A practical checklist covering the first steps to take when you get a new laptop — from updates to privacy settings.

Key Takeaways

Installing system updates immediately closes known security vulnerabilities before you go online.
Creating a strong, unique account password and enabling full-disk encryption protects data if the laptop is lost or stolen.
A password manager eliminates the need to reuse weak passwords across accounts.
Reviewing app permissions and privacy settings limits how much data your laptop shares by default.
Enabling automatic backups from day one ensures you never lose data you can't recover.

Why the First Hour Matters Most

Unboxing a new laptop feels like a fresh start — and it is. But that clean slate also means the device hasn't yet received a single security update, its privacy settings are calibrated for convenience rather than protection, and no backup system is in place. The decisions you make (or skip) in the first hour shape how exposed that laptop will be for years.

This checklist walks through the most important steps in plain language. You don't need technical expertise — just a bit of time and a methodical approach. If you're also setting up your home network for the first time, see our home Wi-Fi walkthrough before connecting the laptop to the internet.

First 10 Minutes: System Essentials

Run all available system updates immediately after connecting to Wi-Fi, before doing anything else. Must

Set a strong, unique login password for your user account — avoid names, birthdays, or dictionary words. Must

Enable full-disk encryption (BitLocker on Windows, FileVault on macOS) so your files are unreadable if the laptop is lost or stolen. Must

Create a separate standard (non-administrator) user account for everyday use, keeping the admin account reserved for software installs and system changes. Should

Account and Password Security

Set up a password manager and store your new laptop account credentials in it as your first entry. Must

Enable two-factor authentication (2FA) on your primary email account linked to this laptop — this is the account most likely to be targeted. Must

Sign in to your operating system account (Microsoft or Apple ID) only after setting up your password manager, so those credentials are captured securely. Should

Review and revoke access for any third-party apps already connected to your Microsoft or Apple account from a previous device. Nice to have

Privacy and Permissions

Open your system privacy settings and turn off location access for any apps that don't genuinely need it. Must

Disable diagnostic and usage data sharing unless you've made a deliberate choice to contribute it. Should

Review microphone and camera permissions, and block access for any application that has no clear reason to use them. Must

Turn off Bluetooth when you're not actively using it to reduce the device's exposure on public networks. Nice to have

Backup and Recovery

Configure an automatic backup solution — an external drive with Time Machine (macOS) or File History (Windows), or a cloud-based option — before adding personal files. Must

Verify the backup is working by checking that at least one test file has been successfully saved and can be restored. Must

Write down or securely store your encryption recovery key (BitLocker or FileVault), since losing it means losing access to all your data. Must

Set backup frequency to at least daily for any laptop used for work or important personal files. Should

Software and Browser Setup

Install a reputable browser and configure it to block third-party cookies and enable HTTPS-only mode by default. Should

Uninstall any pre-installed software (often called bloatware) that you don't recognize or plan to use, as unused apps can represent unnecessary security surface area. Nice to have

Tools You'll Want Nearby

Most of this checklist requires nothing more than the laptop itself and an internet connection. A few additional tools make certain steps easier or more robust.

Required

Password manager app

Generates and stores strong, unique passwords for every account so you never have to reuse or memorize them.

Optional

External hard drive

Provides a physical backup destination for Time Machine (macOS) or File History (Windows).

Required

Authenticator app (for 2FA)

Generates time-based one-time codes for two-factor authentication, more secure than SMS codes.

Optional

Cloud backup service

Offers an off-site backup copy of your files that survives hardware failure, theft, or fire.

If you share this laptop with family members, the account and permission steps below become even more important. Our guide on keeping accounts secure on a shared device covers the extra considerations worth knowing.

Save Your Encryption Recovery Key Now

Both BitLocker (Windows) and FileVault (macOS) generate a recovery key when you enable encryption. If you forget your login password or encounter a system error, this key is the only way to access your data. Store it somewhere completely separate from the laptop — printed and locked away, or saved in a password manager on a different device. Losing this key means your data is permanently inaccessible, with no override.

Ongoing Habits to Build From Day One

Running through this checklist once is a strong start, but laptop security is more of an ongoing practice than a one-time event. Set reminders to check for updates monthly, review which apps have been granted sensitive permissions every few months, and test that your backup is actually working by restoring a small file from it.

Don't Skip Updates Just to Get Started Faster

It's tempting to explore a new laptop before running updates, but the operating system shipped from the factory may be months behind on security patches. Known vulnerabilities are actively exploited by malicious software, and an unpatched system is at risk from the moment it connects to the internet. Let updates finish completely before signing in to accounts or downloading anything else.

For anything connected to your home network, pairing these laptop steps with broader network-level protections is worthwhile. Our article on home network security explains the practical steps that protect your connection and every device on it. And if you travel with your laptop, the same disciplined setup mindset applies — much like the pre-departure checklist travelers use before any trip.
