Oscar Villarino ,

You need to go to the top right hand side of Trados Studio and click this button:

Then select Show Tabs and Commands:

FYI: You probably pressed CTRL+F1 shortcut or clicked on this little arrow:

BTW: the shortcut and the arrow are in the Microsoft Office applications as well.

Thanks, Jesus, is not the ribbon but the pane, on the left side.

see also  Navigation pane too narrow

Ups! Sorry.

This is the Minimise button:

And the maximize button:

If there is no Maximise button, try View > Reset Window Layout

thanks, i could not retrieve the normal layout and I updated to 2022 version. 

so issue resolved

regards

I know it's been a million years since this question was asked, but I'm in the same situation... it's very uncomfortable to use. Did anyone find out how to solve it? Thanks!!

If following the advice from Jesús didn't help you then reset and that should do it.  

To do this just close Trados Studio and then rename this folder (I based this on 2021 since you didn't state the version you use):

c:\Users\%username%\AppData\Roaming\SDL\SDL Trados Studio\Studio16\

to c:\Users\%username%\AppData\Roaming\SDL\SDL Trados Studio\Studio16_old\

If you can't find this folder then you need to unhide your hidden files/folders:

Then restart Trados Studio and see if that helped.
