    On May 4th, 2004, at the WinHEC 2004 engineering conference, Microsoft unveiled Windows Code-Named "Longhorn", Build 4074. This build has a number of improvements over the previous version, Build 4051, which was released in October 2003 at the Microsoft Professional Developers Conference (PDC 2003). People who attended the PDC will be pleased to know that the product keys recieved at that conference will successfully activate this build. The downside to Longhorn is the massive memory consumption issues. WinFS, the new database storage technology, uses upwards to 200MB of RAM, and can easily slow down a system. With this guide, we will show you how to optimize Longhorn to achieve a large performance increase.


    --------------------------------------------------------------------------------

    Uninstall Un-needed Windows Components

    Longhorn by default ships with a lot of new technologies turned on by default. The problem with this is that some people don't have the appropriate hardware to take advantage of these technologies, and as a result, they are consuming resources that could be used elsewhere. Also, some components, such as WinFS, use a lot of memory for no apparent reason. In this section we will show you how to remove such un-necessary items.

    First, we will need to modify SYSOC.INF. This file tells the Add/Remove Programs applet what components can be removed by end users. By removing the "HIDE" text from this file, all options become available for us to modify as we see fit.

    To do this, click Start, Run. Type "notepad C:\WINDOWS\INF\SYSOC.INF". Press OK.
    In the Notepad window, click Edit, Replace. In the "Find what" box, type HIDE. Leave the "Replace with" box empty. Next, click Replace All.
    Save the file and close Notepad.
    Click Start, Control Panel. Click "Add/Remove Programs".
    In the Add/Remove Programs dialog, on the left side, click "Add/Remove Windows Components".
    In the Windows Component Selection window, uncheck the following items:

    %TabletPCRuntime_desc%
    Biometric Base Components
    Biometric Logon Support
    MSN Explorer
    Windows File System Services
    Windows Messenger

    --------------------------------------------------------------------------------
    Disable Un-needed Services

    Longhorn has some new system services, some of which can cause slowdowns and lockups. To speed up Longhorn, we will want to disable a number of services. To do this, follow these instructions:

    Click Start, Run. Type "services.msc" and press OK.
    To disable a service, double click on it. Under the "Startup Type" field, select "Disabled".
    Disable the following services:

    Automatic Updates
    Base Firewall Engine
    Castle Discovery
    Digital ID Management Service
    Error Reporting Service
    Font Cache Service
    Internet Connection Firewall (ICF) / Internet Connection Sharing (ICS)
    IPSEC Services
    Logon Hours
    Net Logon
    NetMeeting Remote Desktop Sharing
    Offline Files Service
    Remote Registry Service
    Smart Card
    Smartcard Removal Policy
    System Maintenance Service
    System Restore Service
    Windows Event Forwarding
    It is recommended that you restart your computer after this step.


    --------------------------------------------------------------------------------

    Windows Explorer: Performance Options

    Click Start, right click on "Computer", and click Properties.
    Click on the Advanced tab. Under Performance, click Settings.
    Uncheck these options:

    Animate windows when minimizing and maximizing
    Fade or slide menus into view
    Fade or slide tooltips into view
    Fade out menu items after clicking
    Show preview and filters in folder (disabling this is CRUCIAL!)
    Show shadows under menus
    Slide open combo boxes
    Slide taskbar buttons
    Use a background image for each folder type
    Close the Performance Options & System Properties dialogs.

    Click Start, Run. Type "control folders". Press OK.
    Click the View tab. Modify the settings as shown below.

    Uncheck:

    Automatically search for network folders and printers
    Choose smart icon size when opening new windows
    Display simple folder view in Explorer's Folders list
    Use Domain Folder Sharing Wizard
    Use Simple File Sharing
    Check:

    Launch folder windows in a separate process
    Show text filenames instead of ink titles

    --------------------------------------------------------------------------------

    Windows Explorer: Fixes

    New Folders
    The Windows shell, also known as Explorer, is somewhat buggy in this build. For instance, the "New Folder" command in just about every area of the operating system doesn't work. It is a very weird bug, but we do have a fix thanks to BetaOne. Thanks to DJJoshee for submiting the fix!

