Yeah, but I would love to know the differences between each version lol. Despite all my knowledge about Laptops, still can't know the difference between them.
@DragonMals Until a few years ago I've been using PCs with 16 bit 8088 and 80286 CPUs. Sadly the HDDs died at some point (Seagate ST-225 for example if you need a search term). I still hope to repair these systems one day. PSU are kaput, capacitors failed... I'm really sad this pieces of history failed because of the ravages of time.
@Xdqwerty 32 bit CPUs aren't necessarily limited to a 32 bit address bus. PAE existed before and to my knowledge Windows 2000 Server (Datacenter) supported more than 4GB RAM. Not that anybody way able to pay such hardware back then.
For whatever reason Microsoft disabled PAE feature in consumer editions of 32 bit Windows
