Modifying some settings in a PowerShell script
with get/set-culture
The PowerShell cmdLet nount
culture can be used to modify some (all) values in this
registry key:
$culture = get-culture
# Value being is changed
# --------------------------
$culture.dateTimeFormat.shortDatePattern = 'yyyy-MM-dd' # sShortDate, sDate, iDate
$culture.dateTimeFormat.shortTimePattern = 'HH:mm' # HH is supposed to be 24 hours, why does it not seem to be working.
$culture.dateTimeFormat.pmDesignator = '' # Don't show AM/PM
$culture.numberFormat.currencyPositivePattern = 2 # iCurrency
$culture.numberFormat.CurrencySymbol = 'EUR' # sCurrency
#
# Changing the list separator seems to
# be broken.
# https://github.com/dotnet/runtime/issues/43795
# use list-separator.ps1 instead.
#
#
$culture.textInfo.listSeparator = ',' # sList
set-culture $culture
With set-itemProperty
In fact, this method seems to be required in order to have a 24-hours without AM/PM designator, as per
this superuser answer.
The following
PowerShell script changes some of format settings that are specified in this registry key:
set-itemProperty 'hkcu:\Control Panel\International' sShortDate 'yyyy-MM-dd'
set-itemProperty 'hkcu:\Control Panel\International' sShortTime 'HH:mm' # Seconds not possible?
I am not sure what the best way is to apply the modifications after the script is run. Maybe something like the following:
get-process explorer | stop-process
explorer
