我们中的许多人更喜欢使用相同的程序来打开某些类型的文件。例如，您可能喜欢使用Photo Gallery打开图片，使用Windows Media Player打开音乐和视频(music and videos)。或者您可能拥有您更喜欢的第三方软件。幸运的是，Windows 7和 Windows 8.1 都可以让您轻松设置自己的首选项。这是如何做：
在哪里可以找到设置默认程序面板(Set Default Programs Panel)
为文件类型和协议设置默认程序是从名为Set Default Programs的窗口执行的。
在Windows 7中，您可以通过在开始菜单(Start Menu)搜索框中键入“默认”来访问它。("default")
在 Windows 8.1 中，打开搜索(Search)超级按钮并键入"default"。如果您在“开始(Start)”屏幕上，您只需开始输入“默认”("default")，搜索(Search)就会自动打开。
然后，从搜索结果列表中，单击或点击(click or tap) 默认程序(Default Programs)。
在Windows 7和Windows 8.1中，您可以转至控制面板(Control Panel)，单击或点击程序(Programs)，然后单击默认程序(Default Programs)。
现在您在“默认程序(Default Programs)”窗口中，单击或点击“设置您的默认程序”("Set your default programs")。
您应该记住的一件事是，您在“设置默认程序(Set Default Programs)”中所做的更改仅适用于您的用户帐户。其他用户的默认程序保持不变。
如何在Windows 7和Windows 8.1中设置(Windows 8.1)默认程序(Default Programs)
打开“设置默认程序(Set Default Programs)”窗口后，您将看到可用于打开各种文件的所有可用程序的列表。这里的插图来自我的电脑。根据您安装的内容，您的外观会有所不同。
你所看到的就是你得到的; 您无法将更多程序添加到此列表中。如您所见，Windows 7和Windows 8.1中的窗口看起来几乎相同。这是窗口在Windows 7中的外观。
如您所见，在Windows 8.1中，您有更长的选择列表，因为它还显示来自Windows 应用商店(Windows Store)的现代应用程序。
对于每个列出的程序，您可以选择让它处理它能够处理的所有文件类型，或者您可以将其设置为仅处理某些文件类型并将其他文件类型分配给另一个程序。让我们看看这是如何做到的。
在这里，在Windows 7中，我选择了Sony的(Sony)Reader for PC程序，我只看到了一些关于该程序的信息，并提供了一个选择，让它打开它可以打开的所有文件，或者选择它将处理哪些文件和。
那么，哇，PC 阅读器(Reader for PC)将处理哪些类型的文件？告诉它继续打开所有东西而不首先找出它的能力并不是一个好主意。单击(Click)或点击
“为此程序选择默认值”("Choose defaults for this program")。
PC 版阅读器(Reader for PC)设置为打开两种文件，.acsm（这是一种受DRM保护的电子书形式，供公共图书馆使用，允许电子书检出(e-book checkout)等）和.epub（一种非常流行的电子书书格式）。在这种情况下，我可以使用Reader for PC打开这两种文件，所以我没有更改设置。
在 Windows 8.1 中，我选择了Paint，它可以通过更多方式进行配置。它带有 3 个可能的 14 个默认设置。（作为记录，Paint在Windows 7中的设置方式相同，但我使用另一个图形程序来处理图像，并且不想选择Paint作为默认值）。
让我们看看有哪些选择：
由于我还没有在Windows 8.1中安装另一个图形编辑程序，因此我可以使用Paint打开常见的图形格式文件，因此我选择了.bmp,.gif,.jpeg,.jpg和.png以及它的现有的默认值。
选择所需内容后单击或点击保存(Save)，然后您就完成了。
结论
在Windows 7和 Windows 8.1 中，选择哪些程序打开哪些文件非常容易，尽管您可以为其设置默认值的程序列表几乎可以肯定不是包罗万象。不过，花时间浏览列表可以让您的事情变得更轻松，并让您确保您的文件可以使用您喜欢的程序打开。
How to Set Your Default Programs in Windows 7 and Windows 8.1
Many of us prefer to usе the same program to open certаin types of files. Fоr example, уou may like to use Photo Gallery to open pictures and Windows Media Player to open music and videos. Or you may have third-party software that you like better. Fortunately, both Windows 7 and Windows 8.1 make it very easy to set your own preferences. Here's how:
Where to Find the Set Default Programs Panel
Setting the default programs for file types and protocols, is performed from a window named Set Default Programs.
In Windows 7, you can reach it by typing "default" into the Start Menu search box.
In Windows 8.1, open the Search charm and type "default". If you are on the Start screen, you can simply begin typing "default" and the Search will automatically open.
Then, from the search results list, click or tap Default Programs.
In both Windows 7 and Windows 8.1, you can go to the Control Panel, click or tap Programs, and then Default Programs.
Now that you are in the Default Programs window, click or tap "Set your default programs".
One thing that you should keep in mind is that the changes you make in Set Default Programs will apply only to your user account. The default programs for other users remained unchanged.
How to Set Your Default Programs in Windows 7 & Windows 8.1
Once you have opened the Set Default Programs window, you'll see a list of all the available programs that you can use to open various kinds of files. The illustrations here are from my computers. Yours will look different depending on what you have installed.
What you see is what you get; you can't add more programs to this list. The windows look pretty much the same in Windows 7 and Windows 8.1, as you can see. Here is how the window looks in Windows 7.
As you can see, in Windows 8.1 you have a longer list of choices because it displays also modern apps from the Windows Store.
With each listed program, you can choose to have it handle all the file types it's capable of handling, or you can set it to deal with only certain file types and assign the others to another program. Let's see how this is done.
Here, in Windows 7, I have chosen the Reader for PC program from Sony, and I'm shown just a little information about the program and offered a choice to have it open all the files it can, or choose which files it will deal with.
Well, whoa, what kinds of files will the Reader for PC deal with? Not a good idea to tell it to just go ahead and open everything without finding out what it's capable of, first. Click or tap "Choose defaults for this program".
Reader for PC is set up to open two kinds of files, .acsm(which is a DRM protected form of e-book used by public libraries that allow e-book checkout, among other things) and .epub (a very popular e-book format). In this case I am OK with Reader for PC opening both kinds of files, so I didn't change the settings.
In Windows 8.1, I've chosen Paint, which can be configured in a lot more ways. It comes with 3 of the possible 14 defaults set. (For the record, Paint is set the same way in Windows 7, but I use another graphics program for images and did not want to choose Paint as the default).
Let's see what the choices are:
Since I haven't installed another graphics-editing program in Windows 8.1 yet, I am fine with Paint opening the common graphics format files, so I've selected .bmp,.gif,.jpeg,.jpg and .png, alongside its existing defaults.
Click or tap Save after choosing what you want, and you're done.
Conclusion
In both Windows 7 and Windows 8.1 it's very easy to choose which programs open which files, although the list of programs for which you can set defaults is almost certain not to be all-inclusive. Still, taking the time to go through the list can make things easier for you, and let you make sure that your files open with the programs you prefer.
