@cooldude75ph: Bro, I'm not trying to bypass the OS protection. I'm trying to get help on where I could enter the CD key field again.
I was able to install it the 2nd time around with no hassles but this problem happened after 3 weeks of using the OS. And to think of it, no internet connection pa akong PC. Even my friends were puzzled so refer ko to istorya for some enlightenment.
My 2nd to last option is to try reinstalling the OS if I can't find help on where to re-input the CD key. Thanks for the tip airosus.
Last option would be to reformat the C:\ drive again as what karen & jintatsu suggested.
Any other way to re-input the CD key before I execute these options?
