我最近遇到了一个问题，我打开设备管理器^{(Device Manager)}发现它是空白的！空空如也！简直^(Just)是空空如也！这很奇怪，我花了一段时间才弄清楚问题所在！

如果您的设备管理器完全空白或为空^{(Device Manager is completely blank or empty)}，那么问题发生的原因有两种可能：您禁用了关键的Windows服务，或者您在注册表中对^(Windows)设备管理器^{(Device Manager)}项的权限已损坏。

以下是通过启用适当的Windows^(Windows)服务或更改注册表中的权限来解决此问题的方法。

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

显然，Windows 设备管理器^{(Windows Device Manager)}需要启用^(Play)即插即用^(Plug)服务才能正常工作。您可以通过转到“开始^(Start)”、“控制面板^{(Control Panel)}”、打开“管理工具^{(Administrative Tools)}”然后单击“服务”来启用该服务^(Services)。

向下滚动并找到即插即用^{(Plug and Play)}服务。双击^{(Double-click)}它并确保 启动类型^{(Startup type)}设置为自动^(Automatic)，如果服务未运行，请单击启动。^(Start)

检查您的设备管理器^{(Device Manager)}是否仍为空白。如果是，那么您还可以尝试通过转到Start、Run并输入MSCONFIG来启用更多 Windows 服务。单击“服务^(Services)”选项卡并选择“全部启用”^{(Enable All)}。

继续并重新启动您的计算机，您现在应该能够在设备管理器^{(Device Manager)}中看到所有硬件设备。如果没有，请尝试方法2^{(Method 2)}！

方法 2^{(Method 2)} –编辑^{(– Edit)}注册表权限^(Registry)

设备管理器^{(Device Manager)}可能为空的另一个原因是注册表中的密钥存在安全问题。要修复它，请单击Start，然后单击Run，然后输入REGEDT32。单击HKEY_LOCAL_MACHINE窗口或展开该配置单元并导航到以下键：

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum

现在右键单击Enum并选择Permissions。如果组^(Group)或用户名列表框为空，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。选中Read for Everyone旁边的Allow框。现在再次单击Add并输入System。选中Read and Full Control for System旁边的Allow框。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。在添加两个用户并选择重置所有子对象的权限条目^{(Reset permission entries on all child objects with entries shown here that apply to child objects)}后，请务必单击高级^(Advanced)按钮，此处显示的条目适用于子对象。

单击确定^{(Click OK)}，如果出现警告消息，只需单击确定。关闭^{(OK. Close)}注册表编辑器并重新启动计算机。您现在应该能够在设备管理器^{(Device Manager)}中看到所有内容。

如果您仍然对空白设备管理器^{(Device Manager)}有问题，请在此处发表评论！享受！

Device Manager Empty or Blank in Windows?

I recently had a problem where I opened my Deviсe Mаnager and foυnd that is was blank! Nothing there! Jυst plain empty! It was verу ѕtrange and it took me a while to figure out whаt the рroblem was!

If your Device Manager is completely blank or empty, then there are two possibilities of why the problem is occurring: either you have a critical Windows service disabled or your permissions in the registry for the Device Manager key are corrupt.

Here’s how you can fix this issue by enabling the appropriate Windows service or changing the permissions in the registry.

Method 1 – Enable Plug and Play Windows Service

Apparently, the Windows Device Manager needs to have the Plug and Play service Enabled in order to work correctly. You can enable the service by going to Start, Control Panel, opening Administrative Tools and then clicking on Services.

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.

Check to see if your Device Manager is still blank or not. If it is, then you can also try to enable more Windows Services by going to Start, Run and typing in MSCONFIG. Click on the Services tab and choose Enable All.

Go ahead and restart your computer and you should now hopefully be able to see all the hardware devices in Device Manager. If not, try Method 2!

Method 2 – Edit the Registry Permissions

The other reason Device Manager may be empty is because there are security issues with the key in the registry. To fix it, click on Start, then Run, and type in REGEDT32. Click on the HKEY_LOCAL_MACHINE window or expand that hive and navigate to the following key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum

Now 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. Check the Allow box next to Read for Everyone. Now 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. Also be sure to click on the Advanced button after adding both users and selecting Reset permission entries on all child objects with entries shown here that apply to child objects.

Click OK and if a warning message comes up, just click OK. Close the registry editor and restart your computer. You should now be able to see everything in the Device Manager.

If you are still having problem with a blank Device Manager, post a comment here! Enjoy!
