MMC Snap-ins for Windows Support for A+
Short answer
MMC snap-ins are specialized management consoles for Windows subsystems. For A+ tasks the technician should know which snap-in to open for a given symptom: Event Viewer for logs, Device Manager for driver/hardware errors, Disk Management for partitions, Performance Monitor for extended counters, etc. Often the workflow is: observe symptom -> open Task Manager -> if hardware/driver suspected open Device Manager -> if logs required open Event Viewer -> if disk layout or partition issues open Disk Management.
Why it appears on the exam
- Which MMC would you use to check for a driver error? (Device Manager) - Which tool shows scheduled automated jobs? (Task Scheduler) - Which tool would you check to confirm a certificate trust path? (Certificate Manager)
Key concepts
Concept 1
Required terms
Event Viewer: Centralized log viewer for system, application, and security events; useful for diagnosing crashes and driver errors. Disk Management: View and modify disk partitions, volumes, drive letters, and basic disk initialization tasks. Device Manager: Lists hardware devices and drivers, allows driver updates, rollbacks, and viewing device status codes. Task Scheduler: Schedules automated tasks; used to check for unexpected scheduled jobs that run scripts or programs.
Example
Blue screen or repeated application crash: check Event Viewer for critical errors and source event IDs.

How MMC Snap-ins for Windows Support works
MMC snap-ins are specialized management consoles for Windows subsystems. For A+ tasks the technician should know which snap-in to open for a given symptom: Event Viewer for logs, Device Manager for driver/hardware errors, Disk Management for partitions, Performance Monitor for extended counters, etc. Often the workflow is: observe symptom -> open Task Manager -> if hardware/driver suspected open Device Manager -> if logs required open Event Viewer -> if disk layout or partition issues open Disk Management.
Example
New external drive not visible: open Disk Management to assign a drive letter or initialize the disk.
Concept 3
Common confusion
Learners may try to use Disk Management to recover files or think Performance Monitor replaces Task Manager. Also, Local Users and Groups is not available or used the same way on domain-joined machines.
Example
Device stopped functioning after driver update: open Device Manager and roll back the driver or view device status.
Concept 4
Core 2 (220-1202) question cues
Which MMC would you use to check for a driver error? (Device Manager); Which tool shows scheduled automated jobs? (Task Scheduler); Which tool would you check to confirm a certificate trust path? (Certificate Manager).
Example
Blue screen or repeated application crash: check Event Viewer for critical errors and source event IDs.
