Objective 1.3: Compare and contrast basic features of Microsoft Windows editions

Cert: CompTIA A+ Core 2 (220-1202) V15 Domain: 1.0 Operating Systems Weight: Part of the 28% Operating Systems domain Depth: Compare and contrast. The candidate must distinguish editions, identify which features each supports, recognize upgrade paths between them, and apply hardware requirements.

What this objective tests

You should be able to pick the right Windows edition for a given use case, identify which features are edition-gated (BitLocker, RDP host, Group Policy Editor, domain join), and predict which upgrade paths are supported between editions and versions.

V15 covers both Windows 10 and Windows 11 because both are still in mainstream support during the exam's life. Windows 10 reaches EOL in October 2025, but it remains testable.

Key facts

Windows 10 Home:

• Consumer edition. Includes basic Windows features plus security defaults (Windows Defender, Windows Update).
• Lacks BitLocker, Group Policy Editor (gpedit.msc), Remote Desktop host (can connect out, can't be connected to), domain join.
• Limited to ~128 GB RAM.

Windows 10 Pro:

• Small business / power user edition. Adds BitLocker, gpedit.msc, RDP host, domain join, Hyper-V, Group Policy management.
• The right baseline for any office PC that joins a Windows domain or uses Microsoft 365 Business.
• Supports up to 2 TB RAM.

Windows 10 Pro for Workstations:

• Designed for high-end workstations: video editors, engineers, scientific computing.
• Adds support for server-grade hardware (Resilient File System / ReFS, persistent memory, NVDIMM-N, faster file sharing via SMB Direct).
• Supports up to 6 TB RAM and up to 4 CPU sockets.

Windows 10 Enterprise:

• Large organization edition, licensed via volume agreements (not retail).
• Adds DirectAccess, AppLocker, Credential Guard, Device Guard, Windows To Go (legacy), Branch Cache, advanced deployment tools.
• Same Pro feature set plus enterprise security and management.

Windows 11 Home:

• Same consumer position as Windows 10 Home. Requires Microsoft account during initial setup.
• Lacks BitLocker, gpedit.msc, RDP host, domain join (same edition limitations as Windows 10 Home).

Windows 11 Pro:

• Small business / power user edition. Same expanded feature set as Windows 10 Pro (BitLocker, gpedit.msc, RDP host, domain join, Hyper-V).

Windows 11 Enterprise:

• Volume-licensed organization edition. Same expanded enterprise features as Windows 10 Enterprise plus Windows 11-era additions.

N versions:

• European Union editions that ship without Windows Media Player and certain media playback codecs (regulatory requirement from EU antitrust action).
• Functionally identical otherwise. Users can install the Media Feature Pack to restore the missing components.
• Tested as a "did you know N exists" recognition item, not commonly deployed outside the EU.

Domain vs workgroup:

• Workgroup: peer-to-peer network, each PC manages its own users and shares. Suited to ~10 PCs or fewer.
• Domain: centralized Active Directory authentication and policy. Required for enterprise management at scale. Only Pro and above can join.
• Choosing the right model is part of edition selection. Home edition can't join a domain, so it's wrong for a Windows-domain office.

Desktop styles / user interface:

• Windows 10 and 11 have notably different default looks: centered taskbar and Start menu on 11, left-aligned on 10.
• Windows 11 added rounded corners, Snap Layouts, Widgets, redesigned Start menu.
• Edition doesn't change UI; version does.

Availability of Remote Desktop Protocol (RDP):

• RDP host (incoming) is only available on Pro and above.
• RDP client (outgoing) is available on all editions including Home.
• "I want to remote into this PC from elsewhere" requires Pro or higher.

RAM support limitations:

• Home: ~128 GB
• Pro: 2 TB
• Pro for Workstations: 6 TB
• Enterprise: 6 TB
• Always 64-bit Windows; 32-bit Windows hasn't been a thing for new editions for years.

BitLocker:

• Full-disk encryption built into Windows. Pro and above only on standard Windows 10/11 editions.
• Uses TPM 2.0 by default to seal the encryption key to the hardware.
• Essential for laptops carrying sensitive data, required for many compliance frameworks.

gpedit.msc (Group Policy Editor):

• Local Group Policy Editor for tweaking Windows settings beyond what the Settings app exposes.
• Pro and above only. Home users have to use Registry Editor for most equivalent changes.

In-place upgrade:

• Upgrade Windows version (10 to 11) or edition (Home to Pro) without wiping user data, settings, or apps.
• Edition upgrade: Settings > System > Activation > Change product key. Enter a Pro key, Windows upgrades the edition in place.
• Version upgrade (10 to 11): in-place upgrade via Windows Update or Installation Assistant.

Clean install:

• Fresh install on the target edition, with backup-and-restore of user data.
• Used when the upgrade path is unsupported or the existing install is too damaged.

Trusted Platform Module (TPM):

• Hardware security chip required for Windows 11 (minimum TPM 2.0).
• Stores BitLocker keys, biometric templates, certificates.
• Discrete TPM chip or firmware TPM (fTPM) built into modern CPUs both qualify.

Unified Extensible Firmware Interface (UEFI):

• Modern firmware standard replacing legacy BIOS.
• Required for Secure Boot, GPT-partitioned drives, and Windows 11.
• Most PCs from ~2012 onward ship with UEFI.

Common gotchas

• Quoting Home for a domain-joined office. Home can't join a domain. Pro is the minimum for a Windows domain environment.
• BitLocker missing on Home. User wants full-disk encryption on their Home laptop. Need to upgrade to Pro or use a third-party encryption tool.
• RDP into a Home edition PC. Doesn't work. Either upgrade to Pro or use third-party remote tools (Splashtop, AnyDesk, ScreenConnect).
• TPM not enabled in firmware. PC has TPM 2.0 hardware but the firmware setting is off. Windows 11 install refuses until TPM is enabled in BIOS/UEFI.
• Legacy BIOS still configured. PC supports UEFI but is configured for legacy BIOS boot mode. Switching to UEFI may require converting the drive from MBR to GPT (mbr2gpt.exe).
• Upgrade path skipped. Trying to upgrade Windows 7 Home directly to Windows 11. Usually requires Windows 10 as an intermediate step or a clean install.

Real-world context

For office PC procurement:

• Single home user, no work-from-home requirements: Home is fine.
• Office worker on a Microsoft 365 Business plan: Pro is the right baseline. Domain join, BitLocker, RDP host all matter for IT manageability.
• Engineer running CAD or rendering, needs >128 GB RAM: Pro for Workstations.
• Enterprise with Active Directory, compliance requirements, Intune management: Enterprise via volume licensing.

Most SMB and prosumer hardware ships with Windows 11 Pro now. If a vendor sent the office PCs with Home, plan to upgrade them to Pro before joining the domain.
