Published: October 28, 2015

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

will this work on 1909?

smauricioandres's avatar

The problem I have is that, when installing the theme, the "close", "maximize" and "minimize" buttons do not change; neither does the start button logo change.

I will attach some images.

Is there a chance that you never installed UxThemePatcher?? That is sort of required for themes.

smauricioandres's avatar

I have UxThemePatcher installed.

Sorry if this is a stupid question, bu i followed the guide on my own PC and everything worked fine. (win 1903). Next step doing it on my SO's PC. The windows taskbar still has original windows logo, instead of circle, and some things are still white. I've tried both fixes and none worked. Please help

Really hope this is updated for 1903. Everything is pretty much broke now on this theme and it's by far one of my favourites.

Using 1903. When using the theme, clicking folders on explorer causes the whole explorer to crash and restart. Using other themes work fine as intended.

Hello! I am using 1903 and am just starting customisation on Windows after coming from Ubuntu. I don't know what I am doing wrong and the changes are not taking effect on mine. Would anyone be able to help? I made sure to use ONE as well but it seems like nothing is happening. :| This is happening on other themes too. Not just this one.

In order for themes to work, you have to install UXThemePatcher.

Also, what convinced you to come to Windows from using Ubuntu? Games? haha. Ubuntu will always be much more customizable than Windows will be.

Also, I can see you're using Firefox, and I have a theme that you can use for it here...

Make sure you check the title bar checkbox in the customization menu. :)

Also, one more thing, in the file explorer, there will be the system ribbon, you'll need Ribbon disabler to get rid of that

When it comes to theming Windows, it's much more complicated than it is in Linux. ;P

I love your job first of all but here I got som issues, any way to get rid of this unnecessary type there? Also some windows for example settings is still white?

Does anyone tried it on 1903, as 1809 is partially supported since the left navigation panel is not completely black as shown.

I have problems in the left panel with 1809, do not highlight the elements when the mouse crosses, and others issues.

And I find some instability in the system, the explorer and the programs sometimes close suddenly

It's not working for me.

Seems to work fine. The left navigation panel is the same color as the main one, but other than that, everything seems to be working.

What navigation panel on 1809?

1809 by kitorPl

Hope someone fixed that left panel and made changes to support 1809, 1903.  Penumbra 10   Windows 10 Visual Style By Scope10 D by siddh315
