How can I globally adjust view sliders in W10 Pro?

OK, fair enough. Let's go back to square one. What happened when you used 'Apply to folders'?

It should have created a custom template based on the view settings of the folder you accessed the command from. That template is applied to both existing folders and any new folders that are the same folder type.

Check:

Code:

HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Streams\Defaults

to see if you have entries governing all the common types:

Code:

{5c4f28b5-f869-4e84-8e60-f11db97c5cc7} Generic                     
{5fa96407-7e77-483c-ac93-691d05850de8} Videos                      
{7d49d726-3c21-4f05-99aa-fdc2c9474656} Documents                   
{94d6ddcc-4a68-4175-a374-bd584a510b78} Music
