text: does anyone know why  my computer is failing to install  microsoft windows updates for xp? they download but do not install when i check my update history there is a red cross with failed next to it. it has been going on for about 2 weeks please help!!!! you must have an original windows. i mean you can’t install xp on two different computers. microsoft is checking the hardware on your pc, when it’s not the same as the first configuration then it won’t allow updates, security’s updates are allowed. when you pay for it? check the number from xp it’s all correct? then make contact with www.microsoft.com they must have the solution.
