Default means the setting or program a device uses when you don't pick something else
When your computer, phone, or tablet does something automatically without asking you first, it is using a default. A default is the built-in choice that comes with the device or software. If you open a link and it goes straight to Chrome instead of Firefox, Chrome is your default browser. If you take a photo and it saves to Pictures instead of Documents, Pictures is your default folder. The device made that choice for you because you never told it to do something different.
Defaults exist because devices need to know what to do in every situation. Without them, your phone would ask you which app to use every single time you clicked a link, opened a file, or took a photo. That would be exhausting. Instead, manufacturers and software makers pick one option ahead of time and use that unless you change it. You can change almost any default, and you should if the automatic choice does not match what you actually want.
Key Takeaways
- A default is the automatic choice your device makes when you do not pick one yourself, like which browser opens when you click a link.
- Defaults are set by the manufacturer or software maker, but you can change most of them to match your own preferences.
- Common defaults include your default browser, default email program, default printer, and default folder for saving files.
- Changing a default is usually done in Settings, Preferences, or the program itself, and the change stays until you switch it again.
Common defaults on computers and phones
Your device has dozens of defaults, but you will notice only a few because they affect what you do every day. Your default browser is the program that opens when you click a link in an email or text message. Your default email program is what launches when you click an email address. Your default printer is the one your computer sends documents to unless you pick a different one. Your default search engine is what appears when you type in the address bar — usually Google, but it could be Bing or something else.
On phones and tablets, defaults matter just as much. Your default camera app is which one opens when you press the camera button. Your default messaging app is what sends texts when you reply to a message. Your default maps app is which one opens when you click an address. Windows computers, Macs, iPhones, and Android phones all let you change these, though the steps are different on each one. The point is the same: if the automatic choice bothers you, you can pick something else.
How to change a default on Windows
On a Windows computer, most defaults live in Settings. Open Settings by pressing the Windows key and typing "Settings," then click the app that appears. Look for a section called "Apps" or "Default apps" — the exact name changes depending on your Windows version. Click it, and you will see a list of categories like "Web browser," "Email app," and "Maps." Click the category you want to change, and Windows shows you what is currently set as the default. Click that and choose a different program from the list that appears.
For your default printer, the path is slightly different. Open Settings, go to "Devices," then "Printers and scanners." You will see a list of printers connected to your computer. Click the one you want to use by default, then click "Manage" and look for an option that says "Set as default." On older Windows versions, you may need to right-click the printer name instead. If you do not see your printer in the list, it is not connected to your computer yet — you will need to add it first.
How to change a default on a Mac
On a Mac, defaults are usually in System Preferences or System Settings, depending on your macOS version. Click the Apple menu in the top-left corner, then select "System Preferences" or "System Settings." Look for "General" or search for the type of default you want to change — for example, search for "default browser" and macOS will take you straight there. Click the dropdown menu next to the current default and pick a different program.
For your default printer on a Mac, open System Preferences or System Settings and go to "Printers and Scanners." Right-click the printer you want to use by default and select "Set as default printer." If your printer is not in the list, click the plus sign to add it. Macs also let you set defaults for which program opens certain file types — for example, which program opens PDF files. Right-click any file of that type, select "Open With," choose the program you want, then click "Always Open With" to make it the default.
How to change a default on iPhone and iPad
iPhones and iPads have fewer defaults than computers, but the ones that exist matter. To change your default browser or email app, open Settings and scroll down to find the app name — for example, "Chrome" or "Gmail." Tap it, and you will see an option for "Default Browser App" or "Default Email App." Tap that option and choose which program you want to use. The change takes effect immediately, and the next time you click a link or email address, your new default opens instead.
You can also set defaults for maps, messaging, and phone calls on iPhone. The process is the same: open Settings, find the app, and look for a default option inside it. Not every app offers this choice — it depends on what the app does and whether Apple allows it. If you do not see a default option for something you want to change, that app may not support it yet.
How to change a default on Android phones
Android phones store defaults in Settings, but the exact location varies by manufacturer and Android version. Open Settings and look for "Apps," "Applications," or "App Management." Find the app you want to change — for example, your browser or email program. Tap it, then look for an option called "Set as default" or "Default app." If you see it, tap it and confirm your choice. Some Android phones also let you change defaults by opening the app itself and looking in its settings menu.
If you have already set a default and want to change it, you may need to clear the old default first. Go back to Settings, find "Apps," search for the app that is currently the default, and look for a button that says "Clear defaults" or "Reset." Tap it, then set a new default the same way. This is especially common when you want to switch browsers or email apps — Android sometimes locks in your choice and makes it harder to change.
Why defaults matter and when to change them
Defaults matter because they shape how you use your device every day. If your default browser is slow or crashes often, you will have a frustrating experience every time you click a link. If your default printer is the office printer instead of your home printer, you might waste paper or print to the wrong place by accident. If your default email app does not work well with your email account, you will miss messages or have trouble sending them. Changing a default is usually free and takes less than a minute, so there is no reason to stick with something that does not work for you.
You should change a default if the automatic choice does not match how you actually work. If you prefer Firefox but your computer opens Chrome, change it. If you use Gmail but your phone opens Outlook, change it. If you have a home printer and a work printer, set the one you use most often as the default and manually choose the other one when you need it. Defaults are meant to save you time, not frustrate you. If a default is getting in your way, take thirty seconds to fix it.
Frequently Asked Questions
Can I have different defaults for different situations?
Not really — you can only set one default at a time. However, most devices let you override the default in the moment. When you click a link, you can usually hold down a button or right-click to choose a different browser. When you print, you can pick a different printer before you send the job. This gives you the speed of a default most of the time and the flexibility to change it when you need to.
What happens if I delete the program that is set as my default?
Your device will stop using it as the default and may pick a different program automatically, or it may ask you to choose one the next time you need it. You will not break anything by deleting a default program. If you want to use that program again later, you can reinstall it and set it as the default once more.
Why does my device keep asking me to set a default?
This usually happens when you install a new program that can do the same job as your current default — for example, installing a new browser when you already have one. Your device is asking which one you prefer. You can ignore the prompt and keep your current default, or tap the notification to change it. The prompt will stop appearing once you make a choice.
Can websites or apps change my defaults without asking?
Modern operating systems protect against this, but it used to happen. Windows, Mac, iPhone, and Android all now require you to manually change a default in Settings — a website or app cannot do it for you. If you notice a default has changed and you did not change it yourself, check your Settings to see what happened and switch it back.
Do I need to restart my device after changing a default?
No. Most defaults take effect immediately. The next time you click a link, open a file, or use that feature, your new default will be there. You do not need to restart your computer or phone.
