SVN showing Windows Firewall icon instead of Green Tick

Question

Suddenly a fully up to date repo looks like this:

A separate repo looks like this (folder names redacted) - as you can see, out of date files still have the correct icon (red !):

Inside a folder, any up to date files look the same:

I've tried SVN Cleanup -> Refresh shell overlays, but this had no effect:

What is causing this and how can I get my lovely green check mark back?

Answer 1

Try letting Windows rebuild the icon cache.

1. Press Ctrl+Shift+Esc to open the Task Manager.
2. Kill explorer.exe¹ (your taskbar will disappear).
3. Click menu File → New task
4. Type cmd Enter to open the command prompt.

5. Type (or copy-and-paste):

   del "%localappdata%\IconCache.db" /A
   

   Enter

6. Go to the Task Manager and click menu File → New task.
7. Type explorer.exe Enter to regain your task bar.
8. Restart your PC to let it rebuild your icon cache².

¹) Explorer might hold the icon cache file hostage in which case you can't delete it. That's why the explorer.exe process must be killed.

²) A reboot is not required for everyone.
