Next time I'd do a little more planning there is no system today to avoid what happened to you.
Last time I installed a newer version of Xp I made both a disk image and and just all programs and file settings I used both Acronis True Image Home and Norton Backup plus the XP file and settings wizard
the disk image restored everything including the old operating system completely wiping out the new OS
Norton and the programs and setting wizard files restored the programs and settings but didn't save the software registration information as had to to reregister and enter the software keys alll ober Not one program retained that information
Currently restoring a new OS again and don't want a repeat of that Mistakw again
how can I be certain those licensing and registration files be stored also used the same three backup methods again
replacing the last time took several weeks.Don't want to go thru thaT nightmare again
