如果您的Internet^(Internet)受限或Internet速度较慢，您可能需要找到解决方法来下载应用程序或更新。一种这样的解决方法是从网络中的另一台计算机下载更新。Windows 更新传递优化可让您做到这一点。

虽然您可以使用 Settings、REGEDIT 或 GPEDIT^{(REGEDIT or GPEDIT)}禁用 WUDO ，但您可能希望稍微更改其设置以使其根据您的需要工作。一种这样的设置是Delivery Optimization Max Cache Size。有两个策略，  Max Cache Size 和 Absolute Max Cache Size， 我们将把它们更改为 Change Delivery Optimization Max Cache Size for Updates in Windows 11/10。

更改Windows 更新^{(Windows Updates)}的传递优化最大缓存大小^{(Delivery Optimization Max Cache Size)}

在继续之前，让我们看看这些政策是什么。

• 最大缓存大小 ^{(Max Cache Size )}用于指定传递优化^{(Delivery Optimization)}缓存可以使用的总空间百分比。因此，当缓存大小达到阈值时，计算机将自动删除存储的缓存并开始创建新缓存。
• ^{(Absolute Max Cache Size, )}另一方面，绝对最大缓存大小 允许您以千兆字节^(Gigabytes)为单位设置最大缓存大小。这与 Max Cache Size 不同， ^{(Max Cache Size, )}您可以在其中指定用于缓存的总可用存储空间的百分比，因为在这里，您要设置一个特定的值。

您一次只能配置一个策略。如果您配置Absolute Max Cache Size，它将覆盖Max Cache Size策略。

这是我们要更改Windows 10中更新^(Updates)的交付优化最大缓存大小^{(Delivery Optimization Max Cache Size)}的两种方法。

1. 通过组策略编辑
2. 通过注册表编辑器

让我们详细谈谈它们。

1]由组策略编辑器

由于它们都是策略，因此组策略编辑器^{(Group Policy Editor)}可能是更改其设置的最简单方法。

为此， 通过 Win + R, 组策略编辑器 ^{(Group Policy Editor )}，键入“ gpedit.msc”，然后按 Enter。

导航到以下位置。

Computer Configuration > Administrative Templates > Windows Components > Delivery Optimization

现在， 根据您要配置的策略，查找最大缓存大小（百分比） ^{(Max Cache Size (percentage) )}或 绝对最大缓存大小（以 GB 为单位） 。^{(Absolute Max Cache Size ( in GB), )}

双击它，选择 启用^{(Enabled )}并更改大小。对于 Max Cache Size (percentage) 设置 1-100 之间的任何值，对于 Absolute Max Cache Size (in GB)设置任何以 GB 为单位的值。

配置这两个策略中的任何一个后，您可以关闭组策略编辑器^{(Group Policy Editor)}，您的传递优化^{(Delivery Optimization)}将相应地工作。

2]通过注册表编辑器

Window 10 Home没有组策略编辑器，因此，您可以在^{(Group Policy Editor)}注册表编辑器 ^{(Registry Editor. )}的帮助下更改策略 。因此， 通过在“开始”菜单^{(Start Menu)}中搜索并导航到以下位置来启动注册表编辑器 。^{(Registry Editor )}

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\DeliveryOptimization

如果没有 DeliveryOptimization 键，右键单击Windows，选择 New > Key，并将其命名为“DeliveryOptimization”。然后右键单击DeliveryOptimization 并选择 New > DWORD (32-bit) Value.

现在，要配置最大缓存大小（百分比）， ^{(Max Cache Size (percentage), )}请将值命名为DOMaxCacheSize，如果要设置绝对最大缓存大小（以 GB 为单位）^{(Absolute Max Cache Size (in GB))}， 请将值命名为DOAbsoluteMaxCacheSize。

双击^{(Double-click)}新创建的值，选择 Decimal 作为基数并相应地设置Value 数据^{(Value data )}。对于 Max Cache Size (percentage) 设置 1-100 之间的任何值，对于 Absolute Max Cache Size (in GB)设置任何以 GB 为单位的值。

希望^(Hopefully)现在您知道如何更改传递优化最大缓存大小^{(Delivery Optimization Max Cache Size)}。

Change Delivery Optimization Max Cache Size for Windows Updates

If you have limited Internet or if your Internet speed is slow, you may need to find a workaround to downlоad an application or update. One ѕuch workaround is downloading the update from another computer in your network. Windows Update Delivery Optimization lets you do that.

While you can disable WUDO using Settings, REGEDIT or GPEDIT, you may want to, instead, alter its settings a bit to make it work according to your needs. One such setting is Delivery Optimization Max Cache Size. There are two policies, Max Cache Size and Absolute Max Cache Size, and we are going to alter them to Change Delivery Optimization Max Cache Size for Updates in Windows 11/10.

Change Delivery Optimization Max Cache Size for Windows Updates

Before moving any further, let’s see what these policies are.

• Max Cache Size is used to specify the percentage of total space Delivery Optimization cache can use. So, when the cache size reaches the threshold value the computer will automatically delete the stored cache and started creating new ones.
• Absolute Max Cache Size, on the other hand, allows you to set a maximum cache size in Gigabytes. This is different from Max Cache Size, where you specify the percentage of your total available storage for cache, as here, you are setting a specific value.

You can only configure one policy at a time. If you configure the Absolute Max Cache Size, it will override the Max Cache Size policy.

These are two ways we are going to Change Delivery Optimization Max Cache Size for Updates in Windows 10.

1. By Group Policy Editor
2. By Registry Editor

Let us talk about them in detail.

1] By Group Policy Editor

Since both of them are policies, Group Policy Editor is probably the easiest way to alter their settings.

To do this, launch Group Policy Editor by Win + R, type “gpedit.msc”, and hit Enter.

Navigate to the following location.

Computer Configuration > Administrative Templates > Windows Components > Delivery Optimization

Now, look for Max Cache Size (percentage) or Absolute Max Cache Size ( in GB), depending on the policy you want to configure.

Double-click on it, select Enabled and change the size. For Max Cache Size (percentage) set any value between 1-100 and for Absolute Max Cache Size (in GB) set any value in GBs.

After configuring any of the two policies, you can close the Group Policy Editor and your Delivery Optimization will work accordingly.

2] By Registry Editor

Window 10 Home doesn’t have Group Policy Editor, so, you can alter the policy with the help of Registry Editor. So, launch Registry Editor by searching it out of the Start Menu and navigate to the following location.

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\DeliveryOptimization

If there is no DeliveryOptimization key, right-click on Windows, select New > Key, and name it “DeliveryOptimization”. Then right-click on DeliveryOptimization and select New > DWORD (32-bit) Value.

Now, to configure Max Cache Size (percentage), name the value DOMaxCacheSize, and if you want to set Absolute Max Cache Size (in GB), name the value DOAbsoluteMaxCacheSize.

Double-click on the newly created value, select Decimal as the base and set the Value data accordingly. For Max Cache Size (percentage) set any value between 1-100 and for Absolute Max Cache Size (in GB) set any value in GBs.

Hopefully, now you know how to Change Delivery Optimization Max Cache Size.
