 ### Via an automatic One-Liner, that Downloads, installs and clean up
 This one-liner download and install does the following:
-    1. Sets the ExecutionPolicy
-    2. Stop the "Zabbix Agent 2" service.
-    3. Set the path where to store the script.
-    4. Download the script file to the path.
-    5. Create a scheduled task.
-    
-1. To run the script, you need to temporarily change the PowerShell execution policy to allow script execution. You can do this by using the following one-liner code:
+1. Sets the ExecutionPolicy
+2. Stops the "Zabbix Agent 2" service.
+3. Sets the path where to store the script.
+4. Downloads the script file to the path.
+5. Creates a scheduled task.
+6. Starts the newly created scheduled task.
 
-   ```powershell
-   Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass -Force; Stop-Service -Name "Zabbix Agent 2"; $scriptPath = "C:\Windows\System32\Tasks\CheckAndStartZabbixAgent2.ps1"; Invoke-WebRequest -Uri "https://gitlab.liu.se/andli86/snippets/-/raw/master/Windows/ZabbixAgent/CheckAndStartZabbixAgent2.ps1" -OutFile $scriptPath; schtasks /create /tn "CheckAndStartZabbixAgent2" /tr "powershell.exe -File $scriptPath" /sc hourly /mo 3 /ru SYSTEM;
