Please read this post completely before begining the fix. If there's anything that you do not understand, kindly ask your questions before proceeding.
Please ensure that there aren't any opened browsers when you are carrying out the procedures below. Save the following instructions in Notepad as this

IT IS IMPORTANT THAT YOU DON'T MISS A STEP & PERFORM EVERYTHING IN THE RIGHT ORDER.

Then click on Start Update. The update will start and a progress bar will show the updates being installed.
I also recommend changing the "Update interval" to something more reasonable like 12 hours.
