    Having done a bit of uninstalling and installing lately, I ran SFC and it found many altered files. Most were obvious upgrades so I just clicked on the updated file bit.

    Some, however, were rather odd and I just clicked 'ignore' until I could post here.

    To what does the 'date' refer? I found sometimes that the previous version of a file was of a later date than the current version. Sometimes the version number was the same but the dates were different. Sometimes an earlier date had a later version number than the current file.

    So what should I go by for the latest version : the latest file version number or the latest date?

    If the version numbers are the same, do I go by the latest date?

    Thanks.

    I would go by the version number. You can also get a clue as to whether the files are equivalent by checking their size. I've found these discrepancies (with respect to dates) between OEM installed files and ones on MS disks. But if the version and file sizes are the same, they are interchangeable.

    You can check the DLL data base to see if the version you have is correct for the installed products on your system:

    As a FYI, if you are in the habit of running SFC, a good practice is to run it before an install and ensure everything is fine. Then do the install, and run SFC again.
    In this manner, you can see the files affected by the install.

    Thanks, WhitPhil, that's an excellent tip - will remember to do that in future.
