I tried to install the new Extended Kernel from November on my Haswell PC with the April 2017 update, using the .bat file, after rebooting, it gives me a fast BSOD (telling me USER32.dll was not found, c0000135) just before the logo animation happens.
Did I do anything wrong?
Forgot to mention that before rebooting the OS literally breaks, and I'm not able to even run apps with admin privileges since they give me a Filesystem error.
