We were using deepfreeze before on public access computers. I have public computers in intune with intune and office 365 device licenses applied. We have a Kaseya so after the autopilot setup is complete a procedure is used to configure and enable the UWF. If you wanted to use intune to enable UWF I would create an app that would run a PowerShell script that would enable it. add the computer config group to the app after the computer has finished configuring. I use intune to create a local account named public access on each of the public computers. Software called PC booking is used so Library patrons can use their library card and pin to access the computers.
Unified write filter has a servicing mode that is automatically supposed to perform the windows updates, this servicing mode does not work with the pc booking software we use. I have a window on Thursday mornings where the bios wakes the computers up and then a script that runs every 15 minutes in the background checks if the computer is in the windows update window or not and then disables the write filter if it is in the windows update window. I have been having problems still with the updates, sometimes with the restart command the computers shutdown instead. I am getting close to making UWF an alternative over deepfreeze but it has been a bit of work.
