Quick Answer
Open HP Support Assistant on your new HP laptop to finish device registration and check for updates. Then go to microsoft365.com/setup, sign in with your Microsoft account, and follow the prompts to download and install the apps. On an HP OmniBook 5 or HP EliteBook, the whole process takes only a few minutes, and Word, Excel, Outlook, Teams, and OneDrive are ready to use right away.
Introduction
Your new HP laptop is out of the box and Windows is set up. The next step is getting Microsoft 365 running so Word, Excel, Outlook, Teams, and OneDrive are all ready when you need them.
This guide walks you through activating and setting up Microsoft 365 from day one, using HP Support Assistant to handle the device side and microsoft365.com/setup to handle the rest. HP OmniBook and HP EliteBook laptops come with HP Support Assistant already installed, so that is your first stop for registration and setup guidance.
Step 1: Start With HP Support Assistant
Before you install anything else, open HP Support Assistant. We pre-install it on HP OmniBook and HP EliteBook laptops to make setup as simple as possible, and it is the smartest first stop after Windows is up and running. You will usually find it pinned to the taskbar, or you can search for it from the Start menu.
At first launch, HP Support Assistant checks your laptop for the latest driver and firmware updates, which keeps everything from Wi-Fi to battery performance running smoothly. From the My Dashboard tab, you can see your device and apply any available updates in a couple of clicks. You can set updates to install automatically or to simply notify you when they are ready.
This is also where you register your HP laptop, which activates your warranty coverage and connects the device to our support system. With that done, you are ready to bring Microsoft 365 on board.
Step 2: Activate Microsoft 365
With your device set up, it is time to get Microsoft 365 running. How you start depends on whether your subscription came with your laptop or you are adding it yourself.
If Microsoft 365 is included with your HP laptop
Some HP laptops come with a Microsoft 365 trial or subscription. If yours does, you will find a product key or redemption link in the box, or HP Support Assistant may point you to it.
To activate, go to microsoft365.com/setup, sign in with your Microsoft account, and enter the product key if prompted. If you do not have a Microsoft account yet, you can create one for free at microsoft.com. From there, follow the prompts to download and install the apps.
If you are adding Microsoft 365 to your HP laptop
If your laptop did not come with Microsoft 365, you can add it in a few minutes. Visit microsoft.com to compare plans and choose the one that fits how you work. For help deciding, see our guide: Microsoft 365 Personal vs. Family vs. Business.
Once you have subscribed, head to microsoft365.com/setup, sign in with that same Microsoft account, and follow the steps to download and install.
Step 3: Sign In and Sync Your Microsoft Account
Once Microsoft 365 is installed, sign in to each app with your Microsoft account. Outlook, Teams, OneDrive, and Word all use the same account, so one sign-in connects everything.
Signing in also starts OneDrive. It begins syncing files from your cloud storage to your new HP laptop, so your existing documents, photos, and folders show up automatically. You will see a OneDrive cloud icon in the taskbar, and the sync status appears right next to your files in File Explorer.
If you are upgrading from an older laptop, this is the fastest way to pick up where you left off. Anything you kept in OneDrive on your old device appears on your new HP laptop as soon as you sign in, so manual transfer is not needed.
Step 4: First Apps to Open and Configure
Microsoft 365 is installed and you are signed in. Here are the four apps to open first to get productive on day one.
Outlook: set up your email
Outlook is where most people start. Add your email account - whether it is a Microsoft address or another provider - then confirm your calendar synced and turn on Focused Inbox to keep your most important mail up top.
On an HP EliteBook, the high-resolution display and long battery life mean you can keep email open and readable all day.
Teams: connect with your team
Open Teams and it signs you in automatically with the same Microsoft account. If your organization uses Teams, your chats, channels, and calendar are right there waiting. For a deeper look at what Teams can do, see our guide: How to Use Microsoft Teams: Channels, File Sharing, and Project Collaboration.
OneDrive: confirm your files are syncing
Check the OneDrive icon in the taskbar. A cloud icon means a file lives online only. A green check means it is also saved on your laptop. Spinning arrows mean a sync is in progress. Once it settles, your files are ready in File Explorer.
Word, Excel, and PowerPoint: ready to use
These are installed and need no additional setup. Open Word and start a blank document to confirm everything is working. If your plan includes Copilot, you will see it on the Home tab in the ribbon.
Plans vary, so check microsoft.com for what is included with yours.
Getting More From Microsoft 365 on Your HP Laptop
You are set up, so here is where to go next. Open HP Support Assistant now and then to keep drivers and software current, which keeps your laptop running at its best.
To get more from the suite itself, our related guides below break down what each app does. And if your plan includes it, Microsoft Copilot works right inside Word, Excel, PowerPoint, Outlook, and Teams to help you draft, summarize, and analyze faster.
Get the most from Copilot with the right hardware
AI-powered features like Microsoft Copilot perform best on laptops with dedicated neural processing units (NPUs). HP Copilot+ PCs are built with NPUs that accelerate AI tasks locally on the device, delivering faster Copilot responses in Word, Excel, Teams, and Outlook. If your Microsoft 365 plan includes Copilot - or you plan to add it - an HP laptop with an NPU helps you get the most value from AI-assisted productivity from day one.
