I don't like any Iobit software, especially if it includes a driver updating function as they often make things worse
Most of the time you don't need programs like this, Windows 10 can look after itself pretty well now. System clean up not really much help.
much of what it does is run built in win 10 features. replaces them, or fights against them
Features:
Scans & Cleans system logs, temp files
Disk cleanup does that now, as does Storage Sense.
Security/ Anti Virus protection/Firewall
Defender is free and is probably just as good
efficient ram: Release RAM from background programs
That feature right there is fighting memory management as win 10 compresses things into ram and if something is removing those things to "free" the ram it can actually slow PC down as it has to look on page file for that info that was in ram before. Free ram doesn't help PC
Maximise Internet Speed: Bandwidth Prioritization
I doubt this helps a great deal.
Faster Startup: Block Programs from starting Auto
You can do this now. You can go to start tab of task manager or use a program called Autoruns from Microsoft -

Or just look in options for the programs as most let you disable auto start.
Stabilize Windows: Deep cleaning of your PC's registry
Registry cleanup really doesn't help
