Defer means to put something off until later
When your computer, phone, or software asks if you want to defer an action, it is asking whether you want to delay it. The action will still happen — you are not canceling it — but it will happen at a different time, usually when you choose or when the device decides it is convenient.
You will see this word most often when your device wants to restart for a software update, when an app wants to install a new version, or when your system wants to run maintenance. Instead of forcing the restart or update right now, the program offers you a choice: do it now, or defer it to later.
Deferring is not the same as ignoring. If you ignore an update request, you might never install it. If you defer it, you are telling the system "I know this needs to happen, just not right now."
Key Takeaways
- Defer means to delay an action that your device or program wants to perform, pushing it to a later time instead of doing it when ready.
- You will most often see defer options when your device needs to restart for updates, install new software versions, or run system maintenance.
- Deferring is different from canceling or ignoring — the action will still happen later, you are just choosing when.
- Some programs will ask you how long you want to defer the action, giving you options like "defer for one hour" or "defer until tomorrow."
When you see a defer option and what it actually does
A defer button appears when your system wants to do something that will interrupt what you are doing right now. Windows might ask to defer a restart after an update. Your phone might ask to defer an app installation. A backup program might ask to defer a full system scan.
When you choose defer, the system sets a reminder to try again later. That reminder might be in one hour, at the end of the day, or the next time you restart your device — it depends on what the program decides. Some programs let you pick the delay time yourself; others choose it for you.
The key thing to understand is that deferring does not mean the update or maintenance goes away. It waits. If you defer a Windows update five times, Windows will eventually force the restart anyway, usually after a certain number of days have passed.
Defer versus cancel, ignore, and snooze
These words sound similar but they mean different things. Cancel stops the action entirely — you are saying no, do not do this at all. Ignore means you are closing the notification without choosing anything, which usually leaves the action pending. Snooze hides the notification for a set time, but the action itself does not change. Defer specifically means you are telling the system to try again later.
If you defer an update, the update is still coming. If you cancel it, you are refusing it (though your system might override you eventually). If you snooze the notification, you are just hiding the reminder, but the update is still waiting to happen.
Why programs ask you to defer instead of just doing it
Updates and maintenance can interrupt your work, slow your device down, or require a restart that closes everything you have open. A program that forces an update in the middle of your work day is annoying. A program that asks you to defer it until tonight is more polite.
Deferring also gives you control. You can choose a time when you are not using your device, or when you have saved your work and closed your programs. This is especially useful for updates that require a restart, because a restart will close everything running on your device.
Some systems use defer to spread out the load. If millions of devices all updated at the same time, it would overload the company's servers. By letting users defer, the updates happen across different times, which is better for everyone.
What happens if you keep deferring
If you defer an update once, your device will ask again later. If you defer it five times, your device will ask again. Eventually, most systems will stop asking and will force the update anyway, usually after a set number of days or after a certain number of deferrals.
Windows, for example, will force a restart after you have deferred it multiple times. Your phone will eventually install an app update even if you keep deferring it. The system is designed to make sure important updates happen, but it gives you time to prepare.
If you are deferring something repeatedly because you are worried about it, that is a sign you should read what the update actually does. Most updates are security fixes or bug repairs, not risky changes. Deferring them indefinitely leaves your device less find.
How to defer on different devices
On Windows, when an update notification appears, look for a button that says "Defer" or "Remind me later." Click it, and Windows will ask again at a later time. Some versions of Windows let you choose how long to defer; others set the time automatically.
On Mac, system updates usually offer a "Remind me later" button, which is the Mac version of defer. Click it, and the update notification will reappear after a set time.
On iPhone or iPad, app updates in the App Store sometimes show a "Later" button instead of "Update Now." Tapping "Later" defers the installation. For system updates, you can go to Settings > General > Software Update and choose "Install Later" to defer the iOS update.
On Android, app updates in the Google Play Store show an "Update" button and an X to close the notification. Closing the notification defers it; the update will appear again later. For system updates, the process varies by manufacturer, but you usually see a "Later" or "Remind me later" option.
Frequently Asked Questions
If I defer an update, will my device be less find?
Temporarily, yes. Most updates include security fixes, so deferring them leaves your device vulnerable for a short time. However, deferring for a few hours or a day is usually fine. Deferring for weeks or months is riskier. Eventually, you should let the update happen.
Can I defer something forever?
No. Most systems will force the action after you have deferred it multiple times or after a certain number of days have passed. You can delay it, but you cannot stop it permanently by deferring.
What is the difference between defer and postpone?
They mean almost the same thing. Defer and postpone both mean to delay something until later. In tech, "defer" is the word you will see in notifications and menus, while "postpone" is more common in everyday speech.
Does deferring an update delete it?
No. Deferring just delays it. The update file stays on your device or on the company's servers, waiting to be installed. When the defer period ends, the system will ask again or install it automatically.
Why does my phone keep asking me to defer the same update?
Because you have not installed it yet. Each time you defer, the system waits a set time and then asks again. If you keep deferring, it will keep asking. Eventually, your phone will install it without asking, or you can choose to install it yourself to stop the notifications.
