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

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.

Any way to make default the white colour in office apps with other themes?

Algoinde Featured By Owner Oct 21, 2018  Hobbyist Digital Artist
Hi! This is a great theme, thank you for you work.

I am using Aero Glass, which works with the stock Windows theme, however with Penumbra the statusbar transparency/blur is covered by the theme's gray frame. Is there any way to patch the theme with transparent window frames?
datsatthune Featured By Owner Oct 16, 2018
Stay in 1803 and wait...
alali44 Featured By Owner Oct 15, 2018
I hope this awesome theme will be updated to 1809 as soon as possible
mhp1995 Featured By Owner Nov 7, 2018  New Deviant
it works in 1809... i am using it
nzanee Featured By Owner Oct 16, 2018  New Deviant
Give him time, the theme mostly works for me using 1809 (didnt install the update that came after tho) and the workarounds to re apply the theme after restart/sleep, the only broken thing (for me) is when it turns back to white after sleep, and the command fixes it, ofcourse I'd love to not have to use it just like before, but oh well, I can bare with it for the meantime
MathiasTopKek Featured By Owner Oct 12, 2018  New Deviant
yeah it worked fine for the first update to 1809 but then they released an cumulative update and it fucked the theme up so hard.
suggesting to update asap!
AlexanderSct Featured By Owner Oct 20, 2018  Hobbyist General Artist
maybe installing ultrauxthemepatcher again would work?

It just won´t work for me. Installed everyting, wouldn´t work so i used the system recovery to jump back and install it again, still won´t work.
And I made sure I did everything correct. Please help me im desperate for that gorgeous theme.
AlexanderSct Featured By Owner Oct 20, 2018  Hobbyist General Artist
It might only be working for me, but try installing ultrauxthemepatcher again.

Me too :(
skuffer Featured By Owner Edited Oct 11, 2018
Been using Penumbra on Windows 10 for quite some time now and absolutely love it, However recently Chrome introduced quite the update and made the URL bar background white again.

I've tried everything I know of to get it dark but it just won't work, Does this need to be updated to support the new Chrome update? Thanks Scope

Here's a few examples of it below (including new tab also)

uffjohn Featured By Owner Oct 12, 2018
Navigate to chrome://flags/, find the setting "UI Layout for browser's top chrome", and change to "Normal". Should do the trick.
skuffer Featured By Owner 5 days ago
On the newest Chrome update it breaks it once again :l Any ideas on how to get the URL bar black again? (I didn't even mean to upgrade Chrome either)
skuffer Featured By Owner Oct 20, 2018
Thank you so much this fixed it! You're awesome dude

Just letting you that it works great with new October Update

umosay Featured By Owner Edited Oct 5, 2018
Can you try going into file explorer, where it lists all your main drives - then turning on preview pane with alt + p and see if you can access any drives without explorer crashing. That's the only issue I'm having. Doesn't happen with other themes or with preview pane disabled.
nzanee Featured By Owner Oct 4, 2018  New Deviant
So, by reading the comments below... does it work with October Update (without crashes and that kind of stuff) or not?..
umosay Featured By Owner Edited Oct 5, 2018
Works for me, the only explorer crash appears when I click on the main file explorer window with drives, if I just navigate it through other folders it's fine. Crash might just be for me though, it doesn't always happen but something must trigger it.

-e- OK I think I know what is causing my crashes now. When I have preview pane enabled (alt + P) it restarts explorer on the main FE page. Doesn't happen if already inside a drive. Doesn't happen with other themes. Someone else should test that too.
VagJayJay Featured By Owner Oct 4, 2018
It works on mine, though there are some inconsistencies within dialog boxes and stuff, but works overall.
118shadow118 Featured By Owner Edited Oct 4, 2018  Student Interface Designer
Is there a way to get the status bar with Penumbra? 

I switched to Penumbra while there was an Explorer window still open and the status bar remained, if there was an option to get something like that to be permanent, that would be great

umosay Featured By Owner Oct 4, 2018
Just uninstall OldNewExplorer
118shadow118 Featured By Owner Oct 5, 2018  Student Interface Designer
I don't have ONE installed, still no status bar. Those two little shortcuts in the bottom right corner are really useful
VagJayJay Featured By Owner Oct 3, 2018
Just a heads up bro, you might not have to overhaul everything for October update. Got the update last night, along with the latest UXThemePatcher, after everything, Penumbra worked fine (All variants, even the alternate version).

Attached is an image which shows how the theme looks along with the version of windows that i am running.

Build 1809 is being installed right now. A big request to update your beautiful theme to this version as soon as possible.
Scope10 Featured By Owner Oct 3, 2018  Hobbyist Interface Designer
Thanks for the heads up. This weekend I will set time aside to see if there is an easy way to transition the theme in order to support the October 2018 update version 1809. If there isn't, I will either have to wait some more for an easy fix or rebuild the theme using the new theme file (which will take some time).
umosay Featured By Owner Edited Oct 3, 2018
Theme looks to be working the same as it was for 1803 for me, thought it didn't work properly the first time. I just reinstalled the latest uxthemepatcher and reapplied and it worked. Running windows dark mode and it doesn't seem to be affecting it so far, just looks a little different in explorer down the left.

-e- spoke too soon, getting some explorer crashes
JokerTheJoke Featured By Owner Oct 3, 2018
Does your theme already support Win 1809? It is already rolling out.
UXThemePatcher got updated the day before yesterday, although it's changelog hasn't been updated.
datsatthune Featured By Owner Oct 3, 2018
Same question
JokerTheJoke Featured By Owner Oct 3, 2018
I just tried it.
While it did not brake anything, it does seem to do nothing. At least the window borders and control center is still white. The explorer has this ugly MS dark theme which just looks totally unaesthetic. Scope did a MUCH better job with it than MS.
Does anyone else have a weird brownish tint in the bar at the bottom of the dark explorer?
Scope10 Featured By Owner Oct 3, 2018  Hobbyist Interface Designer
I have not tested it yet, but according to other themers, the new Windows 10 Dark Mode seems to be causing some of the issues that you described. This weekend I'll see what I can do.
JokerTheJoke Featured By Owner Oct 5, 2018
I just tried it again because I read here that Old New Explorer causes problems.
It works now. The background of the explorer seems a little lighter and the selected entries in the left pane are not highlighted. Didn't notice any other differences yet.
Someone said that it crashes when you select a drive but I can't replicate that.
