New Computer

Bought a new PC yesterday, as my old desktop was displaying multiple blue screens of death.  The process of setting it up and moving from the old one is familiar, yet a bit different.  In the old days you'd be told about moving files from old to new, because everyone upgraded their PC to the newest and greatest version.  No such instructions these days, perhaps because they know the likely reason for a new purchase is the old PC is dead?  Or perhaps they figure the newbies are not buying desktops, but tablets or laptops or whatever, and the old timers who are stuck in a rut with desktops can figure out what to do.
