Richard,
It doesn't sound right to me.
You said you did a clean install.
Did you format the HDD before reinstalling XP?
Look in Add or Remove Programs and see if there is an option to uninstall XP.
Or is SP1 listed there for uninstall?
Is this file on the root of the C Drive or in a folder?
Is it a hidden file which will not show if you check the option in Folder Options | View.
After doing a clean install On my 1.60 gigahertz AMD Athlon XP I noticed a New file that I don't remember seeing before:
30803d2c2188feaa151392 contents; contains files that remove XP and restore your previous configuration.
Am I right in assuming that these would be used to restore XP if I was to remove SP1 and as such can be removed.
