How to Fix Microsoft 365 Licensing and Activation on Shared Computers

Product: Microsoft 365
Device & OS: not provided
Scenario: Multiple employees are sharing a single workstation and signing into Windows with their own distinct user profiles.
Observed behavior: Users experience repeated prompts for license validation and activation whenever they switch accounts or open Office applications on the shared computer.

Before you start

Verify your current Microsoft 365 subscription plan, as Shared Computer Activation requires specific licenses such as Microsoft 365 Business Premium or Enterprise E3/E5.

Enable Shared Computer Activation via Registry Editor

Configure Windows to use a licensing mode specifically designed for multiple users, preventing repeated activation prompts.

Shared Computer Activation allows multiple users to access Microsoft 365 Apps on a single machine without counting against their individual device limits. This is ideal for shift workers or shared terminal environments.

Open Registry Editor

Press the Windows key + R to open the Run dialog. Type 'regedit' and press Enter to launch the Registry Editor.

Navigate to the Office Configuration Key

Go to the following path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\ClickToRun\Configuration.

Add the Shared Computer Licensing Value

Right-click in the right pane, select New > String Value. Name it 'SharedComputerLicensing'.

Modify the Value Data

Double-click 'SharedComputerLicensing' and set its Value data to '1'. Click OK and restart the computer.

Frequently Asked Questions

Does Shared Computer Activation require an extra Microsoft subscription?

No, it does not require a separate subscription, but it does require a qualifying Microsoft 365 plan. Plans like Microsoft 365 Business Premium, Enterprise E3, or E5 include this feature natively.

Why does Microsoft 365 ask for activation every time a new user logs in?

By default, Office licenses are tied to individual users and their specific device limits. When a new user logs into a standard installation, Office attempts to verify their individual license, causing repeated prompts on shared devices.

Can small businesses use a single Microsoft 365 license for multiple employees?

A single license is intended for one user. To share a computer legally without Shared Computer Activation, you either need a shared Windows account activated with that single license, or you must rely on the free Office for the web.

What happens if our subscription plan doesn't support Shared Computer Activation?

If your plan doesn't support it, users can access Office for the web using their basic Microsoft accounts, you can assign a shared generic Windows account, or you may need to upgrade your subscription to a premium tier.
