I am very sceptical about purchasing registry repair tools as I've seen reports on the Internet where some of the companies involved take your Pay Pal data for a free trial and then bill you on a yearly basis and it's difficult to cancel, for example, as one of these companies is in China.
The other thing that concerns me is that anything that gets into your registry can wreck havoc if it's not legitimate and universally well received.
On the other hand, I would suspect that over time, the registry gets corrupted to some degree and needs repair.
Are there legitimate registry repair tools out there from reputable companies or is the whole subject scam bait? I have seen a free repair tool posted on CNET called Free Windows Registry Repair and would think recommendations from CNET would be above board but don't know enough about this to make a decision plus any bad decision here could have very bad results.
What would you advise?
