The disk write volume is too large. Procedure

I get 100% disk on the task manager most of the time
not only because of Microsoft edge, but the problem is also there when no app is open
my laptop is a slow one, Dell Inspiron

Processor Intel(R) Core(TM) i3-7020U CPU @ 2.30GHz 2.30 GHz
Installed RAM 4.00 GB (3.90 GB usable)
System type 64-bit operating system, x64-based processor
I do not know if this is the cause and I'm unable to solve it
