Hello, This is my second attempt at using Windows 10. I couldn't get EMET working properly on the first try, but I decided to give it a final shot before going back to Arch Linux. So, my main problem: I can't enable DEP system-wide. EMET says that the BitLocker service must be suspended, I click "OK", then it just says "Error". Since I can't post links yet: https : // imgur . com / a / 5dplw (Sorry to do it this way, I need help, and the link is not malicious.) Does anyone have an idea why this happens? The not-so-important problem I installed Avira Free with the intention to use it as my main scanner (HIPS, Sandbox, and Firewall will be handled by COMODO). However, it disabled Windows Defender and it complained to me. Could there be any problems about it? Microsoft says that they'll turn on WD if it's off for a while, so will Avira just keep it disabled? Regards, Amarildo EDIT: I tried opening EMET_Conf.exe with the option "--system --force dep=ApplicationOptOut", but it just doesn't respond, it does nothing. I also edited the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\EMET\EnableUnsafeSettings registry KEY, with no avail.
