Easy Fix: Microsoft Security Essentials won’t update: Error 0x80248014

0x80248014 Error

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 Fix

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
cd %windir%
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 theΒ 0x80248014 error occurred after cleaning the computer of a nasty virus.

  1. Worked perfectly on an x86 Win7 machine. Thanks!

  2. Worked perfectly on x86 XP machine. Many thanks!

  3. I am having the same trouble with Microsoft Security Essentials not updating? When I did the cmd trick I got access denied. Now what?

    1. Hi Steve, make sure you open an Administrative command prompt. In Vista/7 click on Start, type cmd, and instead of pressing enter, right click on ‘cmd’ at the top of the start menu and click “Run As Administrator.” I’ll update the blog post. Thanks for commenting!

    2. Hi. I’m having the same issue but when I click on ‘Run as Administrator’, the command prompt only flashes for a brief moment then disappears. It’s not giving me the chance to do the steps indicated. Please help. Thanks.

    3. What version of Windows are you running?

  4. I did all the steps that you have mentioned, but it has the same problem and same error!!! what should I do now?

    1. You might just need to uninstall it and use a different antivirus program like Avast. I’ve seen some machines that would require a reload to actually get MSE working again. Its rare, but it does happen.
