Alternate Explorer Shell

Can someone explain how to set up the alternate explorer shell? I’m not finding any info on it. I’m running the SCCM console as a different user and get prompted for credentials when connecting to a C$ share via RCT. The user I’m running the console with is a domain admin and does have access. The description of this setting does seem to point to this situation.

You can configure it in the Windows Explorer tab of Configure Recast RCT.

I’ve tested it with Explorer++ and it seems to work well: https://explorerplusplus.com/download

Thanks Chris, that works great.
