[mdt] Refresh scenario disk space required?

[gshaw]

I'm just tweaking our Windows 10 Task Sequences at present and trying out the "Refresh" scenario for installing the new OS i.e. launch MDT from inside an existing Windows environment.

 

This is nice and easy for our technicians as I've attached the LiteTouch script to auto launch on a dedicated service account so in theory all that's required to image a machine is to log in with a specific account and away you go.

 

The only thing is some of our Windows 7 machines have filled their 60GB SSD drives up with updates etc. so I'm wondering what the minimum space required for the Refresh scenario to work is and whether MDT checks for this itself before starting the TS?

 

I already have a custom VBScript that runs before launching LiteTouch to make sure the machine isn't connected on a slow (100Mb) link so I could easily add an extra check in there. Have read somewhere about 6GB being required but that was just off the back of a forum post I think. Anyone got any experiences of using Refresh and how well it worked?
