220-1102 Operating Systems Practice Question
A technician needs to upgrade a computer from Windows 10 Home to Windows 10 Pro. The current installation is activated with a digital license. Which of the following is the MOST efficient method to perform this upgrade while preserving user data and installed applications?
⚠ Common exam trap
It's easy for candidates to assume a clean installation or media creation is required for edition upgrades, not realizing that entering a product key directly triggers the same in-place upgrade mechanism without extra steps.
Answer choices
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
✓
Enter a Windows 10 Pro product key in the Settings > Update & Security > Activation page
Entering a Windows 10 Pro product key in Settings > Update & Security > Activation triggers an in-place feature upgrade that preserves all user data, settings, and installed applications. This is the most efficient method as it requires no external media, no reinstallation, and leverages the existing digital license to seamlessly transition from Home to Pro.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Perform a clean installation of Windows 10 Pro using installation media
Why it's wrong here
Performing a clean installation of Windows 10 Pro wipes the boot partition, permanently deleting existing user profiles, installed applications, and any data stored on the system drive. While you could back up files and reinstall apps, this defeats the 'preserve everything' requirement and carries the risk of forgetting critical data. The clean-install path is appropriate for replacing the OS with a fresh copy, but not for a simple Home-to-Pro edition upgrade because Windows fully supports a non-destructive in-place upgrade.
- ✓
Enter a Windows 10 Pro product key in the Settings > Update & Security > Activation page
Why this is correct
Entering a valid Windows 10 Pro product key in Settings > Update & Security > Activation triggers the supported in-place edition upgrade. The operating system contacts Microsoft's activation servers, verifies the key's validity, and then automatically installs the Pro edition components on top of the current Home installation. This method preserves all personal files, installed desktop applications, settings, and user accounts, making it the quickest and most streamlined approach. No installation media, ISO file, or bootable USB is required, which is why it is the textbook answer for this scenario.
- ✗
Use the Media Creation Tool to create a bootable USB and select 'Upgrade this PC now'
Why it's wrong here
The Media Creation Tool offers an 'Upgrade this PC now' option that can perform a valid in-place upgrade, but it requires downloading a complete Windows 10 ISO first, even though only the edition-specific components are needed. After the large download, the tool launches Windows Setup and walks through a user-interface-driven installation process, which is time-consuming and needlessly complex. Unlike the direct product-key method, the setup program also asks configuration questions and can potentially stall on Windows Update or driver checks. Ultimately, this approach works but is an over-engineered substitute for a single product key entry.
- ✗
Purchase and download a Windows 10 Pro ISO from Microsoft and run setup.exe
Why it's wrong here
Downloading a Windows 10 Pro ISO from Microsoft and manually running setup.exe is the most labor-intensive path, as you must select the correct edition, language, and architecture, then mount the disk image and launch setup. The setup process requires choosing between upgrade or custom install options and explicitly confirming 'Keep personal files and apps,' leaving room for user error that could result in data loss. While it technically accomplishes the same in-place edition upgrade, it duplicates the functionality already available in the Activation page and introduces unnecessary manual steps. This method is typically used for offline or bulk deployments, not for a single desktop needing a quick Home-to-Pro conversion.

Same concept, more angles
1 more way this is tested on 220-1102
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. 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?
easy- A.Install the Domain Join feature via Windows Features
- ✓ B.Insert a product key for Windows 10 Pro in the Settings app
- C.Use the Windows 10 Installation Assistant to install the Enterprise edition
- D.Reinstall Windows 10 from a Pro installation media and choose 'Keep nothing'
Why B: 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.
