[- or: Information on theÂ red/green underliningÂ feature]
Â You may encouter the problem that, when you create a Preference item like the Regional Options and you save them and immediately after that (or some time later) you open them, the settings you made are just reverted to the defaults. You may also have noticed that the settings don’t get saved in the export XML file you can create — and also that this happens to settings, that have those fancy red underlines:
This is a feature with Group Policy Preferences. The issue goes back to the days when MS took over the product and “customized” to fit it into Windows Server 2008 and Vista RSAT now. The underlining you see under the setting simply dictates whether the setting will be applied by a client or not. Red means “clients won’t get that setting” - green means “clients will get that setting”. To switch between green and red, you need to use the function keys F5-F8:
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).
When changing the color of the underline, you will see the settings get saved.
