Hi Sajan,
Navigate to here:
C:\Users\Username\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup
Or click start and type "shell:startup"
Then here:
C:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUp
Or click start and type "shell:common startup"
Right click on the taskbar, and open Task Manager - click more details, then click the startup tab. See if your application is there.
Make sure it’s not in those locations, and disabled from task manager.
Let me know if this helps!
