Suat, moving the Start to the left is no longer
a registry hack, it's in the Taskbar Settings now.
Thank you CrazyKats for the reminder.
My point is, I open Start Menu and it opens above the Start Menu button where Start Menu button is located. Left or Center of Task Bar.
I open Task Manager. Task Manager opens where I had dragged it before. Task Manager is free to move and it stays where it is moved to. I didn't check how it behaves between reboots.
I open Run dialog box. It opens at the left bottom corner above the Task Bar. I drag it somewhere else. A second later I re-open it. It opens again at the left bottom corner above the Task Bar.
This no no big deal by the way.
I put the subject forward here for the sake of Windows behavioral consistency.
Kind regards
