Okay, I'm currently running Windows XP Home Edition with Service Pack 3 installed as a guest OS for a while under VMware Player and so far, I'm starting to experience some side effects to updating Windows XP. For some reason, while I'm using the 32-bit Microsoft Windows File Manager (found under \WINDOWS\System32\winfile.exe and originally taken from a Windows NT 4.0 SP6a installation), the CPU utilitisation spikes up between at least 85% to 100% and stays there until I terminate the process. Closing File Manager has no effect and the process remains there until I use either Process Explorer or the Windows Task Manager to close the misbehaving winfile.exe process. I believe that one of the security updates from June 2012 had a affect on this. I have provided a screenshot of what the problem looks like: How can I fix the problem regarding the excessive CPU usage running Windows File Manager?
