FIX: KB3212646 Update Causing Issues with Audio

If you are using Windows 7 and you recently installed the Windows Update KB3212646 then you may face issues with system event service being missing or broken.

The problem stems from the optional update named INTEL 10.1.1.38. This INTEL update doesn’t appear to be fully functional or is incompatible at this point. The solution would be to uninstall and hide the update so it isn’t reinstalled by itself. And when Microsoft releases a patch or an update to it, then re-install it.

Restoring and deselecting INTEL update

The Windows System Restore mechanism helps you to take your Windows back to some point (ideally to a point where your Windows was working fine). You can create System restores manually but Windows periodically creates system restore points for you as well. So if you mistakenly installed something, that you don’t like, you can use Windows System Restore to go back to a time when you didn’t install that certain software.

So, if you installed the INTEL update along with the KB3212646 update then restoring to an earlier point will undo the system update. Follow these steps to restore your system

1. Hold the Windows Key and Press R
2. Type rstrui.exe and Click OK
3. Click Next and choose Show More Restore Points
4. Choose a Restore Point before the update was installed and when the system was functioning normally.
5. Click Next, and Finish.

Now your computer will restart and take some time to restore. Wait for it to finish. If, for some reason, you can’t see any Restore Point in the above mentioned steps then follow these steps to uninstall the Windows Update manually.

1. Click Start then select Control Panel
2. Click Uninstall a program
3. Click View Installed Updates
4. Now locate and select the INTEL You should be able to see the exact time when the updates were installed. The most recently installed updates are on the top.
5. Once located, right click and select Uninstall

Now download Windows update again by following these steps

1. Click Start then select Control Panel
2. Click System and Security
3. Click Windows Update
4. Click Check for Updates
5. Now you should be able to see the updates selected. Click the link that says optional updates are available, right Click the INTEL update and choose Hide Update.

Now update your system and the Windows Update shouldn’t create any problems for you.
