Comrades!
Good day.
There is a flash drive with Task Sequence.
But the installation from it fails.
It fails because it takes more time to initialize the Ethernet connection than to start the next action in the order, for example, downloading the office.
those. installation go-go, then reboot, go and fell.
How to replace some parameters on a flash drive with Configuration manager?
for example, in the registry, cancel the Backup Bitlocker recovery key in AD?
