• (len($icode) <> 0)
  an empty entry may result in a registry key like:
  "HKLM\...\CurrentVersion\Internet Settings\\Cache\Content"
  which isn't a legal key.
• (Instr("123456789",Substr($icode,1,1)) <> 0)
  internet explorer is using different subkeys for different internet versions
  f.e. 5.0, 5.5, 6.0.
  To speed up and to prevent unexpected effects we only want to serach through
  subkeys starting with a number.
