In need of Unmanaged SEP client Script

Hi,

I have loads of unmanaged SEP clients in my network and i would like a efficient way to make them managed. I had planned of your unmanaged detector and then trigger a unmanaged notification and select to run a batchor script the challenges i am facing are

1) All unmanaged PC's do not have the same SEP version client but of different versions ranging from 12.1.1 - 12.1.5

2) Different smc start stop password

3) Some do not have password for stop start but have for import and export sylink

With all this in place i am not able to script anything effective to tackle unmanaged PC's and the number is too many that if i choose the manual method it burns days together.

Environment: Windows 7 and windows XP PC's

SEPM version: 12.1.5
