Fresh Windows 10 very slow ?

[nf24eg]

few years ago I upgraded from windows 7 pro to Windows 10 pro on my laptop.
everything was very well and Booting time wasn't exceeding 15 seconds to land on desktop.
The laptop was loaded with heavy softwares and was running very smooth and not slow at all

for safety issues, I re-installed windows 10 (directly without windows 7 and then upgrade)
even without installing all the softwares I use as before the laptop takes more than 2 minutes to boot and about 1 one more minute to load programs.

opening and closing programs takes time and very slow, also shutdown takes long time.

laptop HP 4540s
Windows 10 Pro 46
i7-3740QM CPU
12GB Ram
SSD WD 1000GB Blue

I reinstalled Windows twice but still same issue.

12gb of ram? How does that work?
I assume its 16gb and shares ram with gpu

have you run this and confirmed you have all the drivers?

Ram = 4+8
I've tried the HP assistant and all drivers are up to date

I downloaded the WD SSD Dashboard Diagnostic program and initiate the TRIM and that made things go faster

I think that was the issue (Till now)

many thanks for your support
