Ever since upgrading to Windows 8.1 (with and without Update 1) from Windows 8, the File Explorer has new quirk in its behavior that drives me crazy. My computer is on a domain and has a mixture of DFS drives and the older network drives mounted to drive letters. Whenever I leave File Explorer showing either a DFS or network drive, after a few minutes of inactivity, it will close. I then have to reopen it and find the folder again. If I switch away from the File Explorer to go to something else, many times when I go to switch back to File Explorer only to find it has closed. This is really annoying. No error message, it just closes. The computers with Windows 7 and older don't do this. And Windows 8 did not do this. Both my desktop computer and my Surface Pro, both 8.1 Update 1 do this. My servers are Windows 2008 R2.
Is there any reason for this? Or is there any registry hack or setting that controls this behavior?
Thanks, Carl
