    I changed Computer Motherboard and it says I have few days (2 or 3) to activate.  I have been moving my legal copy of Windows Vista from computer to computer about 4 times.  I just replaced the motherboard to the model of intel MB and it wants me to activate again.  I am an older senior (81)and I don't need this hassel while trying to upgrade my Sister-in-Laws computer.  I finally found a person who likes Win Vista better than any OS.

    Is their anything I can do?  What is a good call in activation telephone number?  Thanks for your help!  Robert Fisher
