I have a Windows Professional 7 machine that works fine, but I keep getting this "Windows Explorer is not responding" when I go the Start menu. I have to choose "Close the program" and wait a few seconds, then it's fine. What do I check to fix this? I tried using the Install DVD, but that isn't working, as it says I have the wrong DVD, but I know I am using the right one. Anyway, are there any hotfixes or things I can do? I have so many programs on this machine, really want to avoid reinstalling the OS.
I have also run Malwarebytes and Adwcleaner and the first time I ran them, there was some adware. I removed all the that, uninstalled Mwb and Adw and restarted and still does it.
I now have a hunch it might be a Flash update that keeps trying run. An "Update Adobe Flash Player" window just popped up and now I notice that Windows is not hanging. It had been hanging relentlessly all morning, as in, I would choose "Close the program" from the "Windows is not responding" window, Windows would start working again for a few seconds, then hang again. Anyway, now that the Flash popup is open, Windows has not hung, at all. I have purposely been putting off installing that, as sometimes a Flash update jacks some of our software. How can I verify this is what is causing Windows to hang?
