How to add an application to startup in Win 10?

Question

Windows

Hello. On win 10 I can not add the application to startup. Before that, it was possible through an entry in the registry, but I reinstalled the operating system, now it doesn’t work in any way.
Tried:
Add a shortcut to the startup folder of the start menu.
Add a key to the registry. Tried to shove the key in both HCLM and HCLU.
Add a task in Task Scheduler.
Add program launch via group policy.
The registry entry and Start menu shortcut show up in Task Manager, but it doesn't start. The task hangs in the scheduler, but does not start itself. If you click with the mouse and execute, the launch will occur.
Administrator account, all access rights to the file are given.

Answer 1

Problem solved. In the task scheduler, I added a task, in the settings, instead of my account, I specified "Administrators" and launch at login, instead of launch at startup.

Answer 2

try the task manager, there is an autorun tab, or whatever it's called

Answer 3

You can manually put the shortcut in the startup folder
C:\Users\UserName\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup
