Setting Up a New Office Computer: A Checklist for Small Businesses

A new computer is a good moment to get things right. The way a work computer is set up on day one decides how secure it is, how easily it can be replaced if it is lost, and how much time staff will waste fighting it later. Yet many small businesses unpack the laptop, click through the setup screens as quickly as possible and hand it over.

This checklist covers what to do between unboxing a new Windows computer and giving it to a staff member. Most of it takes an hour or two, and you can reuse the same list for every new machine.

Before you start

• Check the hardware against what you ordered. Confirm the processor, memory (RAM) and storage in Settings, under System and then About. For normal office work, 8 GB of RAM is the minimum and 16 GB is more comfortable, and an SSD rather than a traditional hard drive makes a large difference to speed.
• Keep the box, receipt and warranty details together, and record the serial number in a simple list of company equipment.
• Connect to a reliable internet connection and power. The first setup downloads a lot of updates.

1. Create the right accounts

Decide in advance who will own the computer's accounts. Two common mistakes cause problems later: setting up the computer with a staff member's personal email, and having everyone use one shared admin account.

• If your business uses Microsoft 365 Business, sign in with the staff member's work account during setup. Depending on your plan, this can connect the computer to your organisation's management and security settings.
• Otherwise, create a separate administrator account that the business controls, with a strong password stored safely, and a standard user account for the staff member for everyday work.
• Do not use a staff member's personal Microsoft or Google account as the main account on a company computer. If they leave, getting access back can be difficult.

Working day to day in a standard account, rather than an administrator account, means that much malicious software cannot install itself without asking for the admin password.

2. Install all updates

A new computer may have sat in a warehouse for months, so it is rarely up to date. Open Settings, Windows Update and install everything available, restarting as often as needed until no more updates appear. Also check for driver and firmware updates, often through the manufacturer's own update app.

Then make sure automatic updates stay on. Updates fix security holes that attackers actively use, and skipping them is one of the most common reasons small business computers get compromised.

3. Remove software you do not need

Many new computers come with trial antivirus programs, games and manufacturer utilities. Some are useful; many just slow the computer down and show pop-ups.

• Open Settings, Apps, Installed apps and uninstall trials, games and anything you do not recognise as necessary.
• Keep the manufacturer's update or support tool if it handles drivers and firmware.
• If a trial antivirus is installed and you do not plan to pay for it, uninstall it so the built-in Microsoft Defender can take over properly. Two antivirus programs running together can cause problems.

If a computer is heavily loaded with unwanted software, or you are reusing an older machine, a clean installation can be quicker. Our guide to installing Windows 11 from a bootable USB explains how.

4. Set up security

• Antivirus: check that Windows Security shows green ticks for virus and threat protection, firewall and app protection.
• Device encryption: turn on BitLocker or Device Encryption (in Settings, Privacy and security). If the laptop is stolen, the data on the drive cannot be read without the account password. Make sure the recovery key is saved to the business's Microsoft account or stored somewhere safe, not only on the laptop.
• Sign-in: set a strong password or PIN, and use Windows Hello fingerprint or face sign-in if the computer supports it.
• Screen lock: set the screen to lock automatically after a few minutes of inactivity.
• Find my device: turn it on so a lost laptop can be located and locked.

Our small business cybersecurity checklist covers the wider habits around these settings, such as two-step verification and phishing.

5. Set up backups and file storage

Decide where work files will live before the staff member starts saving anything. The usual choice is OneDrive or Google Drive, so files are available on other devices and survive a lost or broken computer.

• Sign in to the cloud storage app with the work account.
• On Windows with OneDrive, turn on folder backup for Desktop, Documents and Pictures.
• If you also use external drive backups, set up File History now.

Our guide to backing up business files explains how to combine these into a reliable plan.

6. Install business software

Make a standard list of the software every computer needs, so setups are consistent. A typical list includes:

• Office apps: Microsoft 365 or Google Workspace.
• A modern browser, signed in with the work account so bookmarks and saved passwords follow the user.
• A password manager.
• A PDF reader.
• Your accounting, point-of-sale or industry-specific software.
• Communication tools such as Teams, Zoom or WhatsApp Desktop.
• Remote support software, if your IT provider uses it.

Only download software from the official website or the Microsoft Store. Cracked or "activated" copies from unofficial sites are a very common source of malware and put the whole business at risk.

7. Connect printers and shared resources

• Add the office printers and scanners, then print a test page.
• Connect to shared folders or Teams and SharePoint sites the person needs.
• Connect to the staff Wi-Fi network, not the guest network.
• Set the correct time zone, language and keyboard layout, especially if staff use French and English keyboards.

8. Record and hand over

Before handing the computer over, record the details in your equipment list:

• Make, model and serial number.
• Who it is assigned to and the date.
• Purchase date and warranty end date.
• Where the encryption recovery key is stored.

Then spend fifteen minutes with the staff member: show them where to save files, how to sign in to the password manager, how updates work and who to contact if something goes wrong. A short explanation now prevents many problems later.

When someone leaves

The same list works in reverse. When a staff member leaves, make sure their files are in the business's cloud storage, remove their access to work accounts, reset the computer and only then give it to someone else. If you set up accounts properly in step 1, this takes minutes rather than days.
