On Windows, none of them are first party software.

And of course you conveniently didn't read where it supports basically everything else through third party software.

Data could also be viewed and/or manipulated using other third party software.

It attempts to remove third party software that may have caused the system to run slowly.

The big concern for me is lack of good first party software.

It is extendible to allow integration into 3rd party software.

There is also third party software that provides this feature for various operating systems.

If fully animated backgrounds are wanted, third party software would need to be installed.

For other systems, a third party software is required (* in development).

It took less than two minutes & I didn't have to negotiate any third party software.
