Which one is better tool in between Iolo System Mehcanic Pro and Anvisoft cloud System Booster Pro?
Iolo is better overall. And it's known for many years.
There are users that might find these software useful. But always with
caution as these software can modify your system settings, registry and files.
Users that often install/uninstall programs, change associations, play with codec packs and audio/video tools can find themselves in situation where good registry cleaner can help ( not CCleaner's).
No one can tell you that well known software like TuneUp, Iolo, WiseCleaner, IObit, Auslogics... has just a placebo effect as they do clean your registry for programs and associations that don't exists on the system anymore, and junk files. But can not guarantee for others. You can check by counting (not manually
) your registry before and after cleaning. There's no need for system optimization software indeed, as Windows is preconfigured to do most things without these software. And can do harm to your processes and settings.
As if your habits when browsing are reckless can and will cause harm to your computer (malware infection, junk accumulation...) also, reckless using of your system offline can and will cause harm also. Just as registry cleaner software and similar,
NEVER broke my system or system of any of my customers (Wise Care 365 Free installed + CCleaner), and I find some users install 3 programs in the same time while listening the music and burning dvd, which motive is always to install games with 3 toolbars inside installer, not caring about it says "close any other programs to continue"... And when you clean their system, system broke itself. Well OF COURSE it did
Long story short, always be cautious when using this software, and it can fix something that you would never think it can.
