• Remote Desktop - All versions of Windows XP--
including Home Edition--support Remote Assistance, which is
an assisted support technology that allows a help desk or
system administrator to remotely connect to a client
desktop for troubleshooting purposes. But Only Pro supports
the new Remote Desktop feature, which is a single-session
version of Terminal Services with two obvious uses: Mobile
professionals who need to remotely access their corporate
desktop, and remote administration of clients on a network.
You can access a Windows XP Remote Desktop from any OS that
supports a Terminal Services client (such as Windows 98
and, interestingly XP Home). XP Home can act as the client
in a Remote Desktop session; only Pro can be the server.
• Multi-processor support - Windows XP Pro supports
up to two microprocessors, while Home Edition supports only
• Automated System Recovery (ASR) - In a somewhat
controversial move, Microsoft has removed the Backup
utility from the default Windows XP Home Edition, though it
is available as an optional installation if you can find it
on the CD-ROM (hint: it's in the /valueadd folder). The
reason for this the integration of Microsoft's new
Automated System Recovery (ASR) tool into Backup. In Pro,
ASR will help recover a system from a catastrophic error,
such as one that renders the system unbootable. ASR-enabled
backups are triggerable from XP Setup, allowing you to
return your system to its previous state, even if the hard
drive dies and has to be replaced. Unlike consumer-oriented
features such as System Restore, ASR is not automatic: It
must manually be enabled from within the Backup utility in
Windows XP Pro. In any event, while there is a Backup
utility available for Home Edition, you cannot use ASR,
even though mentions of this feature still exist in the UI.
Confusing? Yes. But it's better than no Backup at all,
which was the original plan.
• Dynamic Disk Support - Windows XP Professional
(like its Windows 2000 equivalent) supports dynamic disks,
but Home Edition does not (instead, HE supports only the
standard Simple Disk type). Dynamic disks are not usable
with any OS other than Windows 2000 or Windows XP Pro, and
they cannot be used on portable computers. Likewise, Home
Edition does not include the Logical Disk Manager.
• Fax - Home Edition has no integrated fax
functionality out of the box, though it is an option you
can install from the XP Home CD.
• Internet Information Services/Personal Web Server -
Home Edition does not include the IIS Web server 5.1
software found in Pro.
• Encrypting File System - Windows XP Professional
supports the Encrypting File System (EFS), which allows you
encrypt individual files or folders for local security (EFS
is not enabled over a network). EFS-protected files and
folders allow users to protect sensitive documents from
• File-level access control - Any user with
Administrator privileges can limit access to certain
network resources, such as servers, directories, and files,
using access control lists. Only Windows XP Professional
supports file-level access control, mostly because this
feature is typically implemented through Group Policy
Objects, which are also not available in Home Edition.
• "C2" certification - Microsoft will attempt to have
Windows XP Professional certified with the "C2" security
designation, a largely irrelevant status, but one which
will not be afforded to Home Edition.
• Domain membership - Home Edition cannot be used to
logon to an Active Directory domain. For obvious reasons,
the Domain Wizard is also missing in Home Edition.
• Group Policy - Since Home Edition cannot be used to
logon to an Active Directory domain, Group Policy--whereby
applications, network resources, and operating systems are
administered for domain users--is not supported either.
• IntelliMirror - Microsoft lumps a wide range of
semi-related change and configuration management
technologies under the IntelliMirror umbrella, and none of
these features are supported in the consumer oriented Home
Edition. IntelliMirror capabilities include user data
management; centrally-managed software installation,
repair, updating, and removal; user settings management;
and Remote Installation Services (RIS), which allows
administrators to remotely install the OS on client
• Roaming profiles - This feature allows users to
logon to any computer in an Active Directory network and
automatically receive their customized settings. It is not
available in Home Edition, which cannot logon to an Active
• Multi-language support - Only Windows XP
Professional will ship in a Multi-Language version or
support multiple languages in a single install.
• Sysprep support - Windows XP Pro will support the
System Preparation (Sysprep) utility, while Home Edition
• RIS support - See the IntelliMirror heading in the
previous section; Home Edition does not support RIS
• Microsoft is shipping a 64-bit version of Windows
XP for Intel Itanium systems that mirrors the Professional
The following networking features are not included in Home
• The user interface for IPSecurity (IPSec)
• Simple TCP/IP services
• SAP Agent
• Client Service for NetWare
• Network Monitor
• Multiple Roaming feature
User interface features
Windows XP Home Edition has some different default settings
that affect the user interface. For example, Guest logon is
on by default in Home, but off in Pro. The Address bar in
Explorer windows is on in Pro by default, but off in Home.
During the beta period, Microsoft had intended to use a
business-oriented shell theme ("Professional") by default
in Pro and the "Luna" consumer theme in Home Edition. But
feedback from corporate users suggested that everyone liked
the consumer-oriented Luna theme better, and development of
the Professional theme was cancelled. Other user interface
features that are present in Pro but not Home include:
• Client-side caching
• Administrative Tools option on the Start menu (a
subset of the Admin tools are still present in Home,
