220-1102 Practice Question: Migrating from Windows 10 to Windows 11 on 50…
A company is migrating from Windows 10 to Windows 11 on 50 computers. After the upgrade, several users report that a critical line-of-business application no longer works. The application ran fine on Windows 10. You need to get it working without rolling back the entire OS. What is the most efficient solution?

Correct answer & explanation
✓
Reinstall the application on each computer in Windows 10 compatibility mode.
Windows 11 includes a Windows 10 compatibility mode that can be applied to individual applications. Using the Application Compatibility Toolkit (ACT) or the built-in compatibility troubleshooter to set the application to run in Windows 10 compatibility mode is the most efficient fix, as it does not require a full OS rollback.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Roll back all 50 computers to Windows 10 using the recovery partition.
Why it's wrong here
Rolling back all 50 computers to Windows 10 using a recovery partition is an extremely time-consuming and disruptive process, potentially taking many hours per machine. Furthermore, a recovery partition typically restores the *current* OS to a clean state, not a previous OS version after an upgrade, unless a specific 'Go back' option is available within the 10-day post-upgrade window. This approach also forfeits all the potential security and feature benefits of the Windows 11 migration.
- ✓
Reinstall the application on each computer in Windows 10 compatibility mode.
Why this is correct
Reinstalling the application and configuring it to run in Windows 10 compatibility mode is the most efficient and least disruptive solution. This built-in Windows feature uses compatibility shims to emulate the environment of an older operating system, often resolving minor API calls or system behavior differences that cause issues. It allows the company to retain the benefits of Windows 11 while addressing the specific application's needs without a full OS downgrade.
- ✗
Enable Hyper-V on each computer and run the application in a Windows 10 virtual machine.
Why it's wrong here
Hyper-V requires hardware virtualisation support and a Windows 11 Pro or Enterprise edition, yet many of the 50 computers may run Windows 11 Home, which lacks Hyper-V entirely, making this solution impossible to deploy uniformly. It is tempting because running a legacy application in a virtualised Windows 10 environment is a standard compatibility tactic when the OS itself cannot be downgraded, and it would be correct if all machines had Pro/Enterprise and the application could not be fixed via compatibility settings or shims.
- ✗
Use the Windows 11 'Reset this PC' feature to reinstall Windows 11 and then reinstall the application.
Why it's wrong here
Using the 'Reset this PC' feature would reinstall Windows 11, effectively returning the operating system to a clean state, but it would not address the underlying application compatibility issue with Windows 11 itself. This feature is designed to fix OS corruption or performance problems, not to provide an older operating system environment for legacy applications. After a reset, the application would likely still encounter the same compatibility failures when reinstalled on the fresh Windows 11 instance.
