Can the stand-alone version of Windows XP Pro be used to
upgrage an already installed version of XP Home?
That depends on what you mean by "stand-alone."
There are three kinds of CDs you can buy. There are the Full and
Upgrade versions (both of which can be used to upgrade) and the
OEM version (which can not do upgrades).
Are you sure you want to do this? Are you aware that XP Home and
Professional are identical except that Professional includes a
few features (mostly related to security and networking) missing
from Home? Most home users don't need and would never use these
extra features and will see no benefits by upgrading.
