Accessing all directories/files in Windows Explorer

Hello Again,

I am the administrator and only "user" on my new Windows 8.1 laptop.

Two questions:

Firstly, I want full control/access to ALL the files and directories on my computer.

I've turned on "show hidden files" in the control panel but still get the access error shown on the attached image.

Secondly, how do I change from icons to details when viewing a folder? This was easy in XP but I can't seem to find the right place on W8.1

I know that the answers are out there on the WEB but it seems to take ages to search through all the results of a web search to find the relevant answer.

Maybe you could point me towards some good Windows 8.1 explanatory websites so that I don't have to keep posting here with basic questions.

​I can't even access "My Documents"

Thanks in advance,

Michael
