I bet that laptop is forced to 32bit via SMM or whatever because IIRC
there was some issue with the graphics drivers for 64 bit windows when
they were hot of the press 10 years ago.

It's more than 'lake'. You'd need also a mindmap for trail, ville and
whatever magic endings they have. There is no mnemotechnic hint to map
them into something which makes sense.

I gave up long ago and the only thing I ask for is to provide me the
family/model number instead of the random code name of the day.
