例如，如果要将其设置为 1 小时，请输入 3600 并单击 确定 ^(OK )按钮。

右键单击 SleepingTabsBlockedForUrls > New > String value 并将其命名为 1。

然后，双击它，并输入网站URL作为值^(Value)数据。

如何使用组策略启用或禁用^{(Group Policy)}Edge中的睡眠标签^(Tabs)

需要下载 Microsoft Edge 的组策略模板^{(download the Group Policy template for Microsoft Edge)}才能使用组策略方法。

要使用组策略^{(Group Policy)}启用或禁用Edge中的睡眠^(Edge)标签^(Tabs)，请按照下列步骤操作 -

Computer Configuration > Administrative Templates > Classic Administrative Templates > Microsoft Edge - Default Settings > Sleeping Tabs settings

在您的右侧，您可以看到一个名为 Configure Sleeping Tabs的设置。双击它，选择 启用 ^(Enable )选项，然后单击 确定 ^(OK )按钮保存更改。

还有两个设置 – 为特定站点上^{(Block Sleeping Tabs on specific sites)}的睡眠标签 和 阻止睡眠标签设置后台标签不活动超时^{(Set the background tab inactivity timeout for Sleeping Tabs)}。

要选择不活动超时，双击前一个设置，选择 启用 ^(Enabled )选项，展开下拉列表，然后根据您的要求选择一个时间。

如果要禁用特定网站的 Sleeping Tabs，双击后一个设置，选择Enabled 选项，单击 Show 按钮，输入网站URL，然后单击 OK 按钮。

就这样！希望能帮助到你。

Turn on or off Sleeping Tabs in Edge using Registry or Group Policy

If you want to reduce CPU, memоry, or battery usage on your Windows 10 laptop, the Sleeping tab feature is one option you can consider. Although it is possible to enable or disable Sleeping Tabs in Edge using Edge flags, you can do the same using the Registry Editor and the Local Group Policy Editor in Windows 10.

Turn on or off Sleeping Tabs in Edge using Registry Editor

To turn on or off Sleeping Tabs in Edge using Registry Editor, follow these steps-

1. Press Win+R to open the Run prompt.
2. Type regedit and press the Enter button.
3. Click the Yes option in the UAC prompt.
4. Navigate to Microsoft in HKEY_LOCAL_MACHINE.
5. Right-click on Microsoft > New > Key.
6. Name it as Edge.
7. Right-click on Edge > New > Key.
8. Name it as Recommended.
9. Right-click on Recommended > New > DWORD (32-bit) Value.
10. Name it as SleepingTabsEnabled.
11. Double-click on it to set the Value data as 1.
12. Click the OK button.

Press Win+R, type regedit and hit the Enter button. If you find the UAC prompt, click the Yes button to open the Registry Editor on your computer. After that, navigate to the following path-

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft

Right-click on Microsoft > New > Key and name it as Edge.

Right-click on Edge > New > Key and name it as Recommended.

Right-click on Recommended > New > DWORD (32-bit) Value and name it as SleepingTabsEnabled.

Next, double-click on SleepingTabsEnabled to set the Value data as 1.

At last, click the OK button to save the change. It enabled the Sleeping tabs feature. However, if you want to set the background tab inactivity timeout, you need to create another DWORD value in the Recommended key and name it as SleepingTabsTimeout. Double-click on it > choose the Decimal radio button, and enter a value in seconds.

For instance, if you want to set it as 1 hour, enter 3600 and click the OK button.

It is also possible to turn off Sleeping tabs for a specific website. For that, right-click on Recommended > New > Key, and name it as SleepingTabsBlockedForUrls.

Right-click on SleepingTabsBlockedForUrls > New > String value and name it as 1.

Then, double-click on it, and enter the website URL as the Value data.

Click the OK button to save changes.

How to enable or disable Sleeping Tabs in Edge using Group Policy

It is required to download the Group Policy template for Microsoft Edge to use the Group Policy method.

To enable or disable Sleeping Tabs in Edge using Group Policy, follow these steps-

1. Press Win+R to open the Run prompt.
2. Type gpedit.msc and hit the Enter button.
3. Navigate to Sleeping Tabs settings in Computer Configuration.
4. Double-click on Configure Sleeping Tabs.
5. Choose the Enabled option and click the OK button.

Let’s delve into these steps in detail.

Computer Configuration > Administrative Templates > Classic Administrative Templates > Microsoft Edge - Default Settings > Sleeping Tabs settings

On your right-hand side, you can see a setting called Configure Sleeping Tabs. Double-click on it, select the Enable option and click on the OK button to save the change.

There are two more settings – Set the background tab inactivity timeout for Sleeping Tabs and Block Sleeping Tabs on specific sites.

To choose the inactivity timeout, double-click on the former setting, choose the Enabled option, expand the drop-down list, and choose a time according to your requirements.

If you want to disable Sleeping Tabs for a specific website, double-click on the latter setting, choose the Enabled option, click the Show button, enter the website URL, and click the OK button.

That’s all! Hope it helps.
