1) From what I read, the MSI Cleanup Utility is only
for removing Microsoft and Windows applications such as Office Suites and parts of them (to the exception of Office 2K7), if normal removal methods have already been taken, and you want to remove the registry entries. It will not remove or list 3rd party application registry entries. Only a 3rd party registry cleaner will provide this (jv16, RegSeeker).2) From my present and previous dealings with 3rd party reg cleaners, it's not so much on which one you use, but how
you use it. Caution must always be used before selecting that "remove" button ! As Liz mentions, err on the side of caution, and create a manual restore point
before using a registry cleaner the 1st time (even though it may create a backup of it's own). The one thing I like about RegSeeker
's latest build, is that it automatically creates a file with the name of the search word appended to it. 3) Just prior to using RS, I had jv16
as my tool of choice. Unless you can find a free "old version", it's now shareware, and the reason for my move to RS. And it's far from being a user-friendly app. It's probably the most powerful (and thus, most dangerous one to use potentially) if you don't screen your entries before pulling the "trigger". Again, that restore point...
is another great tool, but geared more toward removing temp files than being a dedicated reg cleaner. It does have an "Issues" button. But much of what it will pick up in that scan are changes that were intentionally done by an advanced user, and "fixing" those blindly will result in either having to do the custom changes all over again, or in the worst case, rendering shortcuts unusable. I prefer to stay away from that button in CC, and use the "Clean the registry" button in RegSeeker, and sticking with the green entries for removal. Again, have a backup plan...I've also used ToniArts' Easy Cleaner
in the past. But it's been so long, I can't make any comments because the build may have changed several times since.With any of these tools, it's always a case of YMMV...
