    I don’t see people complaining about forced updates now. Maybe they finally realized that it’s for their own good?

      Vera, you can download the direct installer from the Microsoft link provided.

      Before doing so i suggest that in the search bar that you type in winver and check that you do have the latest iteration of Windows 10 as some people are reporting that their computer has not been updated but, in actual fact, it has – apparently it is a bug for this particular version.

      Here’s the link and all the best. Make sure you select the correct operating bit – either 64 or 32 bit.
