Thanks for your help CentBrowser.
I deleted the icon cache file, shutdown, rebooted and the icons were messed up.
I restored the icons.
I then did the Reset Folder Options, shutdown, rebooted and the icons were messed up.
It's been fine for weeks now and suddenly it starts again.
The only things I can think of that have changed are:
Monthly Windows updated.
CCleaner updated.
Avast updated.
Firefox updated.
Cent updated.
Other hidden/auto updates.
