I installed 11.6

[Maureen L Thomas]

I installed debian 11.6 and updated the needed packages to 11.7. I must 
say that I hate upgrading because they change everything and I cannot 
find the utilities I need to make this the way I want it.  Does anyone 
know which utility changes the window settings. Like the X in the upper 
right hand corner.  I want all three items including the - and the box.

Thank you guys for all your help.
