10ThemeFor11

Note

This theme is about 50% complete. To track its progress, check the "Theme Progress" issue. When most assets are completed, a proper theme will be provided in releases.

10ThemeFor11 is an .msstyles theme for Windows 11 that aims to provide accurate Windows 10 controls, to the greatest extent that Windows 11 allows.

Installation

First, you need to install a UxTheme patcher to allow custom .msstyles themes since Microsoft locks them out by default. Some options include the Windhawk mod UXTheme hook and SecureUxTheme.

This theme has only been tested using the UXTheme hook Windhawk mod.

1. After patching UxTheme, download the latest release of the theme from Releases (10ThemeFor11.zip).
2. Extract the downloaded zip and place the contents in C:\Windows\Resources\Themes.

The file structure should resemble this.

• C:
  • Windows
    • Resources
      • Themes
        • 10ThemeFor11
        • 10ThemeFor11_Dark.theme
        • 10ThemeFor11_Light.theme

3. Either double click one of the .theme files from within the Themes folder or select your desired theme from within Windows settings.
4. The theme comes bundled with the Windows 10 wallpaper and accent color, but if you would prefer to use your own wallpapers or colors you can override anything through Windows personalization settings.

Recommendations

I recommend using the Disable Rounded Corners on Windows 11 Windhawk mod. As most Windows 10 controls have sharp corners, having rounded windows can look strange.

Why not use the stock Windows 10 aero.msstyles file?

While the stock Windows 10 .msstyles theme works on Windows 11, it is only partially compatible. For example, the context menus and animations are broken. 10ThemeFor11 uses the assets from the stock Windows 10 .msstyles but reformats them in the way Windows 11 expects.
