Win10 like win 8.1 wont let major changes or much else be done by the little man. You got to be boss for most things, I normally go into preferences on the program shorts etc and set them to run as administrator. I think MS tried to make 8.1 and win10 more like old NT4 systems, dosnt work the same but the principle is the same. In a way its very much like a poor mans network administrator, except with the newer OS from MS companies can employ less intelligent people to run the networks.
Also seems to like to make it hard to stop people being discrete, MS seems to want to know alot about what your doing with YOUR machine. But then again you dont own the operating system anymore, you pay to use it, and use it on their terms.
