Hi,
I have Dell XPS M1530 laptop. It came shipped with Vista home premium 32bit. I want 2 install 64bit vista home premium on my laptop, so I wanted 2 know can I use my vista 32 bit license(which came with dell)? Is this legal? coz I don't want 2 do any illegal stuff.

^^no. you can't use 32-bit license for 64-bit.
