Install Microsoft 365 on the New PC and Deactivate the Old One
The most straightforward method to move your Microsoft 365 subscription is to install it directly from your Microsoft account dashboard on the new computer, then remove the old software.
Microsoft 365 allows you to install the software on up to five devices simultaneously per user. You do not necessarily have to uninstall it from your old computer first to activate it on the new one. However, uninstalling it from the old device is highly recommended if you plan to sell, recycle, or give away the old computer.
On your new computer, go to Settings > Apps > Installed apps. Look for any preinstalled version like 'Microsoft 365 Family Trial' or 'Office 365' and select Uninstall. This prevents conflicts when you activate your actual subscription.
Open a web browser on your new computer, visit https://www.office.com, and sign in using the email address and password associated with your Microsoft 365 subscription.
Click the 'Install Office' or 'Install apps' button on the main dashboard. A setup file will download to your computer. Open this downloaded file and follow the on-screen instructions to complete the installation.
Once the installation finishes, open any application like Word or Excel. When prompted, sign in with your Microsoft account to successfully activate the software.
On your old computer, open the Control Panel, navigate to Programs > Programs and Features, select Microsoft 365 from the list, and click Uninstall to remove the software completely.
Try WPS Office for a Lightweight and Free Experience
If you are setting up a new computer and want to avoid complex subscription transfers, activation limits, or ongoing fees, WPS Office is an excellent alternative. It offers powerful tools for word processing, spreadsheets, and presentations in a single, lightweight application.
- 1. Download the installer: Visit the official WPS Office website and click the Free Download button.
- 2. Install the application: Run the downloaded installer on your new computer and follow the brief setup wizard.
- 3. Open and edit files immediately: Launch WPS Office to instantly open, edit, and save your existing Word, Excel, and PowerPoint documents without needing a subscription.
Frequently Asked Questions
Do I need my original product key to install Microsoft 365 on a new computer?
No, Microsoft 365 licenses are tied to your Microsoft account, not a physical product key. You only need to log in to your account at office.com to download and activate the software on a new device.
Will I lose my files when moving Microsoft 365 to a new computer?
Your locally saved files remain on your old computer and must be transferred manually via a USB flash drive, external hard drive, or local network. However, any documents you have saved to OneDrive will automatically sync and become available on your new computer once you sign in.
Why is my new computer saying my Microsoft 365 subscription is just a trial?
This commonly occurs because new computers frequently come with a preinstalled trial version of Microsoft 365. You should uninstall this preinstalled trial version from your settings and reinstall the software directly from your own Microsoft account dashboard.
Can I keep Microsoft 365 installed on both my old and new computers at the same time?
Yes. A standard Microsoft 365 Personal or Family subscription allows you to install the applications and remain signed in on up to five devices simultaneously using the same Microsoft account.
