Does anyone have any experience with a good tune-up utility for an Inspiron 8600.

I downloaded a utility named TuneUp Utilities Startoberflache. I have it in trial version.

It seems to do everything that anyone would want. It found numerous errors and problems with my registry, and offered to fix them. It gives control over what starts and what doesn't. It also monitors memory usage.

What seems too good to be true often is.

After running the software in trial mode, and allowing it to fix my registry and tune up my memory, three of my most important programs (including DeLorme Street Atlas) just refused to work. They had to be reloaded.

Also, my boot-up time is now about two minutes while the computer sits on the "Welcome" screen of Windows XP Pro while it thinks and thinks and thinks.

I would appreciate any feedback on this specific software, this subject, and how to reverse any damage without formatting the hard drive and starting over.
