How to Set Up a New Computer in One Afternoon

A new computer should be set up carefully so it stays secure and tidy from the start. Setting it up takes an afternoon, and the steps below help you avoid the common mistakes of skipping updates, installing too much software and forgetting to back up.

Step 1: Connect and update

Connect to Wi-Fi and install all available updates before anything else. On Windows, use Windows Update. On Mac, use Software Update. Restart as needed. This closes known security gaps early.

Step 2: Create your account and password

Use a strong password for your main account, as explained in how to create strong passwords. Turn on the sign-in protection options the system offers, such as a PIN or fingerprint.

Step 3: Review privacy and security settings

Check which apps can use your location, camera and microphone.
Turn on the firewall and the built-in antivirus protection.
Turn on automatic updates for the operating system.

Step 4: Install only what you need

Install a browser, your office or study software, a password manager and any essential tools. Avoid adding many extra programs at once. Each one can start in the background and slow the computer.

Step 5: Set up backups

Turn on Windows Backup or Time Machine and connect an external drive. Turn on cloud storage for important folders. See how to back up your computer.

Step 6: Move your files

Copy your files from the old computer using a cable, an external drive or cloud storage. Check that important files open before you wipe the old machine. Sign in to your accounts and check that your bookmarks and passwords came across.

Step 7: Organise and customise

Set up your folders as described in how to organise files and folders. Pin the apps you use most to the taskbar or Dock, and adjust the display size and brightness.

Frequently asked questions

Should I set up a local account or use a cloud account?

A cloud account syncs settings and gives access to services. A local account keeps more privacy but offers fewer features. Either is fine if you protect the account with a strong password.

Do I need to install antivirus software?

Built-in protection is enough for most people when kept updated. Install a second product only if you have a specific reason.

Set up a second account for family

If several people share the computer, create a separate account for each person. This keeps files, browser profiles and settings apart, and it lets each user keep their own passwords. Use a standard account for children and everyday users, with an administrator account for installations.

Write down your setup

Keep a short note with your account names, the backup drive, important software licence keys and the Wi-Fi password. Store the note in your password manager rather than on paper near the computer. A clear record makes the next setup far quicker.
