I'm running Windows XP Pro. My windows directory has been growing to enormous proportions. One folder in particular (Installer) seems to contain most of the excessive files (67GB). Most are of the file types .msp and .msi. and seem to all be related to MS Office 2003! I believe most to be unnecessary duplicate files (even though the file names are different) because dozens and dozens of the files are the exact same size. I will say that, for a long time now, my security updates for Office2003 have failed to update. Does anyone have any experience with this? Why would this happen?
