How to limit the speed of access programs to the disk?

Question

Hard disks

Recently, I began to notice more often that when installing programs or when creating an area under a file in utorrent, the laptop freezes and all programs slow down.
Need a program to limit the speed of disk access, so that the speed is reserved for other programs

Answer 1

In the task manager, just lower the priority of the utorrent

Answer 2

If you think logically, then https://rubygems.org/gems/windows_ionice
will help you. If you look at the text of the question, it won’t help, you won’t be able to launch it.
So better try https://en.wikipedia.org/wiki/Process_Explorer
There you can set the process priority to "Background", then all its I / O operations will be performed last. Just keep in mind that I/O is both disk and network.
