Hi,
I've noticed an issue after installing ipinfo with winget and decied to share my thoughts (solution) here.
At this point of time the installation path is: "C:\Users\YourUserName\AppData\Local\Microsoft\WinGet\Packages\ipinfo.ipinfo_Microsoft.Winget.Source_8wekyb3d8bbwe" (this location is added to PATH, so no worries for that)
Executable name is: "ipinfo_3.3.1_windows_amd64.exe"
Solution: Rename that file to "ipinfo.exe" and restart your terminal/PowerShell
