Windows Vista. Update Error Code 80072EFE

I'm so fed up with Vista, constant update error code and cant update since April 2010, windows defender won't update either, installed a service pack manually, but I cannot get security updates, keep getting error code 80072EFE, very frustrated at this point, scanned everything and it is showing no malaware, or virus, or anything, then it wont let me access my desktop unless I scan c disk for errors first (2 or more hours for scan) Oh just so many issues, I might try windows 7 . At my wits end with Vista premium 32bit......Thank you if you can help.......frustrated!!!


I have seen this error quite often.

Error 80072EFE is related to Update server closing the connection.

Mosty likely, the computer may be infected with ROOTKITS.

Try to run TDSSKILLER to find any rootkits.

Download and run from here

Then try to update Security Essentials
