edge无法加载flash
In the Windows 10 October 2018 Update, Edge received a performance boost that lets it pre-launch processes and preload the Start and New Tabs during Windows startup. If you don’t use Edge, though, these optimizations are wasting resource and slowing startup. With a quick Registry hack or Group Policy setting, you can disable it.
在Windows 10 October 2018 Update中，Edge获得了性能提升，可以在Windows启动期间预启动进程并预加载``开始''和``新选项卡''。 但是，如果您不使用Edge，这些优化将浪费资源并减慢启动速度。 通过快速的注册表黑客或组策略设置，您可以将其禁用。

If you have Windows Home edition, you will have to use Registry Editor to make these changes. You can also do it this way if you have Windows Pro or Enterprise, but feel more comfortable working in the Registry. (If you have Pro or Enterprise, though, we recommend using the easier Local Group Policy Editor, as described later in the article.)
如果您使用Windows Home Edition，则必须使用注册表编辑器进行这些更改。 如果您使用的是Windows Pro或Enterprise，但也可以通过这种方式进行操作，但是在注册表中使用它会感到更加自在。 (但是，如果您具有Pro或Enterprise，我们建议使用更简单的“本地组策略编辑器”，如本文稍后所述。)
Standard warning: Registry Editor is a powerful tool and misusing it can render your system unstable or even inoperable. This is a pretty simple hack, and as long as you stick to the instructions, you shouldn’t have any problems. That said, if you’ve never worked with it before, consider reading about how to use the Registry Editor before you get started. And definitely back up the Registry (and your computer!) before making changes.
标准警告：注册表编辑器是一个功能强大的工具，滥用它会使您的系统不稳定甚至无法运行。 这是一个非常简单的技巧，只要您按照说明进行操作，就不会有任何问题。 也就是说，如果您以前从未使用过它，请在开始之前考虑阅读有关如何使用注册表编辑器的信息。 并在进行更改之前一定要备份注册表(和您的计算机！)。
To do this, you’re going to have to make two separate edits in the Registry: one to prevent pre-launching of processes and another to prevent preloading of the start and new tab pages. We’ll take them one at a time.
为此，您将不得不在注册表中进行两项单独的编辑：一项是防止进程的预启动，另一项是防止预加载开始页和新选项卡页。 我们一次带他们一个。
(Prevent Pre-Launching of Microsoft Edge Processes)
To get started, open the Registry Editor by hitting Start and typing “regedit.” Press Enter to open Registry Editor and then permit it to make changes to your PC.
首先，点击开始并键入“ regedit”，打开注册表编辑器。 按Enter打开注册表编辑器，然后允许它对您的PC进行更改。
In the Registry Editor, use the left sidebar to navigate to the following key (or copy and paste it into the Registry Editor address bar):
在注册表编辑器中，使用左侧边栏导航至以下键(或将其复制并粘贴到注册表编辑器地址栏中)：
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\MicrosoftEdge\Main
Now, right-click on the main key and choose New > DWORD (32-bit) Value. Name the new value AllowPrelaunch.
现在，右键单击main键，然后选择“新建”>“ DWORD(32位)值”。 将新值AllowPrelaunch 。
Now, you’re going to modify that value. Double-click the new AllowPrelaunch value, set the value to 0 in the “Value data” box, and then click “OK.”
现在，您将修改该值。 双击新的AllowPrelaunch值，在“数值数据”框中将其值设置为0，然后单击“确定”。
You can change back to the default behavior later by going back and changing that AllowPrelaunch value to 1.
您可以稍后通过将AllowPrelaunch值更改为1来更改回默认行为。
(Prevent Preloading of Start and New Tabs)
In the Registry Editor, use the left sidebar to navigate to the following key (or copy and paste it into the Registry Editor address bar):
在注册表编辑器中，使用左侧边栏导航至以下键(或将其复制并粘贴到注册表编辑器地址栏中)：
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\MicrosoftEdge
Right-click the MicrosoftEdge folder and choose New > Key. Name the new key TabPreloader.
右键单击MicrosoftEdge文件夹，然后选择“新建”>“密钥”。 将新密钥TabPreloader 。
Now, right-click on the TabPreloader key and choose New > DWORD (32-bit) Value. Name the new value AllowTabPreloading.
现在，右键单击TabPreloader键，然后选择“新建”>“ DWORD(32位)值”。 将新值AllowTabPreloading 。
Now, you’re going to modify that value. Double-click the new AllowTabPreloading value, set the value to 0 in the “Value data” box, and then click “OK.”
现在，您将修改该值。 双击新的AllowTabPreloading值，在“数值数据”框中将其值设置为0，然后单击“确定”。
You can now exit Registry Editor. For the changes to take effect, you’ll need to restart your computer. To change things back to the default behavior, you can go back and set that AllowTabPreloading value to 1.
