Windows 10 10056: Turning on custom color themes, yellow is a bad choice

In the latest leaked build of Windows 10, 10056, there are new theming options but when you try to adjust them in the Settings app, it crashes. But, if you are willing to tweak your registry, you can have a little fun and change the theme color for the taskbar and the Action center.

Before we go any further, making changes to the Registry is a risky place to play around if you are not familiar with the feature. If you accidently delete something or adjust the wrong setting, it can cause your machine to not boot; proceed with caution. To turn on the feature, add the following DWORD, ColorPrevalance, to HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Themes\Personalize

For those of you who do not want to tinker with the Registry or do not have build 10056 installed, you can check out the gallery below.

There is also a way to turn on the dark theme as well but it only seems to change the background color of the Settings app. By adding SystemUsesLightTheme with a DWORD of 0 to the same location, you can recreate the screenshot you see below.

I haven't tried making these change on other builds of Windows 10, so if you have an older version installed, let me know in the comments below if these changes worked for you.

Thanks for the tip Vitor!
