Microsoft Security Essentials error 0x80248014 got you down? We’ve been there! We found an easy fix that should work great for you. Follow below for the simple fix.
I recently had a customer who got one of those “your hard drive is about to die” viruses. I removed the virus, fixed windows update that had been mangled, and thought he was ready to go. He called back though, and Microsoft Security Essentials would not update. It gave the error code 0x80248014. After doing some Google searches I came across a post on the Microsoft Answers website. Once I took these 4 steps it worked perfectly without even as much as a reboot.
The 0x80248014 can be caused by the Windows Update cache needing a cleaning. This is very easy to do, and the results are usually instant. Open an Administrative command prompt by clicking Start, then type “cmd”. Right click on “Command Prompt” and click “Run As Administrator”. We’re going to turn off windows update service, clear the queue and restart it. You can copy and paste in the following commands:
net stop wuauserv
ren SoftwareDistribution SDold
net start wuauserv
Now try to update Microsoft Security Essentials. It should immediately update without the 0x80248014 error. If it does not work, then you might try uninstalling Microsoft Security Essentials, running the fix again, and reinstalling it. If that still does not work, then it’s possible that the system has other errors causing Microsoft Security Essentials to fail. In that case, we recommend AVG Ultimate. You can get AVG Free, but it’ll nag you to buy it so you may as well just purchase a copy and be protected fully. Otherwise, you might consider reinstalling Windows, especially if the 0x80248014 error occurred after cleaning the computer of a nasty virus.
