2. The Personalization dialog box pops up. The following topics are installed and included on your computer. If you want to replace it, just click and select it.

3. But what if I want to download and install more themes? First, make sure that the computer is online. Look at the right side of the dialog box, and then click Get more topics online.

Pop up a webpage and go to Microsoft's WIN7 theme website, where you can download your favorite theme online.

5. After finding the theme, click "Download" to pop up a dialog box, and you can save it on your desktop. Because the downloaded file still needs to be installed, you can delete the installation file after installation.

6. On the desktop, double-click the file and it will be installed. You can find him in the personality dialog box. The theme is also changed to the theme just downloaded.
