Gents, I dont normally join threads, yet I had to join and post in this one. I read all 26 pages. I was at a loss on getting SGX working on my new build. I am running an i7-7700k with Asus Z270-WS Motherboard. After getting the BOIS updated and the SGX only listed as "Software Controlled" in the BOIS, I could not SGX recognized using Intel's Tool. SGX PSW package wouldnt install. I then took @whirlpool's direction and partitioned my hard drive to UEFI. That got the PSW package to install. Then a new problem popped up. Intel Management Engine wouldnt work, along with SGX not being enabled. I soon got fed up and un-installed the Intel Management Engine. That wasnt smart as I couldnt get it to re-install. After doing some looking online, I decided to do an actual fresh, clean install of Windows 10. That did the trick. I took the PSW and copied it into system32. Ran Power Shell as admin. it installed with no problem. Installed POwerDvd 17, and the adviser. Ran the adviser, and got all green check marks. Popped in Sicario. Got an error the first time. Restarted PowerDvd and it played with no problem. I'm guessing that there were leftover conflicts in the system from me not doing a clean install and trying so many different methods. @triffid you can update your list and confirm that Asus z270-WS is good to go.
