Windows 10: Access Denied unexpectedly

This is more of a Windows issue than a C++, yet I'll mention C++ briefly.

I get ACCESS DENIED when I try to open certain files for writing in a C++ program.

DETAILS

Observation A

1 I use File Explorer to create the text file "CreatedByFE.txt".

2 My program written in C++ attempts to open "CreatedByFE.txt" for writing.
I get ACCESS DENIED.

[C++ note: this occurs whether I use std:fstream, FILE*, or CreateFile.]

Observation B

1 I use MyProgram.exe to open a new file, "CreatedByMe.txt", for writing.
This causes a zero-length file to be created.

1a I exit and restart MyProgram.exe just to make each step 2 similar.

2 My program written in C++ attempts to open "CreatedByMe.txt" for writing.
It succeeds.

["CreatedByFE.txt" and "CreatedByMe.txt" reside in the same directory.]

Summary:

If I create a text file using File Explorer, subsequent attempts by my program to open it for write result in ACCESS DENIED.

If I create a text file using my program, subsequent attempts by my program to open it for write succeed.

Observation 3

If I examine the properties of the two above text files "CreatedByFE.txt" and "CreatedByMe.txt", I find that they are identical: attributes, permissions, and ownership.

Observation 4

Although MyProgram.exe cannot open "CreatedByFE.txt" for writing, I can edit "CreatedByFE.txt" with a text editor. Clearly, the text editor can open it for writing.

Observation 5

I noted that MyProgram.exe was owned by myself the user, say "Me", and that TextEditor.exe was owned by "Administrators".

I changed ownership of MyProgram.exe from "Me" to "Administrators".

MyProgram.exe still got ACCESS DENIED when attempting to open "CreatedByFE.txt" for write.

Observation 6

MyProgram.exe gets ACCESS DENIED when opening "CreatedByFE.txt" for write, even if run as administrator.


QUESTIONS

1

`Why is it that my program can open "CreatedByMe.txt", but not "CreatedByFE.txt", when they have the same properties, and reside in the same directory?

SOMETHING about them must be different.

It's not the filename that's the issue.
I transposed filenames using a "temp" filename to perform the swap.

I'm unable to open the file created by File Explorer, regardless of filename I just wanted to confirm that it wasn't some odd issue related to a filename in the registry.

2

Why can a text editor open a file or writing, that my program cannot, when the the editor and my program have the same owner?

BOTTOM LINE

The text files have identical properties and location.
The exe files editor and my program have the same owner.

How do the two text files differ?
[So that I can open one, but not the other.]

What is the difference between the text editor and my program, allowing the former to open files that mine cannot?

What the heck is going on?

I really dislike Windows security.

Thanks.

After following the steps suggested, I get the message "Access denied" in command prompt.

Please advise how to allow permission.

net user administrator /active:no keeps saying access denied.

Hi Rebekah,

It's possible that you're not using an elevated command prompt, causing the Access Denied error. We suggest following these steps to properly disable the built-in administrator account:

• Right-click the Start button.
• Choose Command Prompt (Admin).
• Copy and paste net user Administrator /active:no and press
  Enter. If the command isn't successful, please post a screenshot so that we can study it further.

Let us know if you're able to hide the administrator account after following these steps.
