Prior to the anniversery update, my bootup pic/wallpaper was from a
photo. After the AU, the bootup pic was either a scene of the seashore
viewed from a cave or a covered suspension bridge. Then after an
cumalative update, a head & shower figure was added with no "update
history" listed; then sometime later my original bootup pic which
was from win 7 & 8 took the place of the black figure & no trace of an
update as per the "update history".

Today, the bootup pic/wallpaper returned to what was used in
win 7 & 8; NO "update history" for the action.

Looks like windows 10 is messing around with the system when it is
running & looks like changes are made even if there is no update
or patch involved. Or is it some changes are not recorded?


Go to setting/personalization and set "Background" and "Lock screen" to
"picture" instead of "slideshow" then you will always have the same
picture showing.
