I'm going to say that it is highly likely that we will see a new build tomorrow. 10074 has been in the External ring for a while now and usually, it doesn't take that long before a build gets released to Insiders if it is in that ring already. If they do say "in the coming days", it's just for the sake of waiting.
Just upgraded to this build, and for me, it's a complete dud. The upgrade process went smoothly, but the laptop now hangs at the lock screen upon power on. It then blue screens with this error message at the bottom: "DPC_WATCHDOG_VIOLATION" I am now trying to figure out what to do. Where can I download an ISO of this build and start from scratch? Also, the graphical environment for various recovery related tasks never comes up. Is Microsoft serious about not allowing "F8" to invoke safe mode? How stupid is this billion dollar company? The recovery screen never comes up. How do you get around this crap? MS can't rely on betting on this environment always popping up when a problem happens. There needs to be an F key to invoke to override their stupid architecture!
At this point i doubt that will be 10074, maybe it will be 101xx with all new changes to cortana and other.
I've heard that in Windows 8, turning off Fast Startup solves that problem, I mean, DPC_WATCHDOG_VIOLATION.
How do I turn off Fast Startup when I can't even get into the OS? The Recovery screen never even comes up. There needs to be an F key option, and brilliant brains at MS didn't provide this. Purely idiotic. This is why I run Linux.
How am I supposed to get into safe mode when MS eliminated the F8 option and the recovery GUI never comes up?
In my case it turned out to be the Synaptics SMBus Touchpad driver. A clean install will not help you; I tried that and it has the same problem. You need to get an external mouse and use it to change to a different Mouse driver in the Device Manager. (I am using PS/2 Compatible) Do not touch your Touchpad even when Windows is starting. Doing so will cause the violation. Hopefully Microsoft will pull the Synaptics update soon. Stopping it from installing Automatically can be a real PITA, but it can be done.
It's already been 5 times. People need safe mode when something fails, not relying on some automatic system to dump them into safe mode (which doesn't work and may always fail in certain circumstances) no matter how well coded. There's a process to enable F8 in Windows 10, but it's too late in my case. Now I'm hosed. It's fine because it's just a test laptop, but this just proves MS's poor architecture.
