Hello, Mateus Almeida
Welcome to Microsoft Q&A,
Thank you for your feedback. If you want to do this via the command line, PowerShell is a powerful tool. It essentially modifies the registry keys related to regional formats.
Open PowerShell as an administrator.
Execute the following command. You can choose one of them as needed.
To set the format to “Wednesday, 07/17/2025”:
Set-ItemProperty -Path “HKCU:\Control Panel\International” -Name ‘sShortDate’ -Value “dddd, MM/dd/yyyy”
To set the format to “Wednesday, July 17, 2025”:
Set-ItemProperty -Path “HKCU:\Control Panel\International” -Name ‘sShortDate’ -Value “dddd, MMMM dd, yyyy”
Apply changes: After executing the command, the changes may not take effect immediately on the taskbar. You need to restart File Explorer (explorer.exe) to load the new settings. Execute the following command in the same PowerShell window:
Stop-Process -Name explorer -Force
(Your taskbar and desktop will disappear, which is normal. It will restart automatically. If it doesn't restart automatically, manually press Ctrl+Shift+Esc to open Task Manager, click “File” -> “Run new task,” enter explorer.exe, and press Enter.)
Regarding third-party software, such as ExplorerPatcher or StartAllBack, you can try them, but they are not recommended.
I look forward to your feedback.
