How to install Windows from the I386 folder

pratik — Fri, 28 Aug 2009 10:16:45 +0000

Most people cannot figure out how to install Windows XP, 2000, or 2003 from the I386 folder. It is really quite simple. They are looking for a file named Setup.exe or Install.exe. Well, it’s neither of them. If you have Vista or 2008 or newer like Windows 7 there is no I386 folder that you can install from.

I guess Microsoft did not want just anyone to install Windows without inserting the CD and using the Autorun. But Autorun does not work if you are installing from a DOS window, so now what.

OK, here it is plain and simple, if you open the I386 folder and scroll down to the W’s you will find Winnt.exe and Winnt32.exe. The Winnt32.exe is the setup program used when you are in Windows. The Winnt.exe file is for DOS.

However, I have found that sometimes I run across a Windows 2000 installation CD that errors out when I try to use the Winnt32.exe. So I simple start the install while in Windows using the Winnt.exe file. It’s a little slower but it works fine.

If you want to install the Recovery Console, you need to use the switch /cmdcon when starting Winnt32.exe. This switch only works on the Winnt32.exe file.

Below is a list of switches that you can use, Winnt32.exe can handle up to 8 switches.

WINNT.EXE
/a	Enables accessibility options. This option is not recommended for most users
/e: command	Specifies a command that is to be executed at the end of GUI-mode Setup. Commonly used to launch automated application setup routines to complete the installation
/i: inffile	Specifies the file name of the setup information file. By default, this is Dosnet.inf. This option is not recommended
/r: folder	Specifies that a folder is created during setup. The folder remains after Setup finishes.
/rx: folder	Copies a folder you create into the system folder. This option is generally used to copy drivers that are not part of the standard Windows 2000 distribution, and can be used multiple times to copy multiple folders The folder is deleted after Setup finishes
/s: sourcepath	Specifies the location of the Windows source files. The location must be a full path of the form w:\[path] or \\server\share[\path] This option is required only if the files are not located in the current folder.
/t: tempdrive	Specifies which partition setup will use to store temporary files. This option is not recommended. If you do not specify a location, Setup attempts to locate a drive for you.
/u: answer file	Performs an unattended Setup using an answer file. Answer files are used to bypass the interactive questions asked of the user during setup and can even be used to automate the setup process completely. You must also use /s . with this switch
/udf: id [, UDB_file]	Indicates an identifier ( id ) that Setup uses to specify how a Uniqueness Database (UDB) file modifies an answer file (see /u ). The /udf parameter overrides values in the answer file, and the identifier determines which values in the UDB file are used. If no UDB_file is specified, Setup prompts you to insert a disk that contains the $Unique$.udb file.
WINNT32.EXE
/checkupgradeonly	Checks the target machine for upgrade compatibility with Windows. For Windows 9x or ME Setup creates a report named Upgrade.txt in the Windows installation folder. For Windows NT 3.51 or 4.0 upgrades, it saves the report to the Winnt32.log in the installation folder.
/cmd:command_line	Allows you to specify a command before the final phase of Setup. This would occur after your computer has restarted twice and after Setup has collected the necessary configuration information, but before Setup is complete.
/cmdcons	Installs the Recovery Console It is only used post-Setup.
/copydir:folder_name	Creates an additional folder within the folder in which the Windows files are installed. You can use /copydir to create as many additional folders as you want.
/copysource:folder_name	Creates a temporary additional folder within the folder in which the Windows files are installed. Unlike the folders /copydir creates, /copysource folders are deleted after Setup completes.
/debug [ level ] : [filename ]	Creates a debug log at the level specified. The default log file is C:\ %Windir%\Winnt32.log, with the debug level set to 2. The log levels are as follows: 0-severe errors, 1-errors, 2-warnings, 3-information, and 4-detailed information for debugging. Each level includes the levels below it.
/m: folder_name	Specifies that Setup copies replacement files from an alternate location. Instructs Setup to look in the alternate location first and if files are present, use them instead of the files from the default location.
/makelocalsource	Copies all installation source files to your local hard disk. Use /makelocalsourcewhen installing from a CD to provide installation files when the CD is not available later in the installation.
/noreboot	Instructs Setup to not restart the computer after the file copy phase of winnt32 is completed so that you can execute another command.
/s: sourcepath	Specifies the source location of the Windows files. To simultaneously copy files from multiple servers, specify multiple /s sources. If you use multiple /s switches, the first specified server must be available or Setup will fail.
/tempdrive:drive_letter	Directs Setup to place temporary files on the specified partition and to install Windows on that partition.
/unattend	Upgrades your previous version of Windows. All user settings are taken from the previous installation, so no user intervention is required during Setup.
/unattend [ num ] :[ answer_file ]	Performs a fresh installation in unattended Setup mode. The answer file provides Setup with your custom specifications. Num is the number of seconds between the time that Setup finishes copying the files and when it restarts your computer.Answer_file is the name of the answer file.
/udf: id [ ,UDB_file]	Indicates an identifier ( id ) that Setup uses to specify how a Uniqueness Database (UDB) file modifies an answer file (see /u ). The /udf parameter overrides values in the answer file, and the identifier determines which values in the UDB file are used. If no UDB_file is specified, Setup prompts you to insert a disk that contains the $Unique$.udb file.

