Winferno registry power cleaner etc.

hi
have just purchased winferno registry power cleaner,and is expecting a lot from this software,since it is a mcafee product,or anyway i have bourght it on their site along with 4 other utilities,does anyone have any experiense with mcafee utilities in general.
the reason for the purchase is that i for a while now,have had security from mcafee in form of total protection 2011-2012 and and all acces,onlie backup and god knows what.Expensive yes but efficient oh yes,it has saved my system many times when i surf on risky sites.It is not a secret that i am very pleased and impressed with mcafee in general,and i would recomend it to anyone without ecseptions.
ps my spellig and gramma is very bad sorry.
Kind Regards Asser

@asser:

You will find that almost all of the Windows 7 experts around here and even MS itself advise AGAINST using registry cleaners unless you are an expert user yourself.

Unlike older versions of Windows up to XP Vista and 7 do not see improvements in performance when you clean the registry, even worse because of the more complex registry key sharing used now what might appear to be unneeded may still be required and this could lead to your OS not even booting at all.

I'd wouldn't use ANY registry cleaning tool unless you get expert help.
