昨天我去安全中心^{(Security Center)}检查时，我才知道我的系统上没有运行Windows 防火墙服务。^{(Windows Firewall)}所以我通过按运行services.msc命令前往 本地服务窗口。^{(Local Services)}在这里，我发现只有少数服务正在运行。我试图启动剩余的服务，但我无法这样做。我收到 错误 0x80070005，访问被拒绝^{(Error 0x80070005, Access is Denied )}消息。这是其中一项服务的屏幕截图：

Windows could not start the Block Level Backup Engine Service on Local Computer, Error 0x80070005, Access is Denied.

由于此 访问被拒绝^{(Access is denied)}错误，我无法启动大多数本地服务，这使我的系统出现警告和警报。最初，为了解决这个问题，我确实运行了SFC /SCANNOW命令来修复与这些服务相关的任何损坏的文件，但这对情况没有任何影响。

最终，我找到了这个解决方案，它帮助我显着解决了这个问题：

Windows 无法启动服务^(Service)，错误 0x80070005^{(Error 0x80070005)}，访问被拒绝^{(Access Is Denied)}

1.按Windows Key + R组合， 在运行对话框中键入Regedt32.exe ，然后^{(Regedt32.exe)}按 Enter^(Enter)打开注册表编辑器^{(Registry Editor)}。

2.导航到以下位置：

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\wcncsvc

3.在该位置的左窗格中，右键单击wcncsvc键并选择权限^{(Permissions)}。在Permissions窗口中，突出显示Administrators条目。

4.确保就权限^{(Permissions)}而言，您已选中完全控制^{(Full control)}选项。确保与用户^(Users)条目相同。

在两种情况下都单击应用^(Apply)，然后单击确定。^(OK)最后，关闭注册表编辑器^{(Registry Editor)}并重新启动系统。您现在应该能够毫无障碍地启动本地服务。

This should help solve the problem on Windows 11/10.

错误 0x80070005^{(Error 0x80070005)}相当普遍，在以下场景中也会显示此代码：

• 我们无法设置您的默认保存位置^{(We couldn’t set your default save location)}
• 办公钥匙安装^{(Office Key installation)}
• 一个驱动器^(OneDrive)
• Windows 激活^{(Windows Activation)}
• IPersistFile 保存失败^{(IPersistFile Save failed)}
• 系统还原^{(System Restore)}
• Windows 应用商店应用^{(Windows Store apps)}
• Windows更新^{(Windows Update)}
• 任务计划程序
• 在更新 Chrome 时^{(While updating Chrome)}。

Windows could not start Service, Error 0x80070005, Access Is Denied

Υesterday when I went to check the Security Center, I came to know that the Windows Firewall service wasn’t running on my system. So I headed to the Local Services window by pressing running services.msc command. Here I found that only a few services were running. I tried to start the leftover services, but I wasn’t able to do so. I received Error 0x80070005, Access is Denied message. This is the screenshot with one such service:

Windows could not start the Block Level Backup Engine Service on Local Computer, Error 0x80070005, Access is Denied.

Due to this Access is denied error, I couldn’t start most of the local services, and this messed up my system with warnings and alerts. Initially, to fix it out, I did run the SFC /SCANNOW command to fix out any corrupted files associated with these services, but it didn’t make any difference in the situation.

Then eventually, I came around this solution which helped me to resolve the issue significantly:

Windows could not start Service, Error 0x80070005, Access Is Denied

1. Press Windows Key + R combination, type Regedt32.exe in the Run dialog box and hit Enter to open the Registry Editor.

2. Navigate to the following location:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\wcncsvc

3. In the left pane of this location, right-click over the wcncsvc key and select Permissions. In the Permissions window, highlight the entry Administrators.

4. Make sure you have the Full control option checked as far as Permissions is concerned. Ensure the same with Users entry as well.

Click Apply followed by OK when down in both cases. Finally, close the Registry Editor and reboot the system. You should now be able to start local services without any hitch.

This should help solve the problem on Windows 11/10.

Error 0x80070005 is rather ubiquitous and this code is also displayed in the following scenarios:

• We couldn’t set your default save location
• Office Key installation
• OneDrive
• Windows Activation
• IPersistFile Save failed
• System Restore
• Windows Store apps
• Windows Update
• Task Scheduler
• While updating Chrome.
