OS Types, Installation and Windows Tools
Core 2 OS questions test Windows editions, installation methods, upgrade concerns, boot methods, filesystems, utilities, and command-line tools.
How to study for CompTIA A+
Treat each A+ item as a support decision: identify the device, symptom, layer, safest next step, user impact, and documentation requirement.
Core concepts
Concept 1
Operating system support depends on edition, lifecycle, hardware requirements, filesystem, drivers, and application compatibility.
Exam cue: Confirm OS edition and hardware requirements.
Concept 2
Installation and upgrade choices must protect user data, licensing, drivers, recovery options, and business continuity.
Exam cue: Back up and verify compatibility before upgrades.
Concept 3
Windows administrative tools and command-line utilities help diagnose services, disks, users, network configuration, and performance.
Exam cue: Choose the tool that observes the failing layer.
Risk pitfalls and guardrails
Upgrading without checking application or driver compatibility.
Guardrail: Avoid answers that skip verification, expose user data, ignore recent changes, replace parts too early, or bypass policy for convenience.
Using a network tool to troubleshoot a disk issue.
Guardrail: Avoid answers that skip verification, expose user data, ignore recent changes, replace parts too early, or bypass policy for convenience.
Confusing clean install, upgrade, repair, image, and recovery options.
Guardrail: Avoid answers that skip verification, expose user data, ignore recent changes, replace parts too early, or bypass policy for convenience.
Memory anchors
Clean Install
A clean install installs an OS fresh and can remove existing applications and data.
In-Place Upgrade
An in-place upgrade preserves supported applications, settings, and data when compatible.
GPT
GUID Partition Table supports modern partitioning and UEFI boot scenarios.
MBR
Master boot record is an older partitioning style with legacy boot use cases.
Device Manager
Device Manager shows hardware and driver status in Windows.
Event Viewer
Event Viewer displays Windows logs useful for troubleshooting services, crashes, and security events.
Disk Management
Disk Management creates, formats, extends, and assigns drive letters to volumes.
Task Manager
Task Manager shows processes, performance, startup apps, users, and services.
ipconfig
ipconfig displays or manages Windows IP configuration.
sfc
System File Checker scans and repairs protected Windows system files.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
