Windows 10预装了大量应用程序。这些应用程序中的大多数对大多数用户来说都是无用的，并且占用了 C 盘上不必要的空间，您将来需要安装这些空间来安装升级和安装您想要的程序。您可以安全地删除临时文件、不需要的文件夹、缓存等。

删除^(Remove)不需要的Windows程序、功能和垃圾

通过删除预安装的Windows 应用商店^{(Windows Store)}应用和不需要的程序，释放Windows 10中的更多磁盘空间。这篇文章还解释了如何通过使用以下方法删除不需要的Windows功能来提高速度：

1. 卸载预装的 Windows 应用程序
2. 使用存储选项^{(Use Storage Option)}释放磁盘空间^{(Disk Space)}
3. 完全清空临时文件夹
4. 删除不需要的 Windows^{(Remove Unwanted Windows)}功能和组件
5. 删除 MSOCache。

让我们来看看它们。

1]卸载预装的Windows应用程序^{(Uninstall Preinstalled Windows Apps)}

有很多预装的Windows 应用程序^{(Windows Apps)}对我们大多数人来说毫无用处。您可以随时从“设置”应用^{(the Settings app)}中删除它们。

1. 单击开始菜单将其打开
2. 单击^(Click)PC 设置^{(PC Settings)}以打开“设置”^(Settings)窗口
3. 在设置窗口中，单击系统
4. 点击^(Click)应用^(Apps)和功能^(Features)；_ 右侧的窗口将填充您可以删除的预装Windows 10应用程序列表^{(Windows 10)}
5. 单击^(Click)一个应用程序以查看选项Move和Uninstall。
6. 单击^(Click)卸载^(Uninstall)以删除应用程序
7. 删除所有应用程序后，关闭“设置”^(Settings)窗口。

注意：^{(NOTE: )}卸载功能^(Uninstall)并非适用于所有Windows 10应用程序。Windows认为其中一些对您来说是必不可少的，因此您不会在它们旁边看到“卸载”按钮。^(Uninstall)

2]使用存储选项^{(Use Storage Option)}释放磁盘空间^{(Disk Space)}

Storage Sense有点类似于我们之前在关于Windows 10 中的垃圾文件^{(Junk files in Windows 10)}的帖子中讨论的磁盘清理工具^{(Disk Cleanup tool )}。

1. 打开设置应用
2. 点击系统
3. 单击左侧面板中的存储
4. 在右侧面板中，单击C Drive以查看所有占用驱动器空间的内容
5. 分析后，您将获得有关C 盘^{(C Drive)}占用空间的详细信息
6. 单击^(Click)一个项目以获取更多选项：如果单击应用程序^(Apps)，您将获得如上一节所述的删除应用程序对话框；^{(Remove Apps)}如果您单击临时文件，您将看到一个窗口，其中包含删除临时文件的选项
7. 根据可用选项自行决定清理此 PC
8. 关闭设置窗口。

3]完全清空临时文件夹

清空包含临时文件的文件夹。虽然磁盘清理^{(Disk Cleanup)}会删除临时文件，但它会忽略最近7 天内创建的最新临时文件^{(temporary files created in the last 7 days)}。要删除所有临时文件，

1. 按 WinKey+R
2. 键入 cmd 并按 Enter
3. 在命令行窗口中，键入DEL %temp%\*.*
4. 有些文件可能正在使用中，不会被删除，但删除其他临时文件是完全安全的
5. 键入^(Type)Exit 以关闭命令行窗口。

4]删除不需要的Windows^{(Remove Unwanted Windows)}功能和组件

您可以删除不需要的 Windows 功能^{(remove unwanted Windows features)}以加速Windows 10。例如，如果您不需要将文档转换为XPS ，您可以从^(XPS)Programs and Features中删除该功能。

1. 在控制面板^{(Control Panel)}中打开程序^(Programs)和功能^(Features)，然后单击打开或关闭Windows 功能^{(Turn Windows Features)}
2. 检查所有已安装的功能并取消选中您要删除的功能
3. 单击确定以删除功能

注意：^(Note:)如果您觉得需要任何已删除的功能，您可以使用相同的方法重新安装这些功能。

5]删除MSOCache

如果您使用的是MS Office桌面应用程序，您将在根驱动器中看到一个名为MSOcache的文件夹。^(MSOcache)根驱动器是Windows 10操作系统工作的地方——它通常是几乎所有计算机上的 C 驱动器，除非您配置了双启动并将Windows 10安装在单独的驱动器上。

