If the computer is running automatic updates from Windows, shut that feature off. Microsoft has had a habit of late of "improving" the operating system and changing settings and even programs that you were using to suit what they believe the world should be. Shutting off the automatic update will stop a lot of problems in the future.

The man who sets out to carry a cat by its tail learns something that will always be useful and which never will grow dim or doubtful. - Mark Twain
