When it comes to computer security programs, you need to make sure that the ones you use always stay up to date and you download newer versions as soon as they are rolled out in order to guarantee maximum protection for your computer. This also holds true for Microsoft Security Essentials. Like most computer security programs, Microsoft Security Essentials comes with an in-house Upgrade option (found in the Help menu) which can be used to check for any new MSE updates and also download and install any that are available.
All you need to do in order to check for MSE updates and install any that are available is launch MSE, open the Help menu, click on the Upgrade option which will open the upgrade wizard, and click on the Upgrade button in the upgrade wizard. However, quite a few Microsoft Security Essentials users have reported being met with error code 0x80248014 when they do so. You see, MSE’s Upgrade option uses Windows Update to check for updates, and this issue is caused whenever Windows Update has any corrupted downloads in the directory where it stores its downloads.
To fix this issue, all you need to do is stop the Windows Update service, rename the folder where Windows Update stores downloads so that Windows Update is forced to create a new folder (one which does not have any corrupted downloads in it), and restart the Windows Update service. In order to do so, you need to:
- Press the Windows Logo key + R to open a Run
- Type cmd into the Run dialog and press Enter to launch an elevated Command Prompt.
- One by one, type the following commands into the elevated Command Prompt, pressing Enter after typing in each one and waiting for one command to be successfully executed before typing in the next one:
net stop WuAuServ
ren %SystemRoot%\SoftwareDistribution SoftwareDistribution.old
net start WuAuServ
- Close the elevated Command Prompt.
When done, simply launch Microsoft Security Essentials, try to check for and install any available updates and see whether or not the problem has been resolved.
