I’m very skeptical about registry cleaners in this day and age. Unless things are severely messed up, doubtful that any meaningful difference will be realized.
That said, I ran the program through the system optimizations, registry fix, defragmentation.
This resulted in a significant improvement in boot time on two computers, one going from 750 seconds down to 160 seconds, and the other with similar results.
This company has always had good products. No hassle download and installation. Can fully recommend to grab their registry cleaner before the “sale” ends.
