Uninstalling Programs/Applications

[qanda6900]

I notice that many programs and applications do not come with any uninstall file. How does one remove a program or application that they no longer want, or is not working properly.

Windows itself has a Control Panel/Add-Remove but what does a PPC have to remove programs/apps?.

Where should the program or app be installed...device or card?
Will a cab file when executed know where it needs to be put?

I am hesitant to install programs without knowing how to successfully and safely remove them.

Thanks. This PPC is very new to me. Not like a desktop for sure.
