Recently, I suddenly was depressed to the 2003 sluggish theme, so I wanted to change the theme of XP. Open the display - attribute - inside the theme, there is no XP theme, how will I do, I am a lazy person who doesn't want to download the theme. So I drilled into the service, haha, there is a service called "Theme" is actually disabled, it is automatic,, ok, restart, and there is XP's theme after rebooting ....
