Key Takeaways
- Installing system updates immediately after first boot closes critical security gaps.
- Creating a backup strategy on day one protects your data before anything goes wrong.
- Removing bloatware and configuring privacy settings improves performance and security.
- Setting up a password manager and two-factor authentication from the start builds lasting security habits.
- Migrating files and bookmarks early prevents relying on an old machine longer than necessary.

Why the First Few Hours Matter
Unboxing a new computer feels exciting — but the decisions you make in the first few hours shape how well that machine serves you for years. A rushed setup often means missing updates, weak passwords, no backups, and a cluttered system from day one. A structured approach takes a little longer but pays dividends immediately.
If you haven't yet chosen between a desktop and a laptop, our guide to matching a computer to how you actually work covers that decision in detail. And if this is your first PC altogether, everything a first-time PC owner needs to know before day one is worth reading alongside this checklist.
Use the checklist below as your literal to-do list. Work through it top to bottom, and check items off as you go.

Tools and Resources You'll Want Ready
Before you begin, gather the items below. Having them at hand prevents interruptions mid-setup.
External hard drive or SSD
Used to transfer files from your old computer and to store a local backup of your new system.
Password manager
Stores and generates strong, unique passwords for every account you set up during configuration.
Cloud storage account
Provides an offsite backup location and makes files accessible across multiple devices.
USB flash drive
Useful for transferring small files or holding a bootable recovery tool if your OS supports it.
Your old computer or device
Needed to export bookmarks, transfer files, and retrieve software licence keys before migrating.
Common Pitfalls to Avoid
Even technically confident users trip over a handful of predictable mistakes during a new computer setup. The two most consequential ones are worth calling out explicitly.
Don't Skip Updates Before Installing Software
Installing applications before running system updates is a common shortcut that creates real security exposure. Many updates patch vulnerabilities that can be exploited by malicious software — meaning apps you install on an unpatched system may operate in an insecure environment from the start. Always complete the full update cycle, including a restart, before adding any third-party software.
Set Up Backups Before You Need Them
A backup system only protects data that existed before something went wrong. Hardware failures, ransomware, and accidental deletions can happen at any time — including during the first week of use. Configure your backup solution on day one, even if your new machine currently holds nothing of value, so the habit and infrastructure are already in place when important files start accumulating.
Once your machine is fully configured, the work doesn't stop there. Building consistent maintenance habits — regular updates, storage hygiene, and proper cooling practices — is what keeps a computer running well over time. Our guide to computer maintenance habits worth building picks up exactly where this checklist leaves off.
If you're also moving data from a smartphone, the process has its own set of steps. See our walkthrough for transferring data to a new phone for a comparable structured approach on mobile devices.
Bloatware Removal: Proceed Carefully
When removing pre-installed software, be cautious about uninstalling anything you don't recognise before researching it. Some system utilities have non-obvious names and are required for hardware features like touchpad gestures, battery management, or fingerprint readers. A quick search on the manufacturer's support site can confirm whether an application is safe to remove.
