How to Update Your Computer Safely

Software updates fix security holes, improve stability and add features. Ignoring them leaves your computer exposed to attacks that are already known. The steps below help you update safely, so the process does not interrupt your work or cause problems.

Why updates matter

Criminals study released updates and use the flaws they fix against people who have not installed them. Installing security updates is one of the simplest protections you have. Feature updates are less urgent, but they still bring fixes that matter over time.

Update Windows

Open Settings, then Windows Update.
Select Check for updates and install any that are available.
Choose Advanced options to set active hours, so Windows does not restart during the times you use the computer.
Restart when it is convenient, and save your work first.

Update macOS

Open System Settings, then General, then Software Update. Install available updates. Check first that your important apps support the new version, especially work software.

Update apps and drivers

Turn on automatic updates in your browser and major apps.
For graphics cards, update drivers from the manufacturer's website, not from random driver sites.
Check the motherboard or laptop maker's support page for chipset and Wi-Fi drivers.

Before a big update

Make a backup of your important files. See how to back up your computer.
Check that the computer has enough free space and is plugged in.
Read the release notes for anything that affects work or hardware you use.

If an update causes a problem

Restart the computer first. On Windows, you can uninstall a recent update from Settings, under Windows Update, then Update history. On Mac, restore from a Time Machine backup if the problem is serious. Search the manufacturer's support pages for known issues, and report the problem so it can be fixed.

Frequently asked questions

Should I wait a few days before installing updates?

For major feature updates, waiting a week or two lets others find early problems. Security updates should be installed sooner.

Are third-party updater tools safe?

Some are, but they can install unwanted software. Use the updates built into the system and the app itself where possible.

Use a restore point or backup first

Windows can create a restore point before major changes, and macOS can make a snapshot through Time Machine. Create one before big updates so you can go back if something breaks. Restore points do not replace a full backup, but they are a useful safety net for system-level problems.

Update your router and phone too

Computers are only one part of a home network. Routers, printers and phones also receive security updates. Check each device's settings once a month, and set them to update automatically when the manufacturer allows it. Old devices on your network are a common route for attackers.
