Hi Phil. . .
I would advise that you do not use any of these products. They are an absolute waste of money and they could end up corrupting your registry. Then you'll be back to see me when the BSOD epidemic begins.
The items it is flagging as "errors" are not errors at all - just entires in the registry that currently have no association to them. They hurt nothing, take up very little space and cause non-measurable time loss during boot-up when the registry is assembled from files found on your hard drive. We are talking about a fraction of a second.
600 items out of the Vista NT Registry which can easily contain 500,000 + entries represents just 0.12% of total.
To give you an example of how some of these "errors" occur - assume that you no longer have use for Microsoft Word and un-install it. A registry scanner/cleaner would then pick up anything associated with MS Word and its files, whose file extensions are .doc (≤ Word 2003) or .docx (Word 2007) files. The un-installed Word file extension relations found in the registry would still exist, but have no program to open should a doc/x file be clicked on.
I suggest that you leave the registry alone. There may be a time in the future after the installation/un-installation of hundreds of programs where this becomes necessary, but then should only be done so under the instructions of someone familiar with registry cleaners. Most important - back up the registry before using a registry cleaner via creation of a system restore point via Windows System Restore.
I myself have never cleaned the registry of a Vista system, but have done so on several years-old XP systems. It is your system and you are, of course, free to use a registry cleaner if you wish.
If you do proceed - create a system restore point -
START | type rstrui
Good Luck to you.
