Want to change how your desktop and windows look in Windows 10 and share that design with friends? Windows 10 lets you create your own theme with a custom desktop background, windows border and Start menu accent color. You can save these settings as a new theme file to use over and over or send to others.
1. Open the Start menu and select Settings.
2. Choose Personalization from the settings screen.
3. Change one or more of the following:
- Desktop background: Select picture, solid color, or slideshow. In addition to some default photos, you can click the Browse button to select a background picture. If you choose slideshow, the default album for the slideshow will be the Photos folder, but you can browse to a different folder and also set how often you want the picture to change on your desktop.
- Colors: You can either have Windows automatically pick an accent color from your background or select a color for the Start menu tiles background and the thin border around windows. This will also change the color of the Windows icon in the taskbar when you hover over it. Optionally, you can also have that color shown on the taskbar and Windows 10’s action center by checking those checkboxes.
You can also change the Lock screen background image and Start menu settings here, but these aren’t saved with your theme.
4. Click Themes in the Personalization window, then Theme settings.
This will open up the personalization settings in the Control Panel.
5. Right-click on the Unsaved Theme and select Save theme. The Unsaved Theme appears in the My Themes section and contains the the settings you just adjusted.
6. Give your theme a name in the window dialog box and hit OK.
Your new theme will be saved and you can switch between it and other themes easily by going to the personalization options in the Control Panel. Once your theme is saved, you can also right-click on it and save the theme for sharing as a .deskthemepack file.
Microsoft doesn’t offer a built-in way to create more complex themes than this (e.g., changing app icons or default sounds), but there’s an app in the Windows App Store called Theme Creator that promises to let create a complete Windows theme package. The app crashed on me when I tried it, but you might have better luck.
