I'm sharing a windows 7 machine with someone. I plan to install programs as well as copy files there that I do not want her to have access to.
In the ideal case, what I need to be hidden is completely invisible, and there is no way for her to know that such files/apps exist on the machine.
We're not going to use separate users (don't ask...), even though that's the use case that that feature was created for.
In my imaginary world, when she opens the computer, my programs and files cannot be found. Then when I use it, I can enter something into cmd and bring back access. Another command to hide again. :)
Edit: I should mention that it doesn't have to work this way, anything that gets me what I basically need is welcomed.
