversary update)

- Small alignment and margin change for the explorer navbar

- Fixed copy window not showing with MTP transfers
- Changed caption buttons
- Changed the blue buttons in the copy window
- Changed the detail pane colors
- Other small changes

- Fixed build 10586 compatibility
- Fixed white in context menu
- Fixed black text problem
- Removed beta tag
- Tons of other small changes

- Initial beta release

Works in 1809. Lovely dark themes are kind to my eyes; thank you for also offering a 'white' option for apps with text boxes. That was thoughtful.
Alexb1096 Featured By Owner Apr 28, 2019  New Deviant
I like this theme but i think it has some problems.
Excel in black mode is really bad, so i'd like to use penumbra 10w but this version has a bug i think: the sidebar in "my computer" has black text and grey background. So i tried the s version but excel is in black mode. Ws versione has w version problems and s version problems so i think it's useless.
Can i create my Penumbra version?

I have Windows 10 1803.
AlKatz Featured By Owner Apr 24, 2019  Hobbyist Artist
Does it works well at 4k?
ZanderVFX Featured By Owner Apr 17, 2019
Please 1809!!
Literally the only good theme, thanks so much for making it.

My only complaint is, i wish it was darker...
caspersky123 Featured By Owner Edited Apr 13, 2019  Student Photographer
The Penumbra10w theme fix the Ms Office issue, but broke the task manager and some windows explorer font color (changed to black).

The Penumbra10s theme fix the broken the task manager and explorer  font color (changed to black) issue, but broke the Ms Office (2016).

The Penumbra10 ws doesn't fix both of this issue, any other solution?

appreciate this very much as all other theme makers seem to have gone the "paid only route"
RommieJr Featured By Owner Feb 18, 2019  Hobbyist Digital Artist
I love and appreciate this dark theme. The only thing that is not perfect for me, is black reading panes in some apps which hides the dark text, for example, in online outlook mail. Anyone know how to correct this?
tashilapathum Featured By Owner Feb 5, 2019
Pleeeease update this for version 1809. The right hand side pane looks different
Kishimori Featured By Owner Feb 4, 2019  Student Digital Artist
The best theme! Thank you so much. I'm using it on Windows 10 - Version 1809. Still no bug. But i'll report later if i encounter them.

No, it's not! Just look at my explorer on 1803. Penumbra 10 not fully support Windows 10 ver 1809, that's why i'm still use ver 1803.

Almost perfectly, I suppose. I'm not too picky really

Does it work with Windows 10 Version 1803 (Build 17134.472)?
TikiThorsen Featured By Owner Jan 4, 2019
Yes, it also works on 1809.
war-fool Featured By Owner Jan 2, 2019  Hobbyist Digital Artist
Title bars and taskbar not as described by the preview. Any suggestions? Without that, it's just a black theme..

datsatthune Featured By Owner Jan 4, 2019
Reason is Penumbra 10 not fully support Windows 10 ver 1809.

Ahh okay. Thanks!
sinsinta Featured By Owner Jan 1, 2019
What will happen to my windows system if I didn't create a restore point before installing? What should I do if I some time I want to completely undo all those things?
Shadow927 Featured By Owner Jan 4, 2019
If you did not have any problem while applying the skin such as any bsod, system error etc. you'll just have to undo the changes and you won't have Penumbra anymore.
The restore point is useful in case you had problems like I said to your pc while applying Penumbra. They could happen if you are applying it to a version of Windows 10 that's not supported yet or if your GPU most likely can't handle this skin. I have a budget gaming rig with Intel Core i5 3470 3.2GHz, Nvdia GT 1030 2GB VRAM and 8gb DDR3 Ram, this should work fine with the skin. If you have a old laptop that has been upgraded to Win 10 but with low specs then most likely it won't handle the skin and that would result in a system error/bsod. That's what system restore point is for.
CrestlineKid Featured By Owner Dec 31, 2018
Please make support for 1809 <3
goldjazz Featured By Owner Dec 16, 2018
i may be stupid as hell but i cant seem to fully install this. the upper right controls (minimize, restore down and close) seems the same and there is no background darkenning in the UI. I have followed every step tho... Can you help me?
demysek Featured By Owner Edited Dec 14, 2018
Does anyone know why is it like that? The theme is awesome!
P1 by demysek    
CrestlineKid Featured By Owner Dec 31, 2018
I agree, that should be fixed. Unless it is just a bug.
Bnuldun Featured By Owner Edited Dec 9, 2018  Hobbyist Photographer
It seems this theme didn't do much at all besides give me a new desktop wallpaper. It didn't even turn certain windows dark gray. Like, when I right click a picture and click "properties," that window is all white still. Let me see if I can upload a screenshot of it. This sucks, because everything was working before. I had a different Steam skin and I did something that I don't even remember honestly. I was messing around with my themes for some odd reason. Anyway, here's the screenshot of a white window. Other random things are still white as well. I just thought I'd try this theme.

Edit: Never mind. I got it to work. I used the UXPatcher again and it worked. All is well again.
