F8 debug window no longer prevents reboot / restart in Windows 10 full OS, after upgrading to 1606 from R2 SP1
The problem is that after upgrading from R2 SP1 to 1606, customer found that the debug shell window no longer suppresses the TS from restarting the computer in full OS.
Updating status to completed as this is expected.
We actually never guaranteed that the F8 command-prompt will prevent the rebooting of a machine. It was just a side-effect of the implementation.
In older builds, we launch the command-prompt as part of setup-complete. This prevents the reboot while our setup-complete is still running. The problem is that with Windows 10, that will not work because the access to the desktop has changed.
Now, we launch the command-prompt from the TS Progress UI. Reboots now proceed without waiting for the command-prompt because our setup-complete is not waiting for the command-prompt.
