Here the features that are present in WinXP Professional but not in WinXP
Home:
- Remote desktop
- Domain validation
- EFS (Encryption File System)
- Device driver rollback, last known configuration, system rollback
- IIS
- Multiple CPUs
- Multiple language support
- Dynamic disks
As you see, none of them refer to partition recognition. Upgrade/Full
Version does not matter either. There is something else that is lurking on
your machine. Is your WinXP Pro a legitimate version?
