I have figured out to how to get windows defender to work with the error code in affect! Go to start menu, search, run, regedit.exe, hkey_local_machine\software\policies\microsoft\windows defender. Look to your right in the same window and you will see DisableAntiSpy... right click on that then left click modify make the value data zero. min the window go to control panel click windows defender it will ask to turn back on, then click it to. it will say the same error code then close the error code window and there is your windows defender!!!! You will have to leave the value data at zero though!! If that works close the regedit.exe window. Hope you didnt delete anything yet when you make the value zero thats just what it registers as!!
