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:
Hsilgos/nppsaveasadmin#24 (comment)

Also, UAC is supported starting from Windows Vista.:

Starting from version 7.9.3, Notepad++ isn't supported on the Windows XP.
This makes it possible to implement UAC properly.
