I am having an issue that I am trying to narrow down. It started recently on both my desktop and laptop and the only think I can think of that changed was added KIS to my system. Sometimes when I open Windows Explorer it hangs and draws a windows frame with no menus or contents, just a white background. I saw today running Process Explorer that when you launch an explorer window it opens as a child process of svchost.exe. On my work desktop (no KIS installed) this opens 1 copy of explorer.exe and after closing the window the process closes within about 30 seconds. On my personal laptop the process hangs until a reboot. If I open another window it creates another instance of explorer.exe that gets orphaned as well. This happens until it hits 5, then I get the problem with the hanging window and I have to reboot. Can someone else running KIS 2012 duplicate? -Edit I may have found something... When you have selected "Launch folder windows in a separate process" in the Windows Explorer options it does this. If you uncheck that then this does not happen. Instead of launching another explorer.exe it launches a dllhost.exe that disappears within a few seconds. I don't know if it's a big deal or not. I can keep this setting if needed, but I recall seeing something about this a few years back and would not have suspected that the 2012 version would still be doing it. They should have their installer disable it if it is going to be a problem.
