I use Win10 on my work laptop (was going to go Mac the last update until I discovered that it won't do OLE embedded pdfs in Office files, which is a must have for me.
I normally sign out each night instead of shutting down. Once a week, at least, I find that the Explorer doesn't refresh itself, as in
create a new folder
it doesn't show up
nav back, the back to where you were. Now it shows up as "new folder"
Rename it. Still shows as "new folder"
nav back...
Now it appears with the correct name.
Irritating, and something I never have on a Mac. Restart and move on. PITA.
