We’ve all done it: a phone, tablet, or computer announces that an update is ready, and we select “Remind Me Later.” While postponing an update occasionally isn’t a big deal, regularly ignoring them can leave your device less secure and more difficult to use.

Software updates aren’t only about adding new features. Many contain important security fixes that repair weaknesses discovered after the software was released. Installing these updates helps protect your device from criminals who may try to take advantage of those vulnerabilities.

Updates can also fix frustrating problems. If an app suddenly freezes, your battery seems to drain unusually quickly, or a feature isn’t working properly, an available update may contain a solution. Updates can sometimes improve performance and compatibility with other apps and devices as well.

Fortunately, you don’t have to remember to check constantly. Most smartphones, tablets, and computers offer automatic updates. Look under your device’s Settings menu for options such as “Software Update,” “System Update,” or “Windows Update.” You can usually choose to have important updates downloaded and installed automatically.

Before installing a major update, make sure your device is charged or plugged in and, when appropriate, connected to Wi-Fi. Keeping important files backed up is also a good general precaution.

One warning: scammers sometimes send fake messages telling you to click a link to “update” your device. Don’t use unexpected links. Instead, check for updates directly through your device’s settings or official app store.

Those update reminders may be inconvenient, but keeping your technology current is one of the simplest ways to help it stay secure and work properly.
