Removing network access

Solution
It needs to be done from the computer on which the folder is located. Simply go to advanced sharing options in the properties menu of that folder and remove access from your user name.
I'm pretty sure that has nothing to do with network shared folders. But in general, as long as your PC is on the same network (or homegroup) as the other one you will be able to see it and access it.
 


do u know how to block access to it?
