The question that you may have is “How can a user inadvertently and unknowingly add a file called “Program” (or some variant) to a system drive that ends up preventing a service from starting?”
One answer is through the incorrect use of the Change Directory (CD) command in a Command Prompt window-- that is a possible cause. For example, typing in a Command Prompt change directory command
in this manner “C:>cd C:>Program Files (x86)\ will add a file called “Program” to the system drive. The typo in the command has an invalid “>” symbol before “Program Files”, it will create a “Program” file on the system drive. The Command Prompt
window response to the invalid command is “The system cannot find the path specified” (In other words, the Command Prompt window does not let you know that you just created a file called “Program”).
Not saying that was the exact cause for this occurrence, but the above scenario WILL cause the “Program” file to appear on the C: drive.