MSOCache只不过是与MS Office相关的文件缓存。删除它不会影响您的计算机。您可以毫无顾虑地删除它。通常^(Often)，MSOCache文件夹不会使用文件夹中的所有文件。当您处理MS Office^{(MS Office)}应用程序时，它会不断增加大小。删除它也不会减慢您的MS Office。要删除文件夹，请右键单击它并从上下文菜单中选择删除。^(Delete)您也可以选择它并按键盘上的DEL键。

注意^(NOTE)：如果您删除MSOCache，您将无法修复Microsoft Office程序。如果您觉得有必要，您甚至可能会发现很难卸载它们。

此外，您可以删除不需要和过时的Windows 注册表^{(Windows Registry)}项以获得空间。有许多第三方免费注册表和垃圾清理^{(Free Registry and Junk Cleaners)}器可用。如果您有兴趣释放更多空间，您可能想阅读如何在 Windows 中增加磁盘空间。

Remove unwanted Windows programs, apps, folders, features

Windows 10 comes with plenty of preinstalled apps. Most of these apps are useless for most users and take up unnecessary space on the C drive which you need to install upgrades in future and to install programs that you wish. There are temporary files, unwanted folders, caches, etc, that you can remove safely.

Remove unwanted Windows programs, features & junk

Free up more disk space in Windows 10 by removing pre-installed Windows Store apps and unwanted programs. This post also explains how to gain more speed by removing unwanted Windows features, by using these methods:

1. Uninstall Preinstalled Windows Apps
2. Use Storage Option to Free up Disk Space
3. Empty the Temp Folder completely
4. Remove Unwanted Windows features & components
5. Delete MSOCache.

Let us take a look at them.

1] Uninstall Preinstalled Windows Apps

There are plenty of preinstalled Windows Apps that are of no use to most of us. You can always remove them from the Settings app.

1. Click on Start Menu to open it
2. Click on PC Settings to open the Settings window
3. In the Settings Window, click on System
4. Click on Apps and Features; the window towards the right will be populated with the list of preinstalled Windows 10 apps that you can remove
5. Click on an app to see the options Move and Uninstall.
6. Click on Uninstall to remove the application
7. After removing all the apps, close the Settings window.

NOTE: The Uninstall feature is not available for all Windows 10 apps. Some of them, Windows thinks, are essential to you, and hence you will not see the Uninstall button next to them.

2] Use Storage Option to Free up Disk Space

Storage Sense is somewhat similar to the Disk Cleanup tool we discussed earlier in our post about Junk files in Windows 10.

1. Open Settings app
2. Click on System
3. Click on Storage in Left panel
4. In the right panel, click on C Drive to see what all is taking up space on the drive
5. After an analysis, you get details of what is taking up space on C Drive
6. Click on an item to get more options: If you click on Apps, you will get the Remove Apps dialog as explained in the above section; if you click on temporary files, you will get a window that has options to delete to temporary files
7. Clean up This PC using your discretion based on the options available
8. Close the Settings window.

3] Empty the Temp Folder completely

Empty the folder containing the Temporary files. While Disk Cleanup removes temporary files, it omits the most recent temporary files created in the last 7 days. To delete all the temporary files,

1. Press WinKey+R
2. Type cmd and press Enter
3. In the command line window, type DEL %temp%\*.*
4. Some files won’t be deleted as they may be in use, but it is perfectly safe to delete other temporary files
5. Type Exit to close the command line window.

4] Remove Unwanted Windows features & components

You can remove unwanted Windows features to speed up Windows 10. For example, if you do not have a need to convert documents into XPS, you can remove the feature from Programs and Features.

1. Open the Programs and Features in Control Panel and click on Turn Windows Features On or Off
2. Check out what all features are installed and uncheck the features that you wish to remove
3. Click on OK to remove the features

Note: You can reinstall the features using the same method if you feel the need for any of the removed features.

5] Delete MSOCache

If you are using MS Office desktop applications, you will see a folder called MSOcache in the root drive. The root drive is from where the Windows 10 OS works – it is often the C drive on almost all computers unless you have configured a dual boot and installed Windows 10 on a separate drive.

MSOCache is nothing but a cache of files related to MS Office. Removing it will not affect your computer. You can remove it without any worries. Often, the MSOCache folder does not use all the files in the folder. It keeps on increasing the size as you work on MS Office applications. Deleting it won’t slow down your MS Office either. To remove the folder, right-click on it and select Delete from the context menu. You can also select it and press the DEL key on the keyboard.

NOTE: If you delete MSOCache, you will not be able to repair Microsoft Office programs. You may even find it difficult to uninstall them, should you feel the need to do so.

In addition, you can remove unwanted and obsolete Windows Registry entries to gain space. There are many third party Free Registry and Junk Cleaners available. If you are interested in freeing up more space, you may want to read how to increase Disk Space in Windows.
