I received the 0x00000024 error yesterday after an automatic Windows update (XP). I was finally able to boot after running the "chkdsk" command, but now many programs are no longer working. My PC is fairly old, so my first thought was to do another backup of my files. It's crazy because, for instance on my desktop I can open file folders, but I cannot drag, move or copy them. Internet Explorer won't open and I'm not able to restore. Has anyone had this type of issue before? Thanks for your help.
