Change which programs Windows uses by default
A default program is the program that Windows uses when you open a
particular type of file, such as a music file, an image, or a webpage. For
example, if you have more than one web browser installed on your computer,
you can choose one of them to be the default browser.
Click to open Default Programs.
In Default Programs, you can:
Set your default programs. Use this option to choose which programs you
want Windows to use by default. If you want to use your media player to
open all media files, use this option.
The options you set here only apply to your user account. Your choices
won't affect other user accounts on the computer. To change program access
for all users on this computer, see Change default programs using Set
Program Access and Computer Defaults.
Associate a file type or protocol with a program. Use this option to
fine-tune default programs based on the file type or protocol. For
example, you can have all .jpg image files open using a specific program,
and .bmp image files open using a different program.
Change AutoPlay settings. You can also change which programs to use to
start different kinds of media, such as music CDs or DVDs that contain
photos. For more information, see AutoPlay: frequently asked questions.
Set default programs for this computer. Set Program Access and Computer
Defaults is a tool to set default programs for activities such as browsing
the web and sending e-mail for everyone who uses the computer. For more
information, see Change default programs using Set Program Access and
