Quick fix: Run control intl.cpl from Run dialog to open the legacy Region applet directly. For language/keyboard, run control input.dll. These dialogs still work in Windows 11 even as the new Settings deprecates parts of them.
You want the old Control Panel Region dialog — the one with explicit Format dropdowns, currency, number, date, time customization tabs. The new Settings → Time & language has a stripped-down version that doesn’t expose all the per-locale options.
Affects: Windows 11 (any edition).
Fix time: 2 minutes.
What the legacy applets still offer
The classic Region dialog (intl.cpl) has: Format selection per category, Customize button for fine-grained number/currency/time/date formats, locale comparison, and direct keyboard layout management. The new Settings exposes the most common options but hides Customize.
Method 1: Direct Run command
- Win+R, type
intl.cpl, press Enter. The legacy Region dialog opens. - Tabs: Formats (date/time/number/currency), Administrative (system locale, regional language packs), Location (legacy — not used much).
- Click Additional settings in Formats for currency symbol, decimal separator, etc.
Method 2: Pin the shortcut
- Right-click the desktop → New → Shortcut.
- Target:
control intl.cpl. - Name: Region (legacy).
- Use whenever you need granular control.
Method 3: Access via Settings shortcut
- Settings → Time & language → Language & region.
- Click Regional format, then Change formats.
- If this doesn’t expose what you need, return to Method 1.
Verification
- intl.cpl opens the legacy dialog with all tabs visible.
- Changes save and apply system-wide.
If none of these work
For chronic Region settings management, use PowerShell’s Set-Culture and Set-WinUserLanguageList cmdlets. They expose programmatic access to everything the legacy dialog shows plus deployment-friendly features. The legacy dialog is the GUI; PowerShell is the script.
Bottom line: Legacy applets still work via Run. intl.cpl is the direct path to the classic Region dialog Windows 11 hides.
