Changing icon bug

I changed the icon to a temp one in my build settings for standalone windows.
It worked at the time, but when I went to change it to something I actually wanted to use, the .exe file kept the temp icon.

Even though the running window had the new icon at the top, the .exe remains with the old icon no matter how many times I change the icon or rebuild.

How do I fix this?

Never mind, I restarted my computer and it fixed itself.

Weird bug though.

I think it’s Windows Explorer caching the Icon. Especially if you put it on the Desktop. I’ve seen that bug with other type of software (non Unity related). Once I renamed the file - the icon magically changes. Renamed back - the old icon was back. Must be a caching issue.
