设备管理器^{(Device Manager)}是一个有用的Windows控制面板^{(Windows Control Panel)}小程序，它允许用户管理Windows PC 上的设备和驱动程序——甚至禁用特定的硬件。一些用户报告说他们发现设备管理器^{(Device Manager)}是空白的并且什么也没有显示。如果禁用关键Windows服务之一或注册表中^(Windows)设备管理器^{(Device Manager)}键的权限已损坏，则可能会发生这种情况。

设备管理器^{(Device Manager)}空白且不显示任何内容

如果您遇到此问题，以下是解决问题的方法。

1]启用即插即用^{(Enable Plug)}Windows^{(Play Windows Service)}服务

要正常运行，必须运行^(Play)即插即用^(Plug)服务。因此，要检查这一点，请在Start Search中键入^{(Start Search)}services.msc并按Enter打开Windows Services Manager。

向下滚动并找到“即插即用^{(Plug and Play)}”服务。

双击它并确保启动^(Startup)类型设置为自动^(Automatic)，如果服务未运行，请单击启动。^(Start)

验证问题是否已解决。如果没有，请跳到第二个选项。

2]编辑注册表权限

打开“运行”对话框，在框的空白字段中键入regedit ，然后^(regedit)按 Enter^(Enter)以打开Windows 注册表编辑器^{(Windows Registry Editor)}。接下来，导航到以下键：

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum

在这里，右键单击Enum并选择Permissions。如果组^(Group)或用户^(User)名列表框为空，那么您就知道这是问题所在！它应该有两个名字，System和Everyone。

单击添加^(Add)按钮并键入所有人^(Everyone)，然后单击确定。此外，选择标记为“读取^(Read)”选项的“允许”框。^(Allow)

完成后，再次单击Add并输入System。选中“读取^(Read)”旁边的“允许^(Allow)”框和“系统”的“^(System)完全控制^{(Full Control)}” 。它应该如下所示：

当您突出显示System^(System)时，应选中Allow下的两个复选框。单击确定^{(Click OK)}，如果弹出警告消息，只需单击确定。

最后，关闭注册表编辑器^{(Registry Editor)}并重新启动计算机。它应该有帮助。

3]重新注册DLL文件

要解决  设备管理器^{(Device Manager)}窗口为空白或白色的问题，您可以做的最后一件事是重新注册以下三个 dll 文件，看看是否有帮助。

• vbscript.dll
• jscript.dll
• mshtml.dll

这篇文章将向您展示如何注册 DLL 文件。

Device Manager is blank & not showing anything in Windows 11/10

Τhe Device Manager is a useful Windows Control Panel applet that allows a user to manage devices & drivers on a Windows PC – and even disable specific pieces of hardware. Some users have reported that they find that the Device Manager is blank and displays nothing. This can happen if one of the critical Windows service is disabled or if the permissions in the registry for the Device Manager key has corrupted.

Device Manager blank & not showing anything

If you face this issue, here’s how to fix the problem.

1] Enable Plug and Play Windows Service

To function properly, it is essential that the Plug and Play service has to be running. So, to check this, type services.msc in Start Search and hit Enter to open the Windows Services Manager.

Scroll down and find the ‘Plug and Play’ service.

Double-click on it and make sure the Startup type is set to Automatic and click Start if the service is not running.

Verify if the problem is solved. If not, jump to the second option.

2] Edit the registry permission

Open the ‘Run’ dialog box, type regedit in the empty field of the box and hit Enter to open the Windows Registry Editor. Next, navigate to the following key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum

Here, right-click on Enum and choose Permissions. If the Group or User names list box is empty, then you know this is the problem! It should have two names in there, System and Everyone.

Click the Add button and type in Everyone and click OK. Also, select the ‘Allow’ box marked against ‘Read’ option.

When done, click Add again and type in System. Check the ‘Allow’ box next to ‘Read’ and ‘Full Control’ for ‘System’. It should look like this:

Both the check boxes under Allow should be selected when you highlight System. Click OK and if a warning message pops up, just click OK.

Finally, close the Registry Editor and restart your computer. It should help.

3] Re-register DLL files

One last thing you could do to fix the problem of  Device Manager window being blank or white, would be to re-register the following three dll files and see if it helps.

• vbscript.dll
• jscript.dll
• mshtml.dll

This post will show you how to register DLL files.

Hope something here helps you!
