I bought a computer not to long ago at a yard sell.it works fine.other that it tells me that the microsoft program cant pass validation because it is not a valid copy.i want to know if i can change my os without having to buy a program and that wont cost me any money.
You can search online for a Windows installation cd or restore cd based on your system. I got a used dell optiplex desktop pentium III but then I had a hard disk failure and had to buy a new one. But then I had no OS other than Windows 2000. I was able to get a Dell Windows XP Professional installation CD for around $10 on Amazon.com. Easier than purchasing a license while avoiding the potential problems with pirating.

Re: changing an os
As it is illegal to use pirate software, it is possible to make it a legal copy, it will cost around £90-£100, for a liceice code, or you can download anti-genuine authentication tools of the net to make your copy look guenuine!

if that the case, its either yo don't have the original serial key for your windows xp. if ever that is, go and reinstall your xp and try to download a program for the validation of your xp. it will bypass the authentication security and your xp will be authenticated.
If you purchased the computer with Windows XP Professional pre-installed from a computer-store, then the computer-store is guilty of "software piracy". Call Microsoft (1-800-R-U-LEGIT) and report the store for not selling you a "genuine" copy of Microsoft software.
If you have a brand-name computer (e.g., Dell, eMachines) purchased since 2001, it came with a genuine copy of Windows, and a decal (either on the side of a desktop computer, or on the bottom of a laptop) with a valid 25-character product-key.
Contact that manufacturer, and order a replacement set of the "System Restore" CD/DVD disks. Reinstall Windows using those disks and the product-key.
If you have a "bootleg" version of Windows, you need to follow the on-screen instructions to "get genuine", i.e., use your credit-card to purchase a valid product-key from MIcrosoft.
Or, purchase a Windows 7 Upgrade package from a computer-store, and install Windows 7.

If you have the original CD you should be able to reinsert it into CD player and pass validation. If you don't have the CD, then you license key for your copy of Windows was tagged as invalid for some reason in their databases. You will have to contact microsoft.com to get it corrected.
The problem is with the actual key that you are using. Not your
computer, or the components inside of it. If you are certain that you
are using a valid key Its likely that you have a a key for windows
home, and you are trying to install windows professional, or visa
versa... Either way, If all else fails, you could replace the OS (
Buy or download) much easier than the hardware inside your computer.
Basically your computer is fine, just get a valid OS. If your adventurous try ubuntu.
