每次向终端消费者推出Windows 功能更新^{(Windows Feature Update)}时，都会有很多人抱怨存储空间不足、无法下载更新、更新体验缓慢等问题。问题是他们中的许多人在计算机上没有足够的存储空间。预留存储^{(Reserved Storage)}将自动出现在预装Windows或全新安装的设备上。^(Windows)在本指南中，我们将向您展示如何在 Windows 11/10中启用或禁用保留存储。^{(Reserved Storage)}

Windows 11/10中启用或禁用保留存储

微软^(Microsoft)希望确保所有更新都不会因为存储空间不足而卡住。更新^(Update)进程应该有足够的空间，以便它可以下载、解压缩然后应用更新。保留存储^{(Reserved Storage)}的大小通常约为 7 GB。它为更新、临时文件、应用程序、系统缓存等提供了足够的空间。根据Microsoft的说法，^(Microsoft)预留存储^{(Reserved Storage)}速度的大小会随着时间和您使用设备的方式而变化。

也就是说，默认情况下，该功能在预装了2019 年 5 月^{(May 2019)} 更新^(Update)的设备上启用，或者在执行操作系统的全新安装之后启用。要检查您是否有此功能，请按照以下步骤操作：

1. 打开设置>系统>存储
2. 单击 显示更多类别^{(Show more categories)} 链接。
3. 单击系统和保留项。

如果您没有找到列出的预留^(Reserved) 存储^(Storage)，可能是因为设备在硬盘上的空间有限，或者如果您有此功能，它不是全新或新安装的，并且您不想使用它，这里是如何禁用它。此外，在预装了Windows 10、v1903 和全新安装的新 PC 上，预留^(Reserved)存储将自动启用。从以前版本的Windows 10^{(Windows 10)}更新时不会启用它。

使用注册表^(Registry)启用或禁用保留存储

这是您应该了解的有关Reserved Storage的内容。如果禁用它，您可能无法重新启用它。我在我现有的电脑上试了一下，还是不行。

因此，既然您已选择禁用Reserved Storage，您需要使用Registry Editor。

通过在RUN提示符下键入regedit并按^(regedit)Enter键^(Enter)打开注册表编辑器。

导航：

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\ReserveManager

双击 DWORD ShippedWithReserves并将值设置为1。

重新启动^(Reboot)计算机，存储存储^{(Storage Storage)}将不再可用。

要撤消更改，只需撤消所做的更改。^{(To reverse the changes, simply undo the changes you made.)}

我希望微软^(Microsoft)将此作为用户可以按需启用的功能推出。

阅读^(Read)：DISM 命令禁用或启用保留存储^{(DISM commands to Disable or Enable Reserved Storage)}。

如何减少预留存储大小

如果你想减少Reserved Storage的空间，目前有两种方法：

1. 导航^(Navigate)到Settings > Apps > Apps和功能 >管理^(Manage)可选功能。卸载您不使用的可选功能。^{(Uninstall optional features)}
2. 转到Settings > Time和Language > Language。卸载^{(Uninstall languages)}您不使用的语言及其附加组件。

^(Reserved)应用程序和系统进程也使用保留的存储空间来创建临时文件。当预留^(Reserved)存储空间填满时，Windows 10 会自动删除不需要的临时文件。

这是一个有用的功能，最好不要禁用它。但是，如果您的存储空间不足，您可以选择这样做。

How to enable or disable Reserved Storage in Windows 11/10

Every time a Windows Fеatυrе Update rolls out to end consumers, many complain aboυt low storage space, not able to download the updates, slow update experience, and so on. Τhe problem is that many of them dont have enough storage spaсe avаilable on the computer. Reserved Storage will be present automatically on devices that come with Windows pre-installed or those where it was clean installed. In this guide, we will show you how you can enable or disable Reserved Storage in Windows 11/10.

Enable or Disable Reserved Storage in Windows 11/10

Microsoft wants to make sure none of the updates gets stuck because of low storage space. The Update process should have enough space so it can download, extract, and then apply the update. The size of the Reserved Storage is usually around 7 GB. It gives enough space for the update, temporary files, apps, system caches, and so on. According to Microsoft, the size of the Reserved Storage pace will vary over time & how you use your device.

That said, the feature is enabled by default on devices that come pre-installed with the May 2019 Update, or after performing a clean installation of the operating system. To check if you have this feature, follow the steps as below:

1. Open Settings > System > Storage
2. Click the Show more categories link.
3. Click the System & reserved item.

If you do not find Reserved Storage listed, it’s probably because the device has limited space on the hard disk or it is not a fresh or new install if you have this feature, and you don’t want to use it, here is how to disable it. Also, Reserved storage will be enabled automatically on new PCs with Windows 10, v1903 pre-installed, and for clean installs. It will not be enabled when updating from a previous version of Windows 10.

Enable or Disable Reserved Storage using Registry

Here is the thing you should know about Reserved Storage. If you disable it, the chances are that you cannot re-enable it. I tried it on my existing computer, and it did not work.

So, now that you have chosen to disable the Reserved Storage, you need to use the Registry Editor.

Open the Registry Editor by typing regedit in the RUN prompt and hitting the Enter key.

Navigate to:

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\ReserveManager

Double click on the DWORD ShippedWithReserves and set the value to 1.

Reboot the computer, and the Storage Storage will not be available anymore.

To reverse the changes, simply undo the changes you made.

I hope Microsoft rolls out this as a feature in which the user can enable it on demand.

How to reduce Reserved Storage size

If you wish to reduce the space of Reserved Storage, there are two ways as of now:

1. Navigate to Settings > Apps > Apps & features > Manage optional features. Uninstall optional features that you are not using.
2. Go to Settings > Time & Language > Language. Uninstall languages and their add-ons which you are not using.

Reserved storage is also used by apps and system processes to create temporary files. When the Reserved storage space fills up, Windows 10 will automatically delete the unneeded temporary files.

It is a useful feature, and it’s best not to disable it. However, if you are running low on storage space, you may choose to do so.
