I have been having a few problems so decided to reinstall windows xp (upgrade) method
Having done that i cannot update windows there are 78 updates available and each time it says “some updates could not be installed”
I have tried the stop start method renaming software distribution file SDold, but that hasnt worked
I think that using the upgrade function is very not what people should do. a complete reinstall will take a bit longer but will ensure best results and will most probably solve your problem.
this upgrade thing left many of the old files unchanged and they somehow conflict and make the update algorythm to act abnormaly. If you want to make the reinstall process easier, you can also try and use the repair function in windows setup.
