220-1102 Operating Systems Practice Question
A user has a Windows 10 Home edition computer and needs to join it to a corporate domain. Which method can be used to upgrade to a domain-joinable edition?
⚠ Common exam trap
Many exam-takers confuse the ability to add a 'feature' via Windows Features with edition-specific capabilities, or they assume a clean install is the only way to change editions, overlooking the in-place product key upgrade method.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Insert a product key for Windows 10 Pro in the Settings app
Windows 10 Home edition lacks the domain join capability, which is available in Windows 10 Pro, Enterprise, or Education editions. Inserting a valid Windows 10 Pro product key via Settings > Update & Security > Activation triggers an edition upgrade that installs the necessary components (e.g., the Netlogon service and domain join UI) without requiring a full reinstallation. This is the only supported in-place upgrade path from Home to a domain-joinable edition.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Install the Domain Join feature via Windows Features
Why it's wrong here
The 'Domain Join' capability is not listed as an optional Windows feature in the 'Turn Windows features on or off' dialog, nor can it be added via DISM or PowerShell without changing the edition. Windows 10 Home is deliberately restricted from performing Active Directory domain joins; this functionality is unlocked only by upgrading to a Pro or Enterprise edition. Attempting to install it as a feature fails because the license layer and core configuration for domain membership are absent in Home.
- ✓
Insert a product key for Windows 10 Pro in the Settings app
Why this is correct
Navigate to Settings > Update & Security > Activation and select 'Change product key' to enter a legitimate Windows 10 Pro key. This triggers an in-place edition upgrade that installs the Pro license and enables features such as Domain Join, BitLocker, and Remote Desktop, while preserving all installed applications and user files. After the required restart, the computer can join an Active Directory domain and receive Group Policy objects. This is the correct and least disruptive method.
- ✗
Use the Windows 10 Installation Assistant to install the Enterprise edition
Why it's wrong here
The Windows 10 Installation Assistant is a Microsoft tool for applying feature updates to the same edition of Windows 10, such as upgrading a Home installation to the latest Home release or a Pro installation to the latest Pro release. It does not support converting a Home device to an Enterprise edition because Enterprise is a volume-licensed product distributed only through the Volume Licensing Service Center or Microsoft 365 admin portal. Enterprise deployments rely on KMS or MAK activation keys, not consumer product keys, and would require the device to be reimaged with Enterprise media and activated via a volume license agreement.
- ✗
Reinstall Windows 10 from a Pro installation media and choose 'Keep nothing'
Why it's wrong here
Reinstalling Windows 10 Pro with 'Keep nothing' performs a clean installation, completely wiping all user data, applications, and settings from the computer. While this method would indeed result in a domain-joinable Pro edition, it is not an *upgrade* path as it necessitates a complete system reset rather than preserving the existing user environment. This option is tempting because it delivers the required Pro edition. It would be the correct choice if a fresh, clean installation of Windows 10 Pro was desired, perhaps to resolve deep system issues or start anew, and data preservation was not a concern.
