what is the different between windows xp home edition and
professional ?

Answer Posted / m.e.chandrasekar

Windows XP Home Edition Overview
Windows XP Home Edition includes a number of enhancements
over Windows 2000 Professional. These include:

* Improved software (application) and hardware compatibility
* Simplified security
* Simplified log-on featuring new "welcome" screen
* Fast user switching
* A new user interface featuring context-sensitive, task-
oriented Web views
* Enhanced support for digital media (movies, pictures,
music)
* DirectX 8.1 multimedia libraries for gaming




Windows XP PRO Edition Overview
* Power user 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 one.
* 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.

* Security 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 allows users to protect sensitive documents from
other users.
* 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.

* Management 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 systems.
* 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
Directory domain.

* Corporate deployment 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 will not.
* RIS support - See the IntelliMirror heading in the
previous section; Home Edition does not support RIS
deployments.

* 64-bit Edition Microsoft is shipping a 64-bit version of
Windows XP for Intel Itanium systems that mirrors the
Professional Edition feature-set.

Networking features
* The following networking features are not included in Home
Edition: The user interface for IPSecurity (IPSec)
* SNMP
* 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, however).
Windows Xp home does not support security politics, remote
desktop, domains, does not support properly wireless network
change (you have to basically restart computer if you want
to apply new settings), does not save password for network
drives and so.
