@destroy666 said in Lost all data after autostart with system, not sure how to proceed:
As for autostart, that doesn't help. The issue is that the installer for some reason has adding autostart entry enabled by default. I worked around it by adding a parameter to the package manager I'm using - chocolatey.
Does Chocolately do the updates for Opera too or just the initial install? If the former and Chocolately uses the full installer to update and you're telling Chocolately to pass --run-at-startup=0 to the installer, I wonder if that switch is just broken like you suspect.
