Greg, do you have any experience of problems on a number of Windows 7 machines on which you did not install third-party registry tools? I mean, I only have one desktop running Windows 7 so far, and my experience is nearly perfect, and I am not using any such tools. I do install and uninstall programs rather often, although not daily, other than that, what is there to make problems with the registry? What are the symptoms of such problems?
Come to think of it, I have not even performed a hard drive defrag, since any defragger I use, native or Auslogics, tells me that my drives are 1% fragmented, not much sense of doing anything so far, and it's been more than a year.
