I have a Windows 8 Laptop. OEM Install. Used it for one month with no issues. During that time the system was not joined to the domain. No issues to speak of at the time. Monday I went ahead and added it to my corporate domain. Now, UAC is turning itself off on reboot. Metro apps do not run, then I enable UAC, which requires a reboot to take effect. Upon the boot, all is well. On the next boot UAC is off again. The cycle repeats.
I'm suspecting something int the Win 2008 domain policy is causing it, but I cannot find the issue.
