WL10 on launching shows plugin windows and presets

On each launch WL10 randomly opens few or all plugin windows and presets managers from Master section and clusters them across workspace. That is quite annoying and time consuming as it loads all that GUIs.
But even more annoying is as I have to close each window before getting to work.
Is there an option to disable this?
thank you

Try to disable this option:

Hi PG1.
Thank you for kind suggestion. My Master section is fine now - no all around opened windows anymore!
But I got a funny situation as WL refuses to reopen if closed. I have to reboot windows computer (XMG CORE15 )… Time to open another tread…
all best
