Automate the installation of Windows XP

You can create a CD that can install Windows automatically, putting in all the details and answering all the dialog boxes. The secret behind the unattended nature of the whole thing is the answer file, which tells Windows what to do while it’s installing. The answer file can be created using Windows Setup Manager. Using this tool, you can make the answer file so powerful that you can even tell
Windows to include or exclude individual components, set the display resolution, and
more. Here’s how you do it.

Bypass Windows File Protection in Windows XP


There are two different solutions, depending on whether you have SP2 installed or not.

If you don’t have SP2 installed
Locate the file sfc_os.dll, which should be in your System32 folder. Copy it and name it sfc_os.bak. Open this file using a hex editor such as XVI32,which is an excellent freeware. This is an extremely simple edit and does not require an editor with advanced features. All you need to do is change two values. The location of these values will vary depending on whether you’re using Windows XP without a Service Pack or Windows XP with SP1, but the actual hex values to change will be the same.For Windows XP with no Service Pack installed, go to offset 0000E2B8 (E2B8 hex). For Windows XP with SP1, go to offset 0000E3BB (E3BB hex). At those offsets, change the hex values 8BC6 to 9090.Note: Depending on your hex editor, you may see the value separated by a space, as in “8B C6”. If you can’t find the values, do not proceed. It could be that your version of XP is different. The edit as described here only applies to English retail versions of Windows XP.

Create A Special Folder In Windows Explorer


1.In the Registry Editor, navigate to HKEY_CLASSES_ROOT\CLSID. Create a new1 key with a Globally Unique Identifier(GUID). The GUID is a 128-bit identifier that is usually generated by Windows. This can be a random number that is used touniquely identify COM objects. Create a key using this random GUID:{FD4DF9E0-E3DE-11CE-BFCF-ABCD1DE12345}

Creating A Windows XP Boot CD With SP2

1. First, create a folder on your hard drive e.g. D:\XPCD. Now, copy the entire contents of existing Windows XP CD to this folder. The Windows XP SP2 executable file is an archive of the Service Pack 2 files, so you can use WinZip and extract SP2 files to another folder say D:\SP2. Now, locate update.exe under D:\SP2. This can be found inside the sub-folder named ‘update’. Go to the DOS command prompt and change your directory to this ‘update’ folder. Run the commandcommand “update where/integrate:"(dir)" “(dir)” is the directory you saved the Windows XP CD files to, ( “D:\XPCD” in ourcase). This will start integrating SP2 into the Windows XP Installation files saved at D:\XPCD. You should get message box confirmation that integration was successful.Now the D:\XPCD folder contains Windows XP installation files with SP2 integrated.

Scheduling Connecting And Disconnecting From Your ISP

With many ISPs using PPPoE-based connections, and many ISPs having awkward schemes such as night-unlimited it’s a good idea to schedule your dialling process rather than staying up late at night.Once connected, your downloads can start. You can also schedule to connect to VPNs.

First we create a batch file. Start Notepad (or any other text editor). Enter the following:
RASDIAL

WINDOWS XP Hidden Applications

 

Go to Start > Run and type the executable name (eg: charmap) to run these applications.

Change Your IP in windows xp

1.Goto start>>run>>type 'command' and hit enter

Now you will get an MSDOS prompt screen.

2. Type "ipconfig /release" and hit enter




Create A Bootable XP CD That Pre-installs Additional Programs

To create a bootable XP CD that pre-installs additional programs, first install Windows Unattended CD Creator (WUCC). You need to have Microsoft .NET Framework 1.1 or higher installed.Windows Unattended CD Creator is a very small application that will help you create an user-customized Windows bootable CD. You can choose which drivers, components or hot fixes to be installed and you can even set your network settings. All you need to do in a normal Windows installation is taken cared of by this little application, so you can install your operating system in the fastest way possible

Space Tugboat Could Help Move Inexpensive Payloads in Orbit

 
A Seattle company has announced plans to build a new spacecraft that, like its Earth-bound counterparts, is all about moving other vehicles around. Spaceflight Inc. is designing what it’s calling the Sherpa to fulfill the need for an orbital tugboat that can move payloads, such as satellites, to different orbits around Earth.

The U.S. military is already investing tens of billions of dollars to make its jet fighters less visible to radars and infrared sensors. Now the Pentagon wants the defense industry to come up with a system that can cloak fighters from another telltale type of radiation: ultra-violet energy from the sun.
