Creator does alter the ASPI layer- latest versions install 4.7X without notice. The ral nightmare is the uninstalling part of it...
Still Creator is not the worst program out there- just POOR software with a lot of useless and sort-of-working fireworks.
I'm biased against system restore... under ME it was just crap, sometimes working sometimes not and offering a big performance handicap. Gladly enough it can be disabled with third party software.
Under XP the performance handicap is minimal, and most times it works (not always). But I cannot see any good reason devoting several HD gigabutes to something that
might work, since Ghost and True Image work 99,5% of the times, and the snapshots can be stored to cheapo CD/DVD media instead of my HD.
I won't like to comment on "Go Back", porn is not allowed in this forum!
