I took my Acer E1-572 into the Acer agents to have my HHD password reset (I had a major problem). They deleted the password and reinstalled Windows 8. However they seem to have installed 8.1 instead of 8. I now have the message SecureBoot isn't configured correctly and Windows Update refuses to install 4 updates including KB2919355
I have run Windows Tweaking Tool and SFC.exe but this hasn't fixed the problem.
Can you suggest anything else?
