The reason why my sister and I took the service pack update off is because somebody at my sister's work that is one of the lead computer people there said that he had that problem and his computer and several other computers. When he took it off it fixed it. Should we put it back on or should we leave it off? My sister's computer is still working just fine.
Many things, online are off, are going to be problems!
For the majority of cases, Keep XP SP3 unless it did cause a problem.
