After i turned off everythng in my MSCONFIG to (optimise performance), i restarted my PC and is now unable to log into my windows user account. I get a windows security error msg, saying that the server is not responding properly and that i should verify that credential manager server is properly installed on the target. This error msg shows after i entered my password.I know now that their is some applications that i should not have ticked off when i was working in the MSCONFIG. Is there anyway that i can fix this problem to log in?
