The themepack (popularly known as a theme) feature was first introduced with Windows 7 and has been part of the latest Windows 10 version as well. A theme or themepack usually includes a bunch of beautiful wallpapers and a color for the window borders. Some themes or themepacks also include desktop icons, screensaver, and sound scheme. A themepack or theme is not easily accessible as right-clicking on desktop and clicking personalize option no longer brings the classic Personalization window in Windows 10. That said, a similar version of the Personalization window is present in the Settings app, and can be used to create, install, change, and delete themes. We have already shown how to change the default theme in Windows 10 as well as how to create your own theme in Windows 10. In this guide, we will see how you can download, install, and delete themes in Windows 10.
