Doors and Windows

Doors and Windows both today.  Four solid wood doors that didn't close properly or caught in the rugs when opened.  So, I took them off, hauled them outside and took the power planer to them.  Now they all fit , all close properly, and none get stuck on the rugs.  We are mainly Mac in this house, but we have to have a PC as well for some tasks, such as specialist software not available for Mac.  So, whilst working on the doors I thought I would work on Windows too, or rather, upgrade to Windows 10.  Seamless enough to do and looks a bit more intuitive than its predecessors, but miles away from Mac's Yosemite.  Oh yeah, that needs upgraded now to El Capitan, who thinks these names up?!!
