Depends on the tool and how you use it. I use SystemSuite that gives
registry scan results in a color coded list, green, safe to remove,
yellow, maybe safe to remove and red, you better know what you're doing.
Systemsuite provides a way to make a floppy to restore your system if
removing an entry makes the computer unbootable and you can restore
any entries with the program itself if it does boot.
That's the point. If the system doesn't start anymore after "cleaning"
the registry, the cause is rather clear and what a lucky guy if his tool
allows for system restore while Windows cannot be accessed. In cases
when cleaning the registry "successfully", the majority of the resulting
problems will show up at a later date and the user will never ever come
to the conclusion that this problem has been caused by the registry
cleaner. Even in the remote case that he does, using an out-dated "Undo"
file may mess up the registry furthermore.
I have had SystemSuite since 2001 and have never, ever, had a problem
with it and I have deleted thousands of registry entries with it on
many machines using 98/Me/W2K and XP.
Well, you never had a problem showing up instantly (see above). A good
example has been the EasyCleaner prior to version 2.0 IIRC, destroying
the function of WinMe's and WinXP's Help&Support Center. Never-ending
postings at that time complaining about that problem and absolutely no
user capability to detect the relation to that useless and harmful tool.
Maybe you want a clogged computer but I don't.
LOL! Note that the registry is not a sequential database. Turning
orphaned registry entries into slack space cannot really speed up your
system unless you strongly believe in it (placebo effect).
