I'm not sure all of these types of programs are scams but I've never used one.
I wouldn't think so, then that's why there're places to find
guinea-pig if not normal reviews. Not that normal reviews are exactly
normative when it comes to Microsoft's registry;- it's linked,
potentially, into proprietary Level-1 OS kernels, hence known among a
specialty, you're after, fraught with disclaimers - such as: 'Use at
your own risk.'
When did you last ask yourself why, indeed, wouldn't Microsoft provide
such tools for modifying its operating system. . .
Again, that needn't discredit honest reviewers -- even 'hackers' with
ulterior motives other than Bill Gates' reoccurring dream of
Informational World Domination -- from offering free, (sic) token
registry hacks;- hence, in roundabout ways, regarding relative
assessment, lending to the dubious distinction you affect if too ready
with "blanketing" statements as scams, industrial copyrightists, in
fact, readily might deploy among types of clandestine conditioning,
entrepreneurialism, and its dominant forms of expression over
economic/political sovereignty.
In the world, of course, as we live it;- if you don't like it, the way
it is, I hear Uranus may be more accommodating for relocation.
