Don't use the guide for changing default folder locations, I use this all the time for multi hdd/partitions.
1. Once setup and at the desktop, don't bother doing any customisation, but start up Computer Management via Control Panel\System and Security\Administrative Tools.
2. Local Users And Groups\Users, select Administrator and enable the account.
3. Reboot.
4. Logon as Administrator, no password, go into normal User Account management and delete the account created during setup and any and all files.
5. Startup Regedit and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList
6. Change the ProfilesDirectory from %SystemDrive%\Users to for example D:\Users.
7. Close down regedit and reboot.
8. Logon as Administrator and create a user account with admin privileges.
9. Logoff and logon using new account and let system create profile, which is now on your D: drive which of course now the default location for all your personal files.
10. Start up Computer Management via Control Panel\System and Security\Administrative Tools.
11. Local Users And Groups\Users, select Administrator and disable the account. Leaving this enabled is a big security risk !!!
