Does CCleaner clean open applications when it is run by script or command line?

I use Macrium Reflect 8 to back up my system. I have included the following command at the beginning the VB Script that runs one of my backup jobs:

“”objShell.Run """C:\Program Files\CCleaner\CCleaner64.exe"" /auto"

That is, CCleaner is run before the actual backup starts. My question is, when CCleaner is run in this way (or by command line), how does it treat applications, such as a browser, that may be open when the command is run? Does it actually clean such open applications or skip them? (I note that when CClearner is run “normally” and an application that it is set to clean, such as a browser, is open, it will offer the user the option of shutting that application down.)

auto skips open as far as I know, it runs custom clean and auto skips those open browsers et al

Thanks for that. I was pretty sure that was the case but thought I would seek confirmation -- just to be sure.
