I am having a problem with my explorer.exe process using up 100% of the CPU power for roughly 10-15 minutes. The common theme is this seems to happen whenever I start up my Sun VirtualBox virtual machine (running XP PRO SP3, 1.5GB RAM allocated) and open up the My Videos folder. I have a lot of custom video files in different formats (avi, mpeg, mpg, etc) and anytime I open up that folder the explorer.exe process climbs and stays at 100% for about 10-15 minutes before it eventually will free up the memory and go back down to a normal value.
I have researched on the net and tried some registry changes to no avail. The host machine that the virtual machine is running on is a 2 month old machine (HP Pavilion Elite 3.0GHz quad core 8GB RAM machine). It is very annoying and difficult to work when the explorer.exe process hangs. It ties down my machine and makes things very slow within the virtual environment. How can I fix this issue? Ideally, I would like to be able to open up the folder and not have the CPU power reach 100% and hang. I do not really have many apps running on that machine other than CCleaner, Spybot, Nero, and SAV Corporate. Any help is greatly appreciated.
