Re: My Documents
because, to Microsoft, the idea of separating your OS and data partitions is an unknown concept. It is the norm in Unix since around '75, and other platforms before that. Admittedly, professional Wintel admins do it, kind of, by creating a D: drive, but that is plainly not what Microsoft assumes.
I've always installed XP and XP x64 with an answer file on a floppy disk (for newer PCs, I bring along an external USB floppy drive, which also has F6 drivers on for new hardware - and that does the trick.) Documents and Settings, on any Windows PC I set up, is always on D:\.
Unfortunately, Microsoft never encouraged this or made the process practical for most end users. The Documents and Settings location should have been available with a practical default setting in the Windows installation procedure, just as it is with Solaris and Linux.
These days, you really need to prep a system before you install Windows XP or XP x64 on it, because of Microsoft's idiotic decision to start the first MBR partition on sector 63. Modern hard disks have 4K sectors, which is a bit like installing on a single-volume RAID 0 setup. But a Windows 7 OPK disc/USB key will nicely do the trick of allowing you to partition the hard disk with a 1MB offset, make it active and format it - so once you've done that, you may as well go the whole hog and prep a D:\ drive for your Documents and Settings folder.
But anyone who installs XP or XP x64 without:
a) Partitioning their hard disk with a 64K+ offset
b) Installing AHCI and/or RAID drivers via an F6 driver diskette
c) Prepping the system and storage volumes first (best with an SSD for boot, and HDD for storage)
isn't really getting the best out of their hardware, unless the hardware is ancient.
Microsoft has not made the process for c) easier for Windows 7, unfortunately - and you actually have to install the system with the Users folder on C:\ and then move it later, which seems a tad retarded. Then there's the small fact that a Windows 7 system with a Users folder on anything other than the system drive is not supported when running a service pack upgrade (although, with only one service pack projected in its entire lifetime for Windows 7, maybe that's not such a problem anymore.)
