You said, "and was able to install XP pro from my boys computer that was received from a home school company that they use".
CNET has a policy, strictly enforced, of not providing help where a "not-genuine" version of Windows XP is being used. This is because copying an Operating System for use on another computer, or using a genuine version of XP that is already in use elsewhere is illegal.
Your statement concerns me. Although you go on to say that this company had sent you an OEM version of XP I am not clear what their intention was. Was that original OEM provided for your use on your computer, or was it provided for your boys' computer?
You need to be crystal clear on this.
For years I have been able to print from networked computers in my home ( two desktops running XP pro hardwired, one laptop XP wireless and one desktop xp wireless) to my main computer thru a router. The main computer ran XP home edition for years until my hard drive crashed and left me without an operating system ( The PC is an HP pavillion and had the recovery disc partitioned on the hard drive). I installed a new hard drive and was able to install XP pro from my boys computer that was received from a home school company that they use. The company had sent me a OEM version of XP pro with all their sofware on it that were copied on blank cd's. When I initially set my main computer up again I was able to print from all my computers. I then grew tired of always logging on with a password that was setup by the home school company. Now I cannot print from any computer other than the main computer where the printer is connected.
My first question would be: Can I delete the users on my main computer that were setup by the Home school company and start my own user?
Next: Do I need a password? I would rather not have one. I only need one user account on the main computer.
If I can delete the users and passwords, should I move any or all documents out of the user I want to delete ?
Will any of this solve my problem of not printing from my networked printers?
