Customizing currency formats in Windows can be essential for users who work with different currencies or need to adhere to specific regional settings. Windows provides built-in options to adjust currency formats through its Control Panel and also allows for automation via PowerShell scripts.

Examples:

1. Using Control Panel:

   • Open the Control Panel by searching for it in the Start menu.
   • Navigate to "Clock and Region" and then click on "Region."
   • In the Region dialog box, click on the "Formats" tab.
   • Click on the "Additional settings..." button.
   • Switch to the "Currency" tab.
   • Here, you can customize various aspects of the currency format, including the currency symbol, number of decimal places, and the format for positive and negative currency amounts.
   • After making your changes, click "OK" to apply them.

2. Using PowerShell:

   PowerShell can be used to retrieve and set regional settings, including currency formats. Here's how you can use PowerShell to view and change currency settings:

   • View Current Currency Format:

     Get-Culture | Select-Object -ExpandProperty NumberFormat | Format-List Currency*

   • Change Currency Symbol: To change the currency symbol, you can modify the registry settings using PowerShell. Note that changing registry settings can affect system stability, so proceed with caution and ensure you have backups.

     Set-ItemProperty -Path 'HKCU:\Control Panel\International' -Name 'sCurrency' -Value '€'

   • Apply Changes: After making changes to the registry, you might need to restart your computer or log off and log back in for the changes to take effect.

3. Using Command Prompt (CMD):

   While CMD does not directly allow for changing currency formats, you can use it to open the Control Panel or execute PowerShell scripts.

   • Open Control Panel via CMD:

     control.exe /name Microsoft.RegionAndLanguage

   • Execute a PowerShell script from CMD:

     powershell.exe -File "C:\Path\To\Your\Script.ps1"