您现在可以退出注册表编辑器。 为了使更改生效，您需要重新启动计算机。 要将其更改为默认行为，可以返回并将该AllowTabPreloading值设置为1。
(Download Our One-Click Registry Hack)
If you don’t feel like diving into the Registry yourself, we’ve created some Registry hacks you can use. Just download and extract the following ZIP file:
如果您不想自己进入注册表，我们已经创建了一些可以使用的注册表黑客。 只需下载并解压缩以下ZIP文件：
PreventPreloadingAndPre-LaunchingOfMicrosoftEdge
PreventPreloadingAndPre-LaunchingOfMicrosoftEdge
Inside you’ll find REG files for disabling pre-launching and preloading. Once extracted, double-click the file you want and accept the prompts asking whether you’re sure you want to make changes to your Registry. You’ll also find files for re-enabling both features.
在内部，您将找到REG文件以禁用预启动和预加载。 解压缩后，双击所需的文件并接受提示，询问您是否确定要对注册表进行更改。 您还将找到用于重新启用这两个功能的文件。
These hacks work by adding the AllowPrelaunch and AllowTabPreloading values to the MicrosoftEdge key we talked about in the previous section. We created them by making the changes in our own Registry and then exporting just those changes to a REG file. Running the hacks modifies the values in your Registry. And if you enjoy fiddling with the Registry, it’s worth taking the time to learn how to make your own Registry hacks.
这些黑客通过将AllowPrelaunch和AllowTabPreloading值添加到上一节中讨论的MicrosoftEdge密钥中来工作。 我们通过在我们自己的注册表中进行更改，然后将这些更改仅导出到REG文件中来创建它们。 运行hack会修改注册表中的值。 而且，如果您喜欢使用注册表，则值得花时间学习如何制作自己的注册表黑客。
(Pro and Enterprise Users: Prevent Pre-Launching and Preloading Using Group Policy)
If you’re using Windows Pro or Enterprise, the easiest way to disable pre-launching Edge and preloading of the Start and New Tab pages is by using the Local Group Policy Editor. It’s a pretty powerful tool, so if you’ve never used it before, it’s worth taking some time to learn what it can do. Also, if you’re on a company network, do everyone a favor and check with your admin first. If your work computer is part of a domain, it’s also likely that it’s part of a domain group policy that will supersede the local group policy, anyway.
如果您使用的是Windows Pro或Enterprise，则禁用“预启动Edge”和“开始”和“新选项卡”页面的预加载的最简单方法是使用“本地组策略编辑器” 。 这是一个非常强大的工具，因此，如果您以前从未使用过它，那么值得花一些时间来学习它可以做什么。 另外，如果您在公司网络中，请给所有人一个帮助，并首先与您的管理员联系。 如果您的工作计算机是域的一部分，则它也很可能是域组策略的一部分，无论如何，该组策略将取代本地组策略。
Note: To make these changes in the Local Group Policy Editor you must be running Windows 10 Pro (or Enterprise) version 1809 or later for pre-launching of Microsoft Edge processes, and version 1803 or later for preloading Start and New Tab page.
注意：要在本地组策略编辑器中进行这些更改，您必须运行Windows 10 Pro(或企业)版本1809或更高版本以预启动Microsoft Edge进程，并运行版本1803或更高版本以预加载``开始和新建选项卡''页面。
In Windows Pro or Enterprise, fire up the Local Group Policy Editor by hitting Start, typing “gpedit.msc” into the search box, and then pressing Enter.
在Windows Pro或Enterprise中，通过单击开始，在搜索框中键入“ gpedit.msc”，然后按Enter，启动本地组策略编辑器。
In the left-hand pane of the Local Group Policy Editor window, drill down to Local Computer Policy > Computer Configuration > Administrative Templates > Windows Components > Microsoft Edge. On the right, look for the “Allow Microsoft Edge pre-launch at Windows startup, when the system is idle, and each time Microsoft Edge is closed” and “Allow Microsoft Edge to start and load the Start and New Tab page at Windows startup and each time Microsoft Edge is closed” items. You’ll be double-clicking each one in turn and making the same change in each.
在“本地组策略编辑器”窗口的左侧窗格中，向下钻取到“本地计算机策略”>“计算机配置”>“管理模板”>“ Windows组件”>“ Microsoft Edge”。 在右侧，找到“在Windows启动时，系统空闲时以及每次关闭Microsoft Edge时允许Microsoft Edge预启动”和“在Windows启动时允许Microsoft Edge启动并加载“开始和新选项卡”页面”并在每次Microsoft Edge关闭时显示“项目”。 您将依次双击每个对象，并对每个对象进行相同的更改。
When you open either setting, select the “Disabled” option and then click “OK.”
当您打开任一设置时，请选择“禁用”选项，然后单击“确定”。
After disabling both options, you can exit the Local Group Policy Editor. You’ll need to restart your PC for the changes to take effect. If you want to re-enable either feature, use the editor to set the items back to “Not Configured.”
禁用这两个选项后，您可以退出本地组策略编辑器。 您需要重新启动PC才能使更改生效。 如果要重新启用任一功能，请使用编辑器将项目设置回“未配置”。
