After installing or upgrading to Windows 7, you may notice that the AutoPlay dialog does not list Windows Media Center as one of the options.
This is the case when you open Change AutoPlay settings applet in Control Panel.
Windows 7 does not seem to include the Windows Media Center AutoPlay registry entries by default. However, you can add the necessary entries manually or export the keys from a Windows Vista PC (which is what I did). The AutoPlay entries are populated from this registry branch:
Tip: Keys and Values starting with the word "EHome" (EHomeDVDDropTarget, EHomeMusicDropTarget, EHomePhotosHandler, EHomeSVCDDropTarget, EHomeVCDDropTarget, EHomeVideosHandler) are the ones we need.
I’ve made available a REG file which adds all of the Windows Media Center AutoPlay handler entries to the registry.
Download w7-ehome-autoplay.zip, and save to Desktop. Unzip and run the enclosed REG file.
Windows Media Center is now added to the AutoPlay dialog!
