Hi
Have you turned off the UAC?
I'm guessing that most of the people here have it turned off, if for no other reason then to get rid of all the annoying messages.
There isn't really a lot of risk if you are the only person using your computer.
You will find that Windows gets a lot more trusting with it off.
It was driving me crazy when I first installed Windows 8.
Now I'm using my regular Administrator Account and it leaves me alone. LOL

Ps. you should also be able to change the attributes of all the files in a folder from the folder properties.
Uncheck read only etc, for all files in the folder.
