I am terrible at understanding permissions?

[flycaster]

When I log on, I am being logged on as an administrator. Going to Properties for just about all my programs, Security looks like this:

With System being the selected in all instances.

I am at a loss as what this means. That is, should I leave it at Systems or change it to one of the other choices. What is the difference between these three choices? If I change to another choice, will I still be denied Permission when conducting certain activities (like I some times get denied when wanting to change a file, or move a file, etc)?

What are listed on that window are not options, it is a list. System, Adam&Carol, and Administrators are considered users or groups on your computer. As you click each one, it says what that user or group can do with the file and/or program you are looking at the properties of.

Hello flycaster,

I would leave the System permission as it is. You have to be very careful when messing around with permissions, in extreme cases you could leave your files/drive inaccessible and windows not being able to boot.

Never use the deny option unless you have a specific user you want to hide files from (children for example).

Thanks all, got a better understanding now. However, before i ever try to change something, I'll be sure to check it out with the forum.
