如果您在从Windows 10访问文档或访问网络共享^{(Network Share)}上的文件时遇到延迟，那么这篇文章将能够为您提供帮助。在这篇文章中，我们将确定此问题的潜在原因，并提供您可以尝试帮助您缓解问题的解决方案和解决方法。

让我们看一下您可能会遇到此问题的典型场景。

您将Windows 10计算机升级到嵌套版本。升级完成后，您将访问包含数千个文件和文件夹的网络共享，并打开位于该共享上的文档。在这两个操作期间，您都会遇到严重的延迟。但是，如果您uninstall/rollback the Windows 10版本，则可以毫无延迟地访问网络共享。

此问题会影响Windows 10缓存大型目录^{(cache large directories)}的能力。

如果您在从Windows 10^{(Windows 10)}计算机访问网络共享上的文档时遇到延迟，您可以尝试推荐的解决方案或下面描述的解决方法来解决问题。

要解决此问题，请确保您已安装所有最新的Windows 更新^{(Windows Updates)}并升级到最新的稳定 Windows 10 版本。

如果由于某种原因无法将计算机升级到更高版本的Windows 10 ，您可以通过配置以下注册表子项来解决此问题：^{(work around the issue)}

DirectoryCacheLifetime: REG_DWORD: 0

由于这是注册表操作，建议您备份注册表^{(back up the registry)} 或 创建系统还原点。

采取必要的预防措施后，您可以进行以下操作：

按 Windows 键 + R. 在“运行”对话框中，键入regedit并按 Enter打开注册表编辑器^{(open Registry Editor)}。

导航或跳转到下面的注册表项路径：

HKLM\System\CurrentControlSet\Services\LanmanWorkstation\Parameters

标识DirectoryCacheLifetime条目。

如果该条目不存在，请右键单击右侧窗格中的空白区域，然后选择New > DWORD (32-bit) Value。然后将值名称重命名为DirectoryCacheLifetime 并按 Enter。

• 现在，双击条目以编辑其属性。
• 在数值数据^{(Value data)}框中键入0 ，然后⁽⁰⁾按 Enter^(Enter)以保存更改。

您现在可以退出注册表编辑器^{(Registry Editor)}并重新启动您的 PC。现在应该解决网络共享延迟问题。

That’s it!

If you are fаcing delays when accessing documents or accessing files on a Network Ѕhare from Windows 10, then this post will be able to help you. In this post, we will, identify the potential caυse of thіs issue, as well as provide both the sоlution and workaround you can try to help you mitigate thе issuе.

Let’s take a look at a typical scenario where you can encounter this issue.

You upgrade a Windows 10 computer to the nest version. After the upgrade finishes, you access a network share that contains thousands of files and folders, and you open a document that is located on that share.

Slow access to Network drive from Windows 10

If you’re faced with delays when accessing documents on a network share from a Windows 10 computer, you can try the recommended solution or the workaround described below to resolve the issue.

To resolve this issue, make sure that you have installed all the latest Windows Updates and upgraded to the latest stable Windows 10 version.

If you cannot upgrade the computer to a later version of Windows 10 for some reason, you can work around the issue by configuring the following registry subkey:

DirectoryCacheLifetime: REG_DWORD: 0

Since this is a registry operation, it is recommended that you back up the registry or create a system restore point.

Once you have taken the necessary precautionary measures, you can proceed as follows:

Press Windows key + R. In the Run dialog box, type regedit and press Enter to open Registry Editor.

Navigate or jump to the registry key path below:

HKLM\System\CurrentControlSet\Services\LanmanWorkstation\Parameters

Identify the DirectoryCacheLifetime entry.

If the entry is not present, right-click on the blank space on the right pane and then select New > DWORD (32-bit) Value. Then rename the value name as DirectoryCacheLifetime and hit Enter.

• Now, double-click on the entry to edit its properties.
• Type 0 in the Value data box and hit Enter to save the change.

You can now exit Registry Editor and restart your PC. The network share delays issue should be resolved now.

That’s it!
