I bought the OEm XP SP2 Home CD from new egg a while back. I installed it on my main rig, it crashed once in 3 years so I installed it again. Now it crashed again and I want to install an activate one last time for a Win 7 upgrade. Now the problem is I want to use this OEM CD to install on an old laptop. I don't think I can activate 3 time so I downloaded the GenuineXP.rar from a post here. This allows me to get updates but I keep getting an error message on trying to install SP3. This laptop will not be connected to the internet and just used as a music server so I don't know that SP3 is important to have or not? Any ideas on what to do ?
