Description of the Issue

My Notepad++ theme keeps getting reset upon opening NPP+ up. I noticed this first happened when attempting to save a file that had write protection, and it asked me to restart it in Administrator mode. Following this, I clicked 'Yes' and restareted in Admin mode... following that, I lost my theme and it reverted to the normal light mode.

Afterwards, I set NPP to Dark Mode in the settings, saved and quit. Afterwards, I started NPP again to edit a file, and it was once again in light mode. My themes are gone, and every time I restart NPP dark mode is gone, too.

Steps To Reproduce

1. Have a custom theme on your Notepad++
2. Try to edit a protected file
3. Restart Notepad++ in Administrator mode when prompted
4. You should your custom themed colors/layout.
5. Set NPP into Dark Mode.
6. Close Notepad++ and open it again
7. Dark Mode is no longer enabled

Current Behavior

Notepad++ is losing my theme settings when closing and restarting it.

Expected Behavior

Notepad++ retains my themed colors and layout as well as Dark Mode preferences.

Anything else?

This issue seems to have begun with the latest update to Notepad++ which is as of writing this bug report, is v.8.6.5 (64-bit)

Start by reproducing the reported sequence in Notepad++ v8.6.5 on Windows: edit a protected file, restart in Administrator mode, enable Dark Mode, close, and reopen. Trace where theme and Dark Mode preferences are saved and loaded; done means custom colors, layout, and Dark Mode persist after restart.
