I have installed Windows 8.1 and I have provided a provisional configuration data in the installation process (ex., send private data to Microsoft, etc) and now I want to change this data but I don't know how I can do that for example accesing again to these two or three configuration windows to change the data with my new preferences. The most I get is to find a little information about some options distributed around various windows but I can't find all the configuration options to change all of them. Are there any configuration option that I can't find or some software that allows to modify this data once I have installed the operating system?. On Internet I find nothing about that.
