3. Update your network adapter driver. Outdated or faulty drivers can cause network problems. Visit the manufacturer’s website to download and install the latest driver for your network adapter.
4. Grant Administrator privileges to the Diagnostics Policy Service. Right-click on the Service and select “Properties”. Go to the “Log On” tab and check the box for “Allow service to interact with desktop”.
Checking the status of the Diagnostics Policy Service
To check the status of the Diagnostics Policy Service, follow these steps:
1. Press the Windows key + R to open the Run dialog box.
2. Type “services.msc” and press Enter to open the Services window.
3. Scroll down and locate the “Diagnostics Policy Service” in the list.
4. Check the “Status” column to see if the service is running or stopped.
5. If the service is stopped, right-click on it and select “Start” from the context menu.
6. If the service is already running, but you’re still experiencing issues, you can try restarting it by right-clicking on it and selecting “Restart”.
7. If you’re unable to start or restart the service due to access denied or error 5, you may need to run the command prompt as an administrator. To do this, press the Windows key, type “cmd”, right-click on “Command Prompt”, and select “Run as administrator”.

python
import subprocess
def is_service_running(service_name):
# Use the 'sc' command to query the service status
cmd = f'sc query {service_name}'
output = subprocess.check_output(cmd, shell=True).decode()
# Check the output to determine if the service is running or not
return 'STATE' in output and 'RUNNING' in output
# Usage example
if is_service_running('DPS'):
print("Diagnostics Policy Service is running.")
else:
print("Diagnostics Policy Service is not running.")
Please note that this code snippet utilizes the `subprocess` module in Python to execute the `sc query` command, which retrieves the status of the given service name. However, running this code might require administrative privileges, and the service name may vary depending on the Windows version and configuration.