    Create a reg file using Notepad with the following in it:

    Windows Registry Editor Version 5.00

    [HKEY_CLASSES_ROOT\.Folder]
    @="folderfile"

    [HKEY_CLASSES_ROOT\Folderfile]
    @="Folder"

    [HKEY_CLASSES_ROOT\Folderfile\DefaultIcon]
    @="%SystemRoot%\\system32\\SHELL32.dll,4"

    [HKEY_CLASSES_ROOT\Folderfile\shell]
    @="New"

    [HKEY_CLASSES_ROOT\Folderfile\shell\New]
    @="New Folder"


    Remove the Search & Help and Support Icons from the Desktop
    For some unknown reason, after using Longhorn for a certain amount of time, two new icons will appear on your desktop. They are Search, and Help and Support. Normally, you cannot delete these. But we have found a way to remove them, by modifying the registry.

    WARNING: Modifying the registry incorrectly can cause problems and system instabilities. Please be careful.

    Click Start, Run, and type "regedit". Press OK.
    Delete the following keys from the registry:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Desktop\NameSpace\{018e3123-c842-41d4-94a0-a0c54962a96c}
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Desktop\NameSpace\{7D455D5A-1DE4-4c25-8E75-1F7288D2EB89}
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Desktop\NameSpace\DelegateFolders

    --------------------------------------------------------------------------------

    Frequently Asked Questions

    Q: Where can I download Windows “Longhorn�?
    A: You can obtain Longhorn from the Microsoft Developer Network (MSDN) if you are an MSDN Universal subscriber. We will NOT be going into any detail of where you can obtain Longhorn elsewhere.

    Q: What is the full build number of Longhorn?
    A: Windows® Code Name “Longhorn�
    Evaluation Copy. Build 4074.idx02.040425-1535

    Q: How do I change the “Registered User� information?
    A: Click Start, Run. Type “regedit�.
    Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion, and edit the "RegisteredOwner" and "RegisteredOrganization" keys to your liking.

    Q: What Internet Browser do you suggest I use in Longhorn?
    A: This is really up to your own preference. You could use Internet Explorer, Avant Browser, MyIE2, Opera, Mozilla, Mozilla Firefox, or other browsers.

    Q: Why does Longhorn slow down after being logged on after a certain amount of time?
    A: This issue is most likely caused from memory being swapped around. The simplest way to solve this is to log off or reboot.

    Q: What Anti Virus applications work with Longhorn?
    A: Norton AntiVirus 2003 and higher most likely work (these have not been tested yet under this build). We recommend you use Grisoft AVG Anti-Virus Free Edition 6.0, which has real-time protection, and is light weight (does not use a lot of system resources). AVG 6.0 Free Edition is available from http://www.grisoft.com/

    Q: What versions of Microsoft Office work under Longhorn?
    A: Microsoft Office XP and 2003 work under Longhorn and have been tested. Office 2000 is compatible as well but has several issues.

    Q: What editions of Longhorn will be available when it is completed?
    A: We don’t know the answer to this as Microsoft's roadmap changes around, but currently, there are planned versions of Home Edition, Professional, and Media Center Edition.

    Q: Where can I find a timeline of the Longhorn builds & leak dates?
    A: You can find these around the internet, simply by searching Google. But, for our readers’ convenience, we have compiled an easy to follow timeline with most of the information you need at the end of this guide.


    --------------------------------------------------------------------------------

    Changes since build 4051 & 4053:

    New visual style titled "Jade", features a light blue color.
    There are many more sidebar tiles included in this release. For the list, see the section below titled "Sidebar Tiles List".
    The Windows Shell ("Windows Explorer") has been optimized and as a result, browsing your system is faster.
    Device Manager has been removed, Hardware and Devices has taken its place, and has a shortcut on the Start Menu.
    The Taskbar Properties dialog has been somewhat redone, with more options available to control the sidebar.
    There is a new shutdown button in the start menu. Windows will select the shutdown method that is best for your system (Stand by, Hibernate, etc). You can access the other options via a dropdown list which is found next to the shutdown button.
    The networking core in this build seems to be fixed.
    Drivers now seem to be required to have a signature for Longhorn; this build allows you to get around it though.
    The clock tile has been locked to the bottom of the sidebar; the tile now includes more faces, and an alarm feature.
    Notification History tile allows you to view previous notification items (EG: "14 days left for activation", etc).
    Checkboxes and radio buttons in Mozilla Firefox, Kazaa Lite, etc are now fixed.

