ACR and PS: Can i have them on the desktop?

There are probably other ways to do this. In Windows, this is how you would do it. If you're on a Mac it would probably be similar.

Using Windows Explorer, open the Program Files folder and then the Adobe folder.

Next, open the Photoshop 2020 folder.

Next, scroll until you find the Photoshop.exe (or whatever the main program file is on the Mac)

Right-click on it and choose to create a shortcut.

You will receive a message that it cannot be created there, but will be asked if you want to put it on the desktop.

Agree to do that, and the shortcut will be placed on the desktop.

Camera Raw is a plug-in, and as such cannot be placed as a shortcut. You could access it from Bridge and have Bridge on the desktop by following a similar procedure.

Another way to do it in Windows. While Photoshop is open and on the taskbar, right-click on it and choose the option to pin to start menu. Then go to the start menu and drag it to the desktop. Then, if you want, you can delete it from the start menu.
