    MS UAC File Virtualization/Operational

    I was browsing through my event viewer today and I came across this event. I've looked around for an answer, and while I did find some information, it really only confused me more. If anyone can tell me what this is (I'm just a newb) I would really appreciate it. Also, I'm confused by the reference to "HarddiskVolume2". I only have one SSD in this machine, and the only partitions are the OS and the "restore" created by MS during the installation.
