. . .
in the part "C:\windows \ system32" When I enter the order CD no things happen i it open a new line without move to the part"C:\windows "
In my understanding, you are currently in this directory: C:\windows \ system32. Using
CD command means you want to go back from the system32 directory down to
Windows.
Use this command instead: cd..
Look here:

As you can see in the figure, the cd command does not do anything, but the
cd.. command will let you go back to the previous directory which is Windows.
Regarding this query:
. . .
and also i have a big problem sometime when i enter order i received a message "System can't find the path specified "
Let me know which command /order do you use here.
Feel free to keep us informed.
