下載 xpmode？

XP mode is just a Virtual Machine with Windows XP pre-installed, so if you can't download XP mode for whatever reason, just ignore it and use another VM.

In fact, XP mode can't performs as good as other VM solution outside, say VirtualBox (which is Open Source) and VMware (which have some free of charge version).

Of cause you need a copy of XP in this case, the only benefit of XP mode is a free XP licence, but it is totally useless if you have got one already.

Just an additional note, XP mode doesn't have GPU acceleration support at all (which makes it totally useless when trying to run 3D applications, games, etc), where VirtualBox and VMware both have (although still not perfect).
