I don`t want to hard shutdown the PC repeatedly, why would i do that?

Your premise is erroneous. The software (the same producer as Rollback) is great for any safety needs, being backup or pure protection. Nothing is saved except for what i want to. If you use the software normally you won`t have any problems at all. Also, the OP didn`t say anything about having a SSD. So your correlations are not applicable in this case.
i know how RX works I used it since for a decade with only 4-5 several massive wreckages, but it was still one of the best tool for my job at that time .
I heavily promoted it here and did a full review and guide with several advices and warnings how to optimize its use.
My guidelines:
Rollback RX users guidelines
My Review:
Review - [Review] Rollback RX Pro v10
Sadly it fails in several important aspects, issues reported never got fixed and now other solutions are safer and more effective.
Also, RX is vulnerable if a malware compromise those 2 bootloader processes (bcdedit.exe and bcdboot.exe, if i recall well). Those must be protected if you use RX.
You ask about the shutdowns issues I mentioned, it was to replicate a power cut. I had several, on 2 occasions, it wrecked my system to the point, not even a clean install was required but a full wipe of the drive because the MBR being corrupted by RX, hence losing my OS factory restore partition.
For a soft supposed to prevent disasters this sort of situation, isn't it amusing?
Also do you seriously dismiss the SSD issue because the OP don't mention it? All modern machines use SSD... unless using an obsolete computer who use HDD as system drive those days... ? (as if you say issues with car's airbags doesn't matter because your car doesn't have any...

)
You visibly don't have as much experience with RX as me or
@shmu26 , if you had, you will not dismiss my points but mostly agree with them. Before contradicting me, please do some research. Go to RX forum, read post from dissatisfied users having huge disasters with it or those from TheRollbackFrog (probably the most experienced RX user) then you will understand what I'm saying...
RX concept is genius, even Comodo try to replicate it with Comodo Time Machine, but failed. The problem with RX is that you are playing with a bomb, as long as you don't touch the MBR or have a sudden shutdown, you are good, if not...
