That’s interesting. As you show in your screenshot of RegEdit, “MS Shell Dlg 2” is just a pointer to an actual font file on your system (in your case it’s “Tahoma”), and as far as I’m aware, these “logical” fonts shouldn’t normally be exposed as a selectable font in any applications. I have checked on my system and although it appears in the “FontSubstitutes” list just like yours, it doesn’t appear in any of the fonts available in any of the applications I’ve tried (Affinity, Lightburn, MS Word 365, CorelDraw, Lazarus). I’m curious why this isn’t the case on your system.
There’s more information on these logical fonts here: Using MS Shell Dlg and MS Shell Dlg 2 - Win32 apps | Microsoft Learn
EDIT:
Ok, so I found another forum thread on this here: Can Not Find MS Shell Dlg 2
I also googled it and had this “AI” reply, which indicates that Older Lightburn versions might have enabled it to be selected.:
MS Shell Dlg2 isn’t an actual physical font. It’s a special logical font mapping in Windows used to tell the operating system which default UI font (usually Tahoma) to use for dialog boxes. It occasionally shows up in font dropdowns due to how certain applications scan the registry. [1, 2, 3, 4, 5]
Why You See It
- Logical Mapping: Windows uses this alias so older programs can dynamically pull the best system font.
- Application Behavior: Programs like Affinity, LightBurn, or other software that pulls directly from the Windows API will display this system pointer in their font lists. [1, 2, 3]
Is It a Problem?
- No: It is entirely normal behavior on Windows.
- Effect: If you select it, the application will simply render your text using Tahoma.
- Removal: You cannot “delete” or “uninstall” it, as it isn’t a true font file (like a
.ttfor.otf). It is hardcoded into the operating system registry. [1, 2, 3, 4]
What You Should Do
Because it serves as a system placeholder, do not use it for your own text design or document creation. It is best to ignore it in the dropdown and format your documents or designs using standard fonts like Tahoma or Segoe UI, ensuring they render correctly and consistently.
