How to fix
The “Error 1075: The dependency service does not exist or has been marked for deletion”
on Windows

A couple of days ago, I installed Windows 10 update, which caused my WiFi adapter to stop working. At the moment, I receive this error message: “Error 1075: The dependency service does not exist or has been marked for deletion.” What should I do? Thanks in advance!

The “Error 1075: The dependency service does not exist or has been marked for deletion” error has been bugging people since the last decade, and troubles still persist. Most people reported that this error typically occurs after installing Windows updates.

The problem seems to be related to the dependency service and often happens to occur when trying to open Security Center, Microsoft Exchange, Print Spooler, Themes, or any other service. According to Windows experts, the Error 1075 might have been triggered by the latest Windows 10 update, which might have caused driver malfunction or removal of some system components for whatever reasons.

Windows could not start the Security Center service on Local Computer.
Error 1075: The dependency service does not exist or has been marked for deletion.

The error message (above) is quite informative as it indicates the culprit so that it would be easier to address the issue. Evidently, it is related to the dependency service, so it’s important to find out what system components stopped from running properly leading to the crash of the dependent service and the emergence of the Error 1075.

However, usually, it's not possible to check the dependent services because the Dependencies tab on the Security Center window displays two empty boxes and provides zero explanation. Luckily, a simple registry modification should help you to fix “Error 1075: The dependency service does not exist or has been marked for deletion,” so don’t wait any longer and try to perform the following steps.

TIP: Before you proceed with modifying the registry, we would like you to make sure that the malware is not causing errors on your Windows machine. For that, we suggest you download and install [rev id=“Reimage"], and then perform a full system scan. It is vital in case your computer is showing other symptoms, including slow performance, crashing or freezing applications, high CPU/GPU usage, frequent BSoDs, etc.

Option 1. Delete registry entry

• Click Windows key + R, type regedit, and press Enter
• If a UAC opens, click Yes to proceed
• Use the left pane to navigate to the HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\Dhcp directory
• Right-click on DependOnService entry and then click Delete

  

Option 2. Scan your system using System File Checker

• Type in cmd into the search box in the taskbar
• Right-click on Command Prompt and select Run as administrator
• When the new window opens, type in sfc /scannow and hit Enter
• Wait till Windows scans your computer (it might take a while)
• If any bugs are found, Windows will fix them automatically
• Restart your machine

  

Option 3. Flush DNS settings

• Open Command Prompt (as administrator)
• Once the window opens, type in ipconfig /flushdns
• You should receive a message reporting that the DNS resolver cache is flushed
• Reboot your machine

Option 4. Update your network adapter driver

Drivers are imperative when it comes to any Windows machine. They ensure that hardware and software communicate properly; if something goes wrong with a driver, Windows might start malfunctioning. Instead on relying on a Device Manager, we highly recommend you download the latest driver from the manufacturer's website or employ an automatic driver updater [rev id="DriverFix"].

• Right-click on the Start button and select Device Manager
• In the Device Manager window, expand the Network Adapters pane
• Choose your main network adapter device, right-click on it and select Update Driver
• If Windows finds new drivers, let it install them (just follow on-screen instructions)
• Reboot your PC

  

Option 5. Set the services to start up automatically

• Right-click on the Start button and select Run
• Type in services.msc and click OK
• Scroll down and find Windows Defender Firewall
• Right-click and select Properties
• Under the General tab pick Automatic as the startup type
• Restart the service by right-clicking on it and selecting Restart
• Do the same with Windows Management Instrumentation and restart the service

  

Option 6. Ensure service dependencies are running

Some services might be unable to start because of its dependencies aren't running. Here's how to check this:

• Open Services once again
• Right-click on the service you are having problems with and select Properties
• Go to the Dependencies tab
• Check which services are required to be running

  

• Find the service on the list, right-click, and select Start
• If you are unable to start the service, open PowerShell as administrator (right-click on Start and pick PowerShell(Admin)
• Type Get-Service and press Enter

  

• Find the service name you are unable to start
• Now copy in the following command, replacing "Servicename" with the relevant service (keep the brackets):
  Set-Service -Name "Servicename" -Status running
• Restart your PC.
