How To Adjust Micorsoft Security Essentials Auto Update Interval From The Registry

Fix MSE security updates using the registry

Earlier this week we learned how to fix infrequent virus definition updates in Microsoft Security Essentials (MSE).  If you had trouble using Task Scheduler, or if you just prefer to tweak the windows registry, this tutorial is right up your alley.

Step 1

Click the Start Menu Orb and Type regedit into the search box.  Click it when it Pops

open regedit in windows 7

Step 2

In regedit, Browse to the following registry key:

HKEY_LOCAL_MACHINE/Software/Microsoft/Microsoft Antimalware/Signature Updates

find the correct registry key in windows 7 regedit

Step 3

Note that this registry key is protected by Windows, in order to modify you’ll need to grant your user permission, and we have a tutorial for that here.

Right-Click the DWORD named SignatureUpdateInterval and Select Modify.

The default value for the DWORD is 18, but to make the updates happen more frequently you can change it to a lower number, such as 4.

change the value data of signatureupdateinterval


Now MSE should update more frequently on your system, hopefully this will prevent you from missing important virus definition database updates.  Again, if you’d rather not edit protected keys in the registry please refer to our previous article on doing the same thing with Task Scheduler.
