Ok, I have looked in the Intel documentation
for the FXSAVE operation:
"Saves the current state of the x87 FPU, MMX technology, XMM, and MXCSR registers
to a 512-byte memory location specified in the destination operand."
Thus means, every thing is fine and I can used the XMM registers without risk.
Thanks for the support.
