When you are using GPO prefernces to set Regional Settings on computers or Citrix / Terminal Servers you might see that even if you change to the region
you want to use it is not saved the next time you open the GPO . And the name of the Regional setting is End User Default Local instead of the name of the region.
In my case Swedish (Sweden).
If you read in the GPO you see :
This option affects how some programs format numbers, currencies, dates, and time.
The enabled (green underline) selected locale will become the end-user’s default locale when this policy is applied otherwise all settings apply to the end-user’s default locale. the locale may be customized on subsequent property pages.
The keyword here is the green underline.
But how do you get the green underline?
The answer is simple when you know it. You need to use the F5 – F8 key’s
F5 – Mark all settings on the page as “green” (apply all)
F6 – Mark current setting as “green” (apply this setting)
F7 – Mark current setting as “red” (don’t apply this setting)
F8 – Mark all settings on the page as “red” (don’t apply).
Have fun GPO-ing