    --------------------------------------------------------------------------------

    Known issues in this recent build 4074

    Creating new folders using Windows Explorer does not work. To create new folders, you need to use the mkdir command. See the section above entitled "Windows Explorer: Fixes" for a work-around.
    Windows Explorer still consumes large amounts of memory with the sidebar on, although the memory leakage is not nearly as severe as it was in previous builds (4015, 4029, 4051, 4053).
    Synchronize tile does not work when WinFS is disabled.
    The basket tile doesn't really seem to serve a purpose in this build.

    --------------------------------------------------------------------------------
    Sidebar Tiles List

    Basket: This tile is used to store files that you want to send or copy. It is very similar to "My Briefcase" feature.
    Contacts: This tile displays your Windows Messenger contact list on the sidebar. WinFS and Windows Messenger 6 are required for proper function.
    News Feed: Displays news items from the Longhorn Developer Center on MSDN. You can change the feed this tile uses for use with other sites.
    Notification History: This tile displays all previous notifications.
    People Nearby: I am really not sure what this tile does but we are assuming it does what the name suggests; it displays contacts that are nearby and available.
    Clock: This tile by default has an analog face with the time and date below it. You can change the face to your liking by opening the Properties dialog for this tile. Also includes an alarm clock, and international time.
    Quick Launch: This tile displays the items in your Quick Launch folder (which is located in %userprofile%\Application Data\Microsoft\Internet Explorer\Quick Launch).
    Classic Tray: This tile displays the items that were once next to the clock on the taskbar. To access all the icons, click on the tile, and a flyout will appear.
    Slide Show: This tile displays a slide show of all the pictures contained in your “My Pictures� folder. This is great to enable if you have family photos that you enjoy to see.
    Sync: This tile is used for file synchronization. To work properly, this tile requires WinFS to be enabled.
    Power (Transient): This tile displays the status of a battery in a laptop computer. You need to set the Transient value to 0 in the registry in order for this tile to work.
    Web Host Tile (Transient): This tile is a traffic webcam tile similar to what was seen in earlier builds. You need to set the Transient value to 0 in the registry in order for this tile to work.

    Longhorn Timeline

    Build 3683 – Leaked November 19, 2002. First public leak of Windows “Longhorn�. This build is from Lab 06; contained extras from the Avalon lab that are not seen in other builds (new display properties dialog box, etc). Some features were broken, such as Internet Explorer downloads.
    Build 4008 – Leaked February 28, 2003. Second leak. Contained a cleaner version of the “Plex� visual style; Internet Explorer downloads fixed, more sidebar tiles.
    Build 4015 – Leaked April 2003. Third Leak. We prefer to call this the build from hell. Not much different from 4008, except the new style taskbar was enabled by default and could only be disabled by turning off the sidebar. This build consumed HUGE amounts of memory in very little time.
    Build 4029 – Leaked September 23, 2003. Fourth leak. Displayed the beginnings of the new style Explorer windows, contained a new sidebar clock.
    Build 4051 – Leaked October 25, 2003. Released at the Professional Developer Conference, this build was supposed to be quite stable, as it was the first developer preview of Longhorn, but it ended up being horrible as far as being able to develop and test sidebar tiles went. It just leaked too much memory which hindered the ability to do anything useful with it. Introduction of the “Slate� theme, “Plex� was removed.
    Build 4053 – Leaked March 1, 2004. Explorer memory leak seems to have been fixed for the most part. More responsive than 4051.
    Build 4074 – Released at the WinHEC Engineering Conference on May 4, 2004. New features include the Jade theme, more sidebar tiles, etc.
