Vista UAC (User Account Control)

On Vista, I tried to copy a zip files from a shared folder of XP, in a regular Vista folder. A dialog box showed up and say "You need permission to perform this action".

I tried to play around with UAC. I disabled it by doing:

Control Panel/User Accounts

and then "Turn User Account Control on or off". I change all the permissions of the folder. I tried to rename the file. It still didn't work. It was working with an mpeg file though.

The only way I could eventually copy this zip file was to go on XP, and copy the zip file in a shared folder of Vista, and after that, copy it in the target Vista folder.

Also, sometimes, I cannot install things on Program Files because of Vista privileges nightmare, so I created a C:\MyProgramFiles where I put stuff I cannot install to other places
