Set Date format on Windows devices

The following PowerShell script helps the IT Admins to change the date format on their managed Windows devices.

1. Create a file on your desktop, for example, set_date_format.ps1 and open it in a text editor like notepad++

2. Copy the contents below to the file or click here to download the file.

   1. ‘sShortDate’ key is to set Short date format, eg. D/M/yy (5/7/22)

   2. ‘sLongDate’ key is to set Long date format, eg. dddd, MMMM d, yyyy (Friday, January 5, 2024).

      $dateFormat = 'MM/dd/yyyy' 
      Write-Host "Starting script execution..." 
      try{ 
          $status = New-PSDrive -PSProvider Registry -Name HKU -Root HKEY_USERS 
          Function Set-DateFormat($sid) 
          { 
              if(Test-Path "HKU:\${sid}") 
              { 
                  Write-Host "updating date format for user:",$sid 
                  Set-ItemProperty -path "HKU:\${sid}\Control Panel\International\" -name 'sShortDate' -value $dateFormat 
              } 
      
          } 
          $userDetails=Get-wmiobject win32_useraccount | where-object{$_.status -eq 'ok'} 
          foreach($user in $userDetails){ 
              $sid=$user.SID 
              Set-DateFormat($sid) 
          } 
      } 
      catch 
      { 
          Write-Output "Error occured while running script -> ",$_.Exception.Message 
      } 
      Write-Output "Script execution completed successfully!"
