Yes my question is quite simple I presume but I am battling for ages to setup a true Admin account that will allow me to change all the access and parameters on my Acer Laptop running W10 Fall Creator Update right now. For example, I would like to rename a program in the Program Files folder and it just do not allow it.
Many thanks,
