Start each Windows Explorer window in a separate process

By default, even with Windows 10 , Windows Explorer always starts in the same process . So if you have 5 or 10 Windows Explorer windows open, only 1 Windows process is open as a basis . The advantage of this is, of course, that this one process takes up much less main memory than if each individual Windows Explorer window is a separate process.

Nevertheless, starting each folder window in its own process can have advantages . For example, if there are problems with the Explorer and it crashes, all Explorer windows are usually closed. However, if you have set Windows Explorer so that each folder window starts in its own Windows process , this problem does not arise.

Setting in the folder options

To change this, you only have to select the ” Folder options ” item in Windows Explorer under ” View ” and then switch to the ” View ” tab . After that very your next picture.
