Support Assist for business PC's - more information about the different elements

So.... here I am preparing the installation of support assist our company PC's and as I'm looking at the installation I miss some information.

Once installed is see six different elements;

• Get Drivers & Downloads - Disabled at the moment, Dell command update is being used since we have BitLocker in our environment and this function doesn't support that at the moment.
• Scan Hardware - Where can I find more information about this step, what's being scanned and what corrective actions are taken and is there a detailed log? 
• Clean Files - where can I find more information about this step, what files are being removed and is there a detailed log?
• Tune Performance - where can I find more information about this step, how is performance being managed?
• Optimize Network - where can I find more information about this step, how is the optimizing being carried out?
• Remove Viruses & Malware - Where can I find mode information about this step, what engine is being used? is it only done when initiated or is there a "Dell" antivirus client running?
