If you own a full retail copy of XP (any version) you can keep it "forever" and legally install it on a replacement machine.
OEM XP licenses "die with the hardware they are originally installed on". (legally )
WRT to "forever", owning and using a license of WfW3.11 in 2008 is proof that immortality might not be all it's cracked up to be.
