1.) The person that wiped your computer not only used his/her CD, but also his/her product key, which isn't legal.
2.) Normally you could simply change the Product Key, but that's most likely not a possibility for you. The reason is that you have an OEM version of Windows, while it sounds like the person that installed his/her copy has a retail version of XP Pro. The changing of the product key only works if you both have the same version of Windows, which isn't the case here.
3.) Modern PCs usually don't come with a Windows or Recovery CD anymore, but instead a recovery partition from which you can burn your own CD. That is the recommended first action after turning the PC on out of the box. Unfortunately you can't create a CD now since the hard drive's been reformatted.
4.) Your only option is to contact the manufacturer (HP) and order a recovery CD for your computer. They will charge you a nominal fee, plus shipping and handling.
5.) There is likely a time limit on this...Windows will most likely cease to function in less than a month, so don't delay.
6.) If you are unable to obtain a set of recovery CDs from HP, you'll have to purchase a new copy of Windows XP. It can be either retail or OEM, but it cannot be an upgrader's CD, since that requires that you have a legitimate copy of a previous version of Windows.
7.) Be sure to thank the person who did you the favor!
I had my computer wiped out and the person that wiped it out used their windows pro cd to reinstall windows into my computer to make it run. Now I am getting a "warning your windows program may not be genuine, to buy a genuine program click on this link." It has a star that sits in the lower right hand corner of the desktop by the clock.
I bought my computer new a couple years ago and the windows program came with it but with no cd. I have my serial number for the computer and windows product key, but I cant figure out how to get a new cd using my product number with my hp registration. I'm afraid the computer is going to shut down soon if I dont figure out what to do. Thank you so much for any help you can give me.
