I have XP Home edition and don't want to spend the money on XP Pro until I
know that it will upgrade and I won't have to reformat. Can XP Home be
upgraded to XP Pro?
Certainly. WinXP is designed to install and upgrade the existing
operating system while simultaneously preserving your applications and
data, and translating as many personalized settings as possible. The
process is designed to be, and normally is, quite painless. That said,
things can go wrong, in a small number of cases. If your data is at all
important to you, back it up before proceeding.
The upgrade from WinXP Home to WinXP Pro, in particular, almost
always goes smoothly, as both operating systems use the same kernel.
However, do you really need to upgrade? The WinXP Home and WinXP Pro
versions are _identical_ when it comes to performance, stability, and
device driver and software application compatibility, but are intended
to meet different functionality, networking, security, and ease-of-use
needs, in different environments. The most significant differences are
that WinXP Pro allows up to 10 simultaneous inbound network connections
while WinXP Home only allows only 5, WinXP Pro is designed to join a
Microsoft domain while WinXP Home cannot, and only WinXP Pro supports
file encryption and IIS. (Oh, and WinXP Pro usually costs roughly $100
USD more than WinXP Home.)
