220-1102 Software Troubleshooting Practice Question

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
✓
B
Windows Update settings provides an option to view update history and uninstall specific updates. This allows the technician to remove the problematic cumulative update without affecting other system changes. System Restore would revert the entire system to a previous point, potentially removing other changes. System Configuration is for boot options, and Registry Editor is not a safe way to remove updates.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A
Why it's wrong here
System Restore is a recovery tool that reverts system files, registry settings, and some applications to a snapshot taken earlier. While it can remove a recently installed cumulative update, it also undoes any other changes—installed programs, driver updates, or system settings—made after that restore point. This broad, non-selective rollback is why it is not the appropriate targeted solution for removing a specific Windows 10 cumulative update.

B
Why this is correct
From Settings > Update & Security > Windows Update, clicking 'View update history' and then 'Uninstall updates' opens the Control Panel Installed Updates list, where Windows 10 cumulative updates are shown by their KB number. You can select the offending cumulative update and uninstall it, reverting only the files and registry entries belonging to that servicing package, without removing user data or separate applications. This is the supported, targeted method; technicians can alternatively use wusa.exe /uninstall from an elevated command prompt to remove the same update package.
- ✗
C
Why it's wrong here
System Configuration (msconfig.exe) primarily manages boot options, selective startup, and which services run at system startup. It has no capability to enumerate, disable, or remove Windows Update packages; its role is to troubleshoot boot and performance problems by toggling operating system services. Attempting to use msconfig to remove an update would either have no effect or, if you manually disable related Windows Update services, it could break future update checks and destabilize the servicing stack, making it an invalid choice.
- ✗
D
Why it's wrong here
Hand-editing the registry to remove a Windows update is unsupported and extremely risky, because updates are registered as packages within the Component-Based Servicing (CBS) store, not as simple standalone registry values. A single erroneous deletion can corrupt the component store, prevent future updates from installing, or even render Windows unbootable by breaking the servicing transaction. Microsoft's only safe, supported method for removing a cumulative update is through the Windows Update settings interface (View update history > Uninstall updates) or command-line servicing tools like wusa.exe and DISM, which properly reverse the package installation transaction.
