#StackBounty: #windows #windows-10 #permissions #uwf #uwfmgr UwfServicingMasterScript can not be edited due to missing permissions

Bounty: 100

I am using the optional Windows 10 feature "Unified Write Filter" (uwfmgr.exe) to protect kiosk machines from unwanted changes.
Now in order to deploy custom updates, it includes a Servicing User under which changes to the protected volumes can be performed.

To execute these custom updates, the script at C:Windowssystem32UwfServicingMasterScript.cmd is supposed to be edited. (official Documentation)

Now I am unable to edit this file since it is owned by the "TrustedInstaller" user for which not even Administrators have permissions.

enter image description here

What am I missing here?
Am I supposed to change the owner of this file?

Get this bounty!!!
