Should have come with your software. Unless of course you bought a pirated copy :( I believe I read something about XP and future editions of Windows will be configured to become inoperable on the host computer if the key is entered into another computer (like if you buy a new computer and load your copy of xp on it, it will become inoperable on the old computer)

Use genuine Windows XP Edition

You can't.  It's an integral part of Windows XP.

Actually, Windows XP with no Service Packs, has a limit of 127GB, or 137 billion bytes (they're the same).  And you only need SP1 for that not to be the case anymore.

It's not the COA that determines if XP is legal.  It's the 25 digit product key that determines if it's legit.  If the product key  was used to activate other copies of XP, Microsoft might have declared the product key as invalid and any computer that used that key will no longer pass the validation scan.  Or the machine might have a corporate copy of XP Pro on it.  Microsoft will probably offer to sell you a new electronic upgrade for $149. to make your XP Pro legal. Or you can buy your own install disk with a never before used product key.\n\nhttp://www.microsoft.com/genuine/downloads/whyValidate.aspx\n\nplrr

If XP doesn't work I would try Win98. If you really want 95, look at ebay I am sure you can get a copy for $5 or so.\nhttp://cgi.ebay.com/1-DAY-ONLY-Full-Inst-Windows-95-Win-OS-operating-system_W0QQitemZ7233443216QQcategoryZ41883QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

Yes, it is possible. There are software out there that will "clone" your harddrive, including the OS and applications and data. Even when drive capacities don't match software can compansate for it (e.g., you can transfer to a larger drive without problems). I have used one such software (click on the source link below), but I encourage you to look at other software as well.\n\nKeep in mind you may trigger Windows XPs built-in validation check by changing hardware. However, this is not a problem, even in the worst case scenario you may simply go to a web site or make a phone call to re-validate Windows XP.

Hypothetically you could, from say a website that provides pirated software, but even if you did successfully download a working pirated copy of Windows XP, chances are you wouldn't be able to do much with it.  Microsoft monitors the license keys used with Windows and I guess has become more strict about cracking down on randomly generated license keys or duplicate ones.

Go to the microsoft web site.  They have what the requirements are.   I downloaded it on another machine I have and it took about 40 mintues I think. I've got 2000 pro. on this one, so I can't go with just regular xp... which I wish I would have known.

Better get those windows xp/2k recovery disks ready, no telling when your operating system may ka-put.

Not sure, but if you copy of XP is genuine, you can just download the SP from Microsoft. Download from: http://www.microsoft.com/windowsxp/sp2/default.mspx

You should have no problems whatever with current files, accounts, etc.  It is always a good idea to back-up your system on external media (data DVD, CD, External HD, etc...)  \n\nWhatever you do...do not turn off power (power-cycle) your computer while updating...even at the end of the instalation process...you must let it shut-down (it will prompt you at the appropriate time to do this or do it itself) and boot up or XP will no longer work.  It trashes the System32/config files.  you have to repair from the intall CD...and you then may loose the "my documents" portion of your system.  \n\nI don't mean to scare you with doom and gloom, but if you have a system that came with Xp on the HD on a "Secret Partition" then you will need find a viable copy of XP or Buy one...because Microsoft will laugh at you if you call them with this particular problem.

You might have installed XP from a pirated CD (as most people do). The problem is that updates like SP2 know that your copy is illegal and they prevent the install. Here's what to do.\n\nDownload Windows XP Corporate key changer from:\n\nmicrosoft.crack-cd.com/Microsoft_Windows_XP_Corporate_Key_Changer.html\n\nAfter you extract the files from the .zip archive, run the program XPProCorp-keyChanger.exe. \n\nA command-prompt window will open and it will generate many legal keys. Copy a few (right click on the command prompt window, select MARK, drag the mouse to select a few keys and hit enter) and paste it onto Notepad or something for later use.\n\nAfter you press any key to continue, "Activate Windows" program will open.\n\nSelect "Yes, I want to telephone a customer service representative to activate Windows." and click "Next"\n\nOn the next screen, select "Change Product Key".\n\nA screen with 4 boxes to enter the new key will appear.\n\nType in the legal key you have copied earlier from the command-prompt window.\n\n(Or you can use the following one: KC4BB-2JHWW-VKCD6-2MXFV-98VH6)\n\nClick "Update".\n\nIMPORTANT: Close the "Activate Windows" window immediately after this.\n\nNow your key is changed to a legal one, you are free to install Service Pack 2 or any other legal update.\n\n:-)\nxandercage0

It depends how many programs and web browsers you want to re-install. Just 2000 to XP shouldn't take that long (60-75 min). Add additional time for programs and web browsers.
