How to Change Windows 10 Pro Language and Region Settings

Moving countries, travelling for work, or sharing your PC with relatives from another part of the world can quickly turn small Windows quirks into daily frustrations. Dates appear in a format you do not recognise, invoices quote the wrong currency, and weather apps show temperatures in Fahrenheit when everyone around you talks in Celsius. Adjusting the language and regional preferences inside Windows 10 Pro solves most of those irritations in a few clicks, and you do not need to reinstall the operating system to do it.

This walkthrough covers everything from switching the on-screen display language and installing a fresh language pack, through to changing the regional format for dates, numbers, and currency, picking the right time zone for Australia, and tweaking the system locale used by older applications. Each step uses the built-in Settings app, so nothing has to be downloaded from third-party sites.

A few Australian specifics are woven through the guide, because choices like the AEST and AEDT time zones, the Australian dollar symbol, and the day-first date format only become obvious once your PC is set up correctly for life in Sydney, Melbourne, Brisbane, or anywhere else across the country.

Opening the Settings App in Windows 10 Pro

The fastest way to reach every language and region option is through the Settings app, which replaced the older Control Panel for most everyday tasks in Windows 10 Pro. Click the Start button, type "Settings" into the search box, then press Enter when the System Settings result appears. The Settings window opens with a row of tiles along the left-hand side and a list of categories on the right.

If you prefer keyboard shortcuts, press Windows + I to jump straight to the same panel from anywhere on the desktop. That is handy if you are working in another application, such as a spreadsheet full of customer records or a browser tab comparing flight prices, and you suddenly realise the dates are showing in the wrong order.

From the home screen, choose "Time & Language" to see three groups of options: Date & Time, Region, and Language. Each group leads to its own dedicated page, and the changes you make are saved the moment you close a flyout or click away from a dropdown. There is no big "Apply" button, which makes experimentation painless if you are not sure what you want yet.

Switching the Display Language in Windows 10 Pro

The display language controls the text used across menus, dialog boxes, and built-in apps such as File Explorer, Microsoft Edge, and the Settings app itself. Inside Time & Language, click "Language" in the left column to see the list of preferred languages currently installed on the device. If English (Australia) is already at the top, you are essentially done for everyday use, but you might still want to add a second language for spelling checks or handwriting recognition on a touchscreen laptop.

To add another language, press "Add a language" and scroll through the alphabetical list until you find what you need. Australia is home to communities speaking well over 200 languages, so do not be surprised if you scroll for a while to find Mandarin, Vietnamese, Greek, Italian, or Arabic among the options. Pick the language you want, select any optional features such as speech or handwriting, and wait a few seconds for Windows to download the pack.

Once the new language appears in the list, click it and choose "Set as default" to move it to the top. Windows will ask you to sign out and back in for the change to fully take effect, so save any open documents first. After signing back in, the Start menu, taskbar, and notification area should appear in the freshly chosen language, while individual apps will gradually follow as you reopen them.

If a language does not show up in the standard list because it ships as an optional Local Experience Pack, head to the Microsoft Store, search for the language name, and install the free pack offered by Microsoft. This is the method used for several less common languages that are still supported on Windows 10 Pro.

Adjusting Regional Format for Date, Time, and Currency

Region settings are what give your numbers, dates, and currency symbols their local flavour. In the same Time & Language area, click "Region" to see a dropdown labelled "Country or region." Choose "Australia" to make Windows automatically match the conventions used in Sydney, Melbourne, Perth, and other Australian centres, including the Australian dollar symbol, the first day of the week falling on Monday, and decimal points instead of commas in numbers.

The "Regional format" dropdown underneath lets you choose a specific cultural format even if you keep your country set to Australia. For example, you might keep English (Australia) as the display language but switch the regional format to English (United Kingdom) if you often deal with British suppliers, or to English (United States) if you work remotely for an American company. Each option changes how dates appear in File Explorer, how Excel displays currency, and how the calendar in the taskbar shows the week.

Scroll a little further and you will find individual toggles for short date, long date, short time, and first day of the week. Australian users typically prefer the dd/MM/yyyy format for printed invoices and accounting software, even though ISO recommends yyyy-MM-dd for technical documents. If you need to send spreadsheets to overseas clients who prefer MM/dd/yyyy, switching the system format here is much easier than retyping every column.

Additional settings, hidden behind a link called "Additional date, time, and regional settings," open the old Control Panel for fine-tuning. That is where you can change the default decimal symbol, the digit grouping, and the list separator used by older accounting packages that still read the system locale directly.

