Background:
I've been given an ex-company PC with XP Pro already
installed but no disks. I want to buy and install an
official copy of XP (preferably Home, I don't really need
Pro so cheaper option is better for me).

Here is my dilemma:
The version of XP Pro already on the PC has possibly
suffered some registry damage (no toolbar, no desktop and
Explorer and IE won't start although certain programs can
still be run from Task Manager browse). I would like if
possible to preserve some of the programs/data already on
PC when new OS is installed. I assume that my only route
is to buy either Home Full Version or Pro Full version.
Will Home install over Pro and can I avoid Losing
everything already installed??
 
No, you cannot install Windows XP Home Edition over
an existing Windows XP Pro installation. You'll need to
purchase a "Full Version" of XP Home and perform a
"clean install".

The Windows XP CD is bootable and contains all the tools necessary
to partition and format your drive. Follow this procedure and allow
Windows XP to partition and format your drive:

NOTE: It would be best to physically disconnect all your peripheral hardware
devices, except the monitor, mouse and keyboard, before installing XP.

NOTE: If you have an internal Zip Drive installed, physically disconnect the
EIDE and power cable to it before proceeding, otherwise your main
hard drive may not be assigned the customary C: drive letter.
After installing Windows XP, you may then reconnect it.

1. Open your BIOS and set your "CD Drive as the first bootable device".

2. Insert your Windows XP CD in the CD Drive and reboot your computer.
3. You'll see a message to boot to the CD....follow the instructions.
4. The setup menu will appear and you should elect to delete all the existing
Windows partitions, then create a new partition, then format the primary
partition (preferably NTFS) and proceed to install Windows XP.

7. After Windows XP is installed, visit the Windows Update website
and download the available "Critical Updates".

8. After installing the critical updates, be sure and visit the support website
of the manufacturer of the computer to download and install any
available Windows XP compatible drivers, such as video adapter
and audio drivers.

9. If you happen to run into any installation difficulties, use the following resources:

then select the option to "activate by telephone".

Thanks for quick response. What if I bought XP Pro Full
Version. Would I be able to do a "repair" install rather
than clean even though the XP CD Key would not tally with
that already installed?? My objective is to try and
retain some of the existing programs/data if at all
possible.
Thanks

Yes, using a "Full Version" of XP Pro and performing
a "Repair Install" will preserve the programs.

Greetings --

The only way to change from WinXP Pro to WinXP Home is to format
the drive and start over. There is no supported downgrade path or
technique. In order to do this, you must have the WinXP Home
installation CD.

Simply boot from the WinXP Home installation CD. You'll be
offered the opportunity to delete, create, and format partitions as
part of the installation process. (You may need to re-arrange the
order of boot devices in the PC's BIOS to boot from the CD.)
