Neither registry uninstall info or file info (%ProgramW6432%\pinga\pinga.exe) display full version info, so one can't easily figure out whether the version installed is the latest one (ex. v0.42g).

Please write full version info to Windows registry when installing pinga. Please also use standard version numbers, with numbers instead of letters for the minor updates. "0.42.7", instead of "0.42g".

Now that winget supports installers inside ZIP, writing full and proper version info to the registry would allow pinga to be installable and upgradeable by winget.
