I just upgraded to SSD and added a ram and everything is working as I expected
This is a cheap laptop for what it can do so I really should have expected this.
the 100% disk may be an issue of RAM is full as well. Not enough RAM will write at the disk.
I know this because when I upgraded my RAM and SSD, i did not reinstall a windows yet.
I was using the laptop for 1 day and the laptop got faster.
When I installed a new windows, yes a new windows without those acer bloatware, everything is now as I want it to be
