Why the First Hour Matters Most

Unboxing a new computer is exciting — but what you do in the first hour shapes how well that machine serves you for years. Skipping setup basics doesn't just leave loose ends; it can expose your data, slow down performance, and create headaches when something goes wrong later.

This checklist walks you through every meaningful step before you settle in and start using your new laptop or desktop for real. If you haven't yet decided between a laptop and a desktop, our guide to choosing between the two can help you think it through. And for a broader foundation on computers, the complete buyer's education is a solid starting point.

Work through the groups below in order — each one builds on the last.

Before You Power On

Locate your proof of purchase and register the device with the manufacturer to activate your warranty coverage. Must
Identify which operating system version came pre-installed so you know exactly what you're starting with. Must
Check the box contents against the listed accessories — power adapter, cables, and any included documentation. Should

Account & Sign-In Setup

Create a local user account with a strong, unique password rather than relying solely on a manufacturer default. Must
Set up or sign into your operating system account (Microsoft account, Apple ID, or Google account) only on a secured network. Must
Enable two-factor authentication (2FA) on your primary account — this adds a second verification step that significantly reduces unauthorized access. Must
Configure a PIN or biometric login (fingerprint or face recognition) for faster, secure everyday access. Should

System Updates & Security

Run the operating system's full update process immediately — new computers often ship with months-old software. Must
Update firmware or drivers for key hardware components like graphics, network adapter, and audio. Must
Confirm the built-in security software (Windows Defender, macOS Gatekeeper, etc.) is active and up to date. Must
Review and adjust your firewall settings to ensure it's turned on by default. Should

Removing Bloatware

Open the list of installed programs and uninstall any pre-loaded software you don't recognize or need. Should
Disable startup programs that launch automatically — only keep the ones you actually use daily. Should
Check browser extensions pre-installed on any bundled web browser and remove unfamiliar ones. Nice to have

Backup Configuration

Set up automatic cloud backup for your documents folder, photos, and desktop files before storing anything important. Must
Connect an external drive and configure the operating system's built-in backup tool (Time Machine on macOS, Backup and Restore on Windows). Should
Do a test backup and verify the files are actually recoverable from your backup destination. Should

Privacy & Preferences

Review your operating system's privacy settings and turn off data-sharing options you're not comfortable with. Must
Set your screen timeout and lock-screen behavior so the device locks automatically when unattended. Must
Adjust display resolution, text size, and audio levels to comfortable defaults for your environment. Nice to have
Install a reputable password manager to store your credentials securely rather than saving them in your browser. Nice to have

Tools You'll Want Nearby

Before you start, gather a few things so you're not hunting for them mid-setup. None of these require a tech background to use — they're straightforward utilities and habits that make the process smoother.

Required

External hard drive or SSD

Used to configure a local backup so your files are protected against hardware failure from the start.

Required

Cloud storage account

Provides automatic off-site backup for documents and photos without relying on physical media.

Optional

Password manager app

Stores all your login credentials in one encrypted vault, removing the need to reuse weak passwords.

Required

Authenticator app (for 2FA)

Generates time-sensitive verification codes for two-factor authentication on your accounts.

Required

Wired Ethernet connection or stable Wi-Fi

Needed to download system updates reliably — a dropped connection mid-update can cause problems.

Don't Skip Updates on Public Wi-Fi

Downloading system updates on an open public network (coffee shops, airports, hotels) exposes your unpatched machine to risk before it's secured. Complete your initial update process on a trusted home or private network. If that's not possible, use a mobile hotspot as a safer alternative.

Once your machine is secure and backed up, the next logical step is moving your old files over. Our guide on transferring files and settings to a new computer walks through that process clearly. And if you're planning to add smart home devices to your setup, check what to verify before adding another smart device first.

To keep your machine running well long after today, build the habits covered in our article on keeping your laptop running well for years.

Back Up Before You Do Anything Else Productive

Hardware can fail at any time — including on a brand-new device. Until a backup is configured and verified, every file you create exists in only one place. Don't store important documents, photos, or work files on your new machine until your backup system is tested and running. A backup you've never tested is not a backup.
