This visual style will no longer be updated.

Works on Windows 8 and 8.1. (Does not work on Windows 7)
This visual style is made to have no accent color, only black, grey and white.
The music player in the preview image is AIMP with Ladient ( )

Credit to these guys since they did most of the work.

Because of Windows 8 security, it will be very difficult,

This theme is super powerful!!!

It would be nice if you could fix Control panel white parts though, because its the only thing left to correct to make this theme best one available.
Maybe there is some kind of fix that I m unaware, I would appropriate any help if thats the case. Best regards.

The only way I know of is by using a modified shell32.dll file that has the white control panel images changed to a black. Some other Windows 8 dark themes include this in their download. I never bothered with it as it's a manual process of changing a system file that can, if done incorrectly, make your system unstable.

是的\Unable to start the system" /システムシステムを起動できません
Uki1995's avatar
Yes, I ve tried it myself and completely broke the system :)
And what is more interesting, I have done it correctly, but windows recognizes
modified files as corrupt files and it simply wont boot.

Are you running Windows 8 or Windows 10?

Try switching back to the default windows theme (aero), reboot your pc and then apply the theme again.
CHINA168's avatar
Okay, so i did what you said...It didn't work XD. 
Darn, too bad I cant use this theme, Its very minimal and unique. 
"When ya cant get what ya want, even though its simple."
Oh well, I'll find some other way I guess. But yet again thank you for the help, We'll be looking forward to your creations :)

Maybe the following patcher will work better:….

Before you install it, switch back to the default Windows theme (aero), uninstall UxStyle and reboot your PC.

This is a long shot since this has not been updated in ages.

I was wondering if you could implement the task manager colors from your windows 10 version of this skin into this one? (Could i just copy files out of the windows 10 version?) 

Also i found 2 bugs

When right clicking things like file explorer the menu is purple at one part

How do I fix the yellow bit where the title is?

Otherwise fantastic work!

Scope10's avatar
Yes, I could change the task manager colors in an update. They do look pretty bad in Penumbra 8.

The right click bug you're referring to sounds strange. Could you take a screenshot of it? I might need to install a Windows 8 virtual machine to fix it (I only have Windows 10 machines). 

The yellow bit from the title sound like a theme colorization problem. Again, could you clarify the problem with a screenshot? I will see if I can find a solution or fix.

I hope they are not problems that occurred because of a Windows update because that could complicate things.

Any chance of a Win10 port?
Scope10's avatar
Penumbra 10 is pretty much done already. I just need to change this one black text, but I can't find where the location of the property is.

I will release it in the coming days even if I don't find it, since everything else already looks how I want it to.

Great news!
Your theme is the best dark, almost from the beginning was on it in Win8.1

This theme is simplistically beautiful!
I absolutely adore it. ^^
I love this theme! But there is a black screen with the mouse and there is no login screen when i reboot or shutdown, after that i have to go to system recovery and restore from a restore point :( Please help me if you can i would really appreciate it! :)

That has to do with the way UxStyle and other alternatives patch your system in order for you to use third party visual styles like Penumbra 8.

If you look at the FAQ of one of the UxStyle patchers (for example, see… ), it will explain the problem. You basically have to temporarily switch back to the default visual style before you uninstall a program and restart your PC. Once properly booted, you can switch back to Penumbra 8 or any other visual style.
