Why my Matlab 2017a is so slow for even simple commands?

Hi there,
I got a new computer and installed Matlab 2017a. The computer looks pretty good with other softwares as it has 16GB of RAM and an AMD 10 processor with Windows 10 (not a fan of it). What may be causing such laziness in my Matlab? I checked the task manager and I see that the processor is not heavily demanded (Matlab and Chrome takes, each, around 3% only and all the other applications use less).

Thank you very much for your rapidity Jan and for the contributions of the other colleagues!! : )
First of all I would like to apologize for not answering earlier but even having this thread as 'followed' and the 'email notifications' checked I didnt received any mail (not even in Spam). Not sure if the reason is that I 'commented' and not 'asked' nor 'answered'.
I am not an expert in computer science but i will try to answer your questions Jan:
JAN- "it does not let me connect to verify license".
It seems I got lucky and after 2 days trying to install it it has finally connected (nothing changed in my side: same PC, same connection...). I have installed R2016b and the behavior is the same, my PC is in 3rd position when booting the PC:
bench = 0.19 0.16 0.06 012 0.51 0.66
and in 7th place after my PC has been started for some seconds:
bench = 0.37 0.50 0.23 0.40 1.11 1.31
The only difference is that, as you mentioned, bench in R2016b seems quicker in general terms than in later versions (compare vs my bench results in the previous comment with R2018b).
JAN- Did you check the temperature of your CPU?
I hadnt because I hadnt notice anything. I have checked the temperature and stays at common levels (comparing to other times when I checked it a couple of years ago) of c. 50-60 Cdeg (even in warm Madrid at 40 Cdeg : P).
JAN- What does "I found a registry regarding R2015b" mean?
Sorry for the inaccuracy, I didn't want to give further details as I (probably mistakenly) though it had no relevance. It was a "REG_SZ" registry in the folder "Layers" that the colleague in the other thread mentioned. I can no give more info since I removed it.
JAN- Which "Compatibility mode"?
The one that is activated via Right click->Properties->Compatibility-Run this program in compatibility mode for "Windows 8".
JAN- Did you run a virus check to look for trojans which calculate bitcoins?
I think that is not the problem since CPU is at c. 1% in idle.
JAN- What does "CPU and RAM performance also stay at low levels" mean?
I meant that CPU stays at c. 1% and RAM at about 4GB (25%) in idle. I mean, it seems there is no a "strange" process running behind that can slow down Matlab externally.
JAN- this is not a Matlab problem, doesn't it?
That's what I'd love to know haha The fact is that it doesn't seem to happen with other programs (e.g. Excel VBA macros), as @Hugh has experienced also.
Hope this can help us find the solution. Thank you very much again for your interest and help @Jan, @Hugh and @Steven! (in this and several other questions that have helped us in this forum before!)
PS: Please @Hugh, let us know if you find a solution with the support team.

Try this command...
opengl('save','software')
and restart Matlab.

Same to me. It is terrible when to run stuff. Everything is slow even the MATLAB website feels slow.

Same to me, came from 2016b to 2017b and my code runs 3x slower thand before. Any tricks I should know?

double check if your pc is running in boosting. Or artificially enable turbo boost when running MATLAB.
