Yes. I can say I have seen this phenomenon. - You go to highlight some files to be copied to another location, then go to that location and
click "Paste", and find you get that message. I can't say when it occurred, but within the last month or so. Of course, on checking, I found
the files were actually there. I couldn't
"figger rit out " at the time.
Today I was doing the same just before I logged on here again (like about <10min from this post) and this did not happen again.
Maybe it has been fixed
I have never seen the second issue - ads on screen - that you mentioned - that I can remember
Maybe I switched it off ages ago - like in the Win 8.x manifestation, but I don't know. Of the 3 machines I
have running on Win 10, I have not seen this one. Perhaps it is a proclivity of the brandware installed, for
example, some annoying alerts about installed apps pop up on a Toshiba we use in the house, but...
However, it's good to be apprised of these possibilities, so ta for that.
