Save dialog should correctly elevate privileges (UAC)

[mere-human]

Description of the Issue

I would like to be prompted with UAC dialog when saving a new file or saving a modified existing file in a protected location that requires administrator rights.

Steps to Reproduce the Issue

I. New file:

1. Create a new file
2. File > Save as...
3. Navigate to any directory that requires administrator rights to write (e.g. C:\)
4. Press Save button

II. Modified file:

1. File > Open
2. Select a file that is located in a directory that requires administrator rights to write
3. Modify a file (add some text)
4. File > Save

Expected Behavior

UAC dialog appears asking for permission to save:

Actual Behavior

I. New file:

It suggest you to save in the documents folder without an option to save as administrator.

II. Modified file:

It tries to launch a program as administrator.
A side effect of that is all new modifications are lost.

Details

There is a plugin that solves this problem NppSaveAsAdmin
However, in version 7.9.3 it stopped working.
In the discussion, it was suggested to incorporate such a functionality into the Notepad++ itself:

Also, UAC is supported starting from Windows Vista.:
https://en.wikipedia.org/wiki/User_Account_Control
Starting from version 7.9.3, Notepad++ isn't supported on the Windows XP.
This makes it possible to implement UAC properly.

I'd also like to work on this one.

I'd also like to work on this one.

Please don't hesitate to ask me questions if you are going to use Save As Admin plugin as a template.
