I had lost Microsoft Product Activation key,still I have serial number.Help me
Call up Microsoft and tell them what the deal is.
I assume you own a legit copy of XP, and if you do then calling them will be no issue. Its even toll free I think.
If you have a pirated version, you have came to the wrong place for help on that, but out of good faith I think you don't have a pirated version. In which case call up Microsoft and they will be very helpful on telling you what to do.
I was skeptical of MS's product activation hassles when I finally got a legit copy of server 2003... We had to put it on not one, but TWO temp servers before moving to the final one.
We all know the horror stories of large company phone support... well, I called them twice for the reactivation (transferal of license) to a different machine. Longest phone call was 6 minutes, 3 seconds. That's not bad, my friends.
Not to mention, venki, if this is the same physical machine compared to the last time you activated it, you can activate again over the internet no hassles.
