Vista Tutorial - I give myself "permission"!

I am the administrator, I am the owner, and I know what I am doing to MY computer. I would like to know how I can gain control of MY computer and not be told that I can't do things to MY computer because I don't have permission from it! It's like it's telling ME what not to do like a little child back talking to it's mother!

I get errors like "You do not have permission to do this action" or "Permission Denied" or "Wah! I'm a little brat and am throwing a tantrum!"

The problem started when I was trying to uninstall a program called Shopper Reaports that is not listed under the control pannel to uninstall. I tried to use a PC Decrapifier that has helped me out in situations like this before but even that program can't seem to uninstall Shopper Reaports. So, I found the file in Program Files and tried to delete it and the above senerio happened. Any advice or maybe a reply with some sympathy venting would be nice! Thanks in advance!