Disable Windows Search Indexing

pratik — Wed, 19 Aug 2009 12:50:38 +0000

If you don’t use Windows XP’s built-in search often; (like every day), disabling indexing can significantly speed up your PC.

By default Windows XP indexes files on your hard drive and stores them in memory to speed up its’ built-in search. But if you rarely use Windows search, turn off indexing to free up memory and CPU horsepower for the files and applications you actually do use. A few simple how-to steps after the jump.

To turn off indexing:

Open up “My Computer.”
Right-click on your hard drive (usually “C:”) and choose “Properties.”
Uncheck the box at the bottom that reads “Allow Indexing Service to…”
Click OK, and files will be removed from memory. This removal may take a few minutes to complete.

To disable the indexing service:

In the “Start” menu, choose “Run.”
Type “services.msc” and press Enter.
Scroll-down to “Indexing Service” and double-click it.
If the service status is “Running”, then stop it by pressing the “Stop” button.
To make sure this service doesn’t run again, under “Startup Type:”, choose “Disabled.”

Windows search will still work if you perform these steps, but it will work more slowly than if indexing was enabled.

Patching Windows xp without running WGA validation

pratik — Wed, 27 May 2009 12:12:09 +0000

How to patch without running WGA validation

The following steps will allow you to install all Windows security patches on a new build of XP, without installing or running WGA on the machine:

Step 1: Install and activate XP. For XP SP2 only (not XP SP3), you must also download and install the patch described in KB article 898461, which updates the installer program and ensures that your system will receive future updates.
Step 2: In either version of XP, click Start, Control Panel, Security Center, Automatic Updates. Choose Download updates for me, but let me choose when to install them.
Step 3: Whenever you see a yellow-shield icon in the notification area (previously known as the system tray), click the icon and then choose Custom install.
Step 4: Scroll to the bottom of the patch window and uncheck Windows Genuine Advantage Notification (KB905474), as shown in Figure 1. (For more info, see Microsoft KB article 905474 to read the company’s description of WGA Notification.)Figure 1. Uncheck KB905474 to prevent WGA from being installed on the system.
Step 5: After you click Install, check Don’t notify me about these updates again in the resulting dialog to prevent WGA from being included in future Windows updates (see Figure 2). Click OK.

Figure 2. Check this option to avoid being offered WGA Notifications as part of future updates.

From this point forward, every time you update your system, review the patches being offered to you and deselect those you don’t want before proceeding with the installation.

Microsoft occasionally updates the WGA Notifications tool, so you can count on its being offered to you again, despite your choice in Step 5 above. The explanation Microsoft officials gave me for this decision is that the company feels it’s wise to reinstall WGA periodically to ensure that customers haven’t been the victim of unscrupulous consultants who use illegal media when reinstalling your operating system.

There’s a flaw in this thinking: the reason many of these consultants use the wrong media is that Microsoft doesn’t make it easy to get replacements for your Windows installation discs. It’s also difficult to get up-to-date installation media unless you’re one of Microsoft’s enterprise-level customers.

Microsoft’s recommendation that you set your machine to update automatically as the best way to protect it is also flawed. These days, our PCs aren’t just simple e-mail and Web terminals. They’re crucial to all our work, and if they’re disabled we can’t make a living. For example, if a Windows update causes our Internet connection to break because of a conflict with a third-party security program — as has happened many times in the recent past — we might be unproductive for hours or days.

Also, if you enable Automatic Updates, you may be as dismayed as I was to learn that Microsoft treats legitimate customers like thieves. The WGA Notifications patch described in KB article 905474 automatically installs if Automatic Updates is empowered to act without permission. In that case, you either have to run the WGA tool the next time you reboot or press Cancel every time you start your system.

If you install WGA Notifications on XP, this dialog box will reappear each time you reboot until you click Next and run the process.
