Win32::Exe has issues for a long time Bug #110605 for Win32-Exe: exe_update produces broken EXE file when ProductName/FileDescription is specified

But

To change pp icon uninstall PAR::Packer, replace .ico file, reinstall PAR::Packer

citrusperl/cavapackager support making exe with .ico file changing, and without using Win32::Exe (IIRC)

See createdistribution/createexecutable or cavapackager

To hide children use  use Win32 qw(SW_HIDE); Win32::SetChildShowWindow(SW_HIDE); Wperl.exe fails with Tk + piped process ( Win32 )