Picking the Right Time Zone for Australian Cities

Time zone mistakes cause more missed meetings than almost any other setting, particularly between states that observe daylight saving and those that do not. From the Time & Language category, click "Date & Time" and make sure "Set time automatically" is turned on, so Windows can sync with the time servers and keep your clock accurate to the second without manual fiddling.

Underneath, choose the correct time zone from the dropdown. Australians in New South Wales, Victoria, Tasmania, the ACT, and South Australia pick "UTC+10:00 Canberra, Hobart, Melbourne, Sydney" during standard time and switch to "UTC+11:00" once daylight saving begins in early October. Queensland sticks with UTC+10:00 all year, which is why Brisbane meetings can quietly drift one hour away from Adelaide if you forget to update your calendar invite.

Western Australia uses UTC+08:00, so devices roaming between Perth and the eastern capitals need the zone updated during travel. The Northern Territory uses UTC+09:30 and, like Queensland, does not observe daylight saving. If you travel frequently between, say, Sydney and Perth for work in mining or agriculture, a quick check of this dropdown at the start of each trip saves a lot of confusion with colleagues.

When daylight saving starts in NSW, Victoria, South Australia, Tasmania, and the ACT, Windows usually updates the clock overnight on the first Sunday of October, so double-check the change the next morning if you have an early meeting. The reverse happens on the first Sunday of April, when clocks fall back an hour and the dropdown should automatically read UTC+10:00 once again.

Updating the System Locale for Older Programs

Many Australian businesses still rely on line-of-business applications written in Visual Basic, FoxPro, or older .NET frameworks. These programs do not always read the modern region settings and instead look at something called the system locale, which is a legacy character set and language preference. Updating it ensures that programs imported from overseas display translated menus and handle text correctly without needing per-application patches.

Scroll to the top of the Language page and click "Administrative language settings," found under the "Related Settings" header. A new window opens showing the current language for non-Unicode programs and the system locale. Click "Change system locale," pick "English (Australia)" from the list, and tick the box labelled "Beta: Use Unicode UTF-8 for worldwide language support" only if your software supports it.

Some Australian government portals, including certain myGov-integrated services and legacy Centrelink desktop tools, were originally built for English (Australia) code pages and still behave best when the system locale matches that choice. Saving the change asks you to restart, so save work in Outlook, web browsers, and any open spreadsheets before clicking "Restart now."

After the reboot, log in and open one of the legacy apps to confirm that menus, prompts, and currency fields all reflect Australian English. If characters appear as squares or question marks, the locale has been set to a region whose default code page does not match the source data, so revisit the menu and try a different option such as English (United Kingdom) before giving up on the program.

Managing Input Methods and Keyboard Layouts

Multilingual households often mix scripts on a single device, especially in cities such as Melbourne and Sydney where Mandarin, Cantonese, Greek, and Italian are widely used alongside English. The Language page also lets you add or remove input methods, which control what appears when you press a key on the physical keyboard.

Click an installed language in the list, choose "Options," and you can add a second keyboard layout such as US International, Dvorak, or another country's standard. The system language bar, which appears in the taskbar when multiple layouts are installed, lets you switch with a single click or by pressing the Windows key and spacebar together.

If you only need a single layout, leave the default Australian English keyboard selected and remove any extras that you do not use. Extra layouts can confuse typing in password fields and remote desktop sessions, particularly on Windows 10 Pro machines joined to Active Directory domains, so removing them tightens security and reduces typos.

Verify Everything With Built-In Apps

After applying the language, region, time zone, and locale changes, spend a few minutes testing the results. Open File Explorer and right-click inside a folder to choose "New" then "Text Document," and the modified date stamp in the file properties should reflect the chosen short date format. Launch the Calculator app and type a calculation with decimals to confirm that the decimal symbol is what you expect.

Open the Microsoft Store, search for a free Australian news app from a major publisher, and check that headlines, dates, and prices appear correctly. Open Outlook or the Mail app and confirm that meeting times are right for Sydney time, and that public holiday banners such as those for Australia Day on 26 January and ANZAC Day on 25 April appear on the right day without manual calendar entries.

If anything still looks off, revisit the relevant section above and adjust the setting again. Changes are non-destructive, so flipping a dropdown back and forth costs nothing more than a fresh sign-out when required, and you can keep tweaking until every app, document, and calendar entry looks the way you want.

If you want to keep your file organisation tidy while you refresh these settings, the guide on change the default save location walks through moving default save locations for documents, downloads, pictures, and music so your freshly formatted content lands in the right folder from the first save.
