Where Does PowerISO Store Settings?
PowerISO keeps settings in the registry with virtual drive state, while ISO files stay wherever you saved them.
Last updated
PowerISO stores options, recent files and virtual drive assignments in the Windows registry rather than config files. ISO images themselves live wherever you placed them.
That split means there is no settings file to copy. Migration runs through registry export of the vendor branch, while images move like ordinary files with no buddy data attached.
Where PowerISO stores this, by platform
HKCU\Software\PowerISO
Options and recent file lists. Virtual drive letters reassign on reinstall. Export the branch to migrate settings between machines.
