In this guide, we explain how to install, activate, and configure Microsoft 365 on your computer from beginning to end.
Before installing Microsoft 365, make sure your computer meets the basic requirements.

For better performance and security, keep your operating system updated.
You need a Microsoft account to purchase, install, and activate Microsoft 365.
Go to the official Microsoft 365 website and sign in using your email address, phone number, or Skype account. If you do not have an account, create a new one.
Choose the Microsoft 365 plan that suits your needs. Available plans may include Personal, Family, Business, or organisation-based subscriptions.
If you already have a product key, enter it through your Microsoft account to activate the subscription.
After signing in, open the Microsoft 365 home page. From this dashboard, you can access online applications, recent documents, OneDrive files, account settings, and installation options.
On the Microsoft 365 home page, select the installation option and choose Install Microsoft 365 apps.
The installer file will begin downloading automatically. The downloaded file may appear as OfficeSetup.exe, Setup.Office.exe, or a similar name.
Open the downloaded installer file. Windows may display a User Account Control message asking whether you want to allow the application to make changes to your device.
Select Yes to continue.
The Microsoft 365 installer will download and install applications such as:
- Microsoft Word

- Microsoft PowerPoint
- Microsoft Outlook

The installation time depends on your internet speed and computer performance. Keep your computer connected to the internet during the process.
After installation, open the Windows Start menu and search for Word, Excel, PowerPoint, or another Microsoft 365 application.
Select the application to launch it.
When you open a Microsoft 365 application for the first time, you may be asked to sign in.

To confirm that Microsoft 365 is activated, open Word or Excel and follow these steps:

The page should display your Microsoft 365 subscription and show that the product is activated.

Depending on your subscription, you may be able to install Microsoft 365 on multiple computers, tablets, and mobile phones.

Microsoft 365 applications are available for Android and iOS devices.
