Hello DaYiM.



Some programs/apps want access to protected parts of the system so they need elevated.

i didn't understand Mutex! << for which question?
& UAC is to "Never Notify", so why do i need to elevate?

Thats for the first question.

It doesn't matter if you have UAC off you still need to have Administrative Privileges to use some programs properly.

1. Because the apps werw written poorly, or not written properly for the Vista/Windows 7 model. I haven't come across this myself, but I know it is common.
2. Technically, you aren't running as an admin all the time, even if your account is an admin. It is a new method of securing the system against unintended malware installs.

thank you, & for the second question?

You have to ask the developer of those applications.

You should be able to open multiple instances of the same app, like Adobe Reader you mentioned.
