hi how is everyone today. i'm new to the forum and not very computer smart so please bear with me. i bought a used hp pavilion running windows xp home. it was not wiped so i wanted to clean install. it came with a disc but after doing some research i found out that the product key for the disc did not match the one on the side of the case. then after using 2 key extractors discovered that the key inside the machine was different from both the cd and the lable on machine. so here is one question, if i use the cd that i got with it and it has been used to pirate with, can it come back on me? or what would be the easiest and legal way to reinstall without having to buy a new disc? can i somehow access the install files in the computer? thanks for any help. hope i did this correctly i couldn't get your search to work.
