Adept I

Icons have black square on them as I mouse over

I have an odd problem.

Desktop can look 100% fine, then as I move the mouse cursor over the icons, as I move the mouse over each one, they have a black square around them. It seems completely random when it does it.

Today it did it while installing a piece of software, then it had finished installing, the icons went back to normal.

Then a little later it happened again, no software being installed.

Very occasionally after this, the whole background pic turns to black.

Logging out and back in fixes it.

Paid for version of Malewarebytes gives a clean bill of health as does free Avast.

It's been doing this for a few weeks on and off. Yesterday evening I reformatted and reloaded Win 10. (well I reloaded from a trueimage disk image backup taken in May this year, then did win updates etc. has only been doing this for a couple of weeks or so)

Today it's still doing it. I just took a snip of part of the desktop after I moused over the icons,

edit: I just removed a USB drive and this is the result

I'll log out and back in and it will be fine, sometimes when I just do thinks like browse web, open software etc it sorts it's self out

Any ideas?

Many thanks

EDIT: Now the reverse is happening, I mouse over and the background reappears (haven't moused over them all)

This website offers tips on how to fix the issue your are having with the Desktop Icons: FIX: Black Squares Behind Folder Icons in Windows 10 -

From TenForums: ( this shows how to rebuild your Icon Cache in Windows 10)

This is old but should apply to Windows 10 and is basically saying the same tips in the above links. This is the exact problem you are having which is why I posted it: Desktop Glitch? Black Squares Whenever I Drag or Mouse Over Icons - [Solved] - Windows 10

This seems to be the same fix and procedure for Windows 7 as it is for the link from Tenforums concerning Windows 10: Thumbnail Cache - Clear and Reset - Windows 7 Help Forums
