[CCleaner persistently starts with Windows]

Thank you very much.

[CCleaner persistently starts with Windows]

CCleaner starts with Windows even though startup options are turned off everywhere.

   Windows 10 Home 64-bit
   version: 21H2
   OS build: 19044.1645
   Windows Feature Experience Pack 120.2212.4170.0

In CCleaner
• Settings >> "Run ... when you start Windows" is unchecked
• Smart Cleaning >> "Enable Smart Cleaning" is unchecked

In Windows
• Settings >> Apps >> Startup >> CCleaner is toggled Off
• Task Manager >> Startup tab >> CCleaner is Disabled
• no shortcut in %AppData%\Microsoft\Windows\Start Menu\Programs\Startup\

What else could be starting up CCleaner automatically?
