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 you recently changed or added hardware like some new CD or DVD devices, that could happen, or you simply have a pirated version of the operating system. Depending on your circumstances, if you can substantiate that you purchased the computer or operating system legally, you can contact Microsoft and you may be able to get them to sell you a valid key.
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.
What OS does your new computer have? What was your old OS? Unfortunately, install codes do change with OS versions and a program for a much older program will not run on a new OS (esp for Microsoft products). This program (in its English Windows version) was coded to run under Win95-WinXP; it probably can't run under Win7. You can try installing in the compatibility mode (for Windows - right click on the installer and select properties and the compatibility tab). However, this doesn't always work. It isn't a program listed in the Windows Compatibility Center for Vista or Win7 (although the Vista version is confused with its search results - 47 items found becomes 11).
Another option is to install an OS that will run the program as inside a Virtual PC program or as a dual-boot option. (Win7 Pro and Ultimate allows you to install XP mode free (a virtual XP computer after you download and install two programs from Microsoft).) Otherwise you will need a valid licensed copy of the OS you need.
There may be a workaround or two. First, Win7 wants a different installer. Try running the installer in a Compatability mode (right click on the exe, choose properties, click on the Compatability tab and put a check in the box for run this program in the compatability mode, use the drop down to choose the latest OS that you know will run the program, then right click again on the program and choose run as administrator). If your new computer uses 64-bit Win7, this is even less likely to work. Microsoft needs signed files in 64-bit. Do the same compatability with the program if it installs.
If that doesn't work, try installing a virtual computer with an OS that runs the program in your Win7 machine (The free XP mode is available in Win7 Pro and Ultimate. It takes two downloads from Microsoft to install the computer and then install the program as if the XP mode was the only computer.)
Otherwise, upgrade the program. (The Microsoft compatability center gives information pending on the program.)

Bypass all Windows Genuine Advantage validation - Windows...
Haklabs has posted an 8-step solution you can use to bypassthe annoying Windows Genuine Advantage (WGA) validation process for any Microsoft product installation ...lifehacker.com/software/microsoft/bypass-all-windows-genuine-advantage-validation... - 63k
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.
