    System File Checker

    I read The kernel: Delving into Windows’ core by Susan Bradley
    http://windowssecrets.com/on-securit...-windows-core/
    and am interested in the section
    Techniques for keeping Windows’ kernel healthy
    Use the System File Checker (SFC.exe) tool to repair missing or corrupted system files
    http://support.microsoft.com/kb/929833#manually repair
    How to manually replace a corrupted system file with a known good copy of the file
    Note: You may be able to get a known good copy of the system file from another computer that is running the same version of Windows with your computer

    With the issues some of my friends have on how they use their computers, there are times I’d like to check their system using the System File Checker before their issues get worse
    However, the Microsoft link deals with manually replacing corrupted system files and I suppose that might be ok if there’s only 1, maybe 2 such files involved.
    --- Plus this approach is dependent upon finding another computer along with the description that this method may work

    I believe I have read, the best way to use the System File Checker is with the computers install disc.
    --- If this is true, that’s almost a futile approach: in my experience I’d say the chances of someone having their install disc is about 1% of the time
    --- My question is: am I correct in thinking that the best way to use the System File Checker is with the install disc?
    --- If this is the case, I’m not going to count on using the System File Checker as a “maintenance” tool although it appears to me I could use the report to point out the system files involved

    Another question is: will a System Repair Disc work to replace a corrupted system file?
    --- Whenever I help someone on their computer one of the first things I do is create a System Repair Disc if they don’t have one and then leave it with them with specific instructions to keep that disc in a safe place in case its ever needed

    My question is: am I correct in thinking that the best way to use the System File Checker is with the install disc?
    It depends upon the operating system. Windows XP does need it, and it's the worst system file checker of all, even with the disk. (DLL hell)
    With newer systems like W7 and greater, if you can boot to windows you can run the system file checker without the install disk.
    In order to perform a system file check on a non bootable computer you will need the install disk, not the repair disk.

    Replacement of a system file or DLL file may not be enough, it may require registration as well, especially in
    older OS's like XP and earlier. System File Checker in newer OS's will perform this if needed, so manual registration is rare.

    Another question is: will a System Repair Disc work to replace a corrupted system file?
    I'm hesitant to say yes, just due to the fact that the average OS created system repair disk is so limited.

    In order to run an effective System File Check from a bootable disk (from a non bootable computer) you will need the genuine OS DVD to boot from.

    Good one Zig, there have been times I have been too technical and sometimes not
    --- I guess this time I wasn't technical enough

    High Sierra I don't help the ones who don't want to bother even in addition to backing up.

    I've got plenty of friends and acquaintances like that, they just don't get it and probably never will.
    They just blame MS, then move to MAC where everything is controlled for them.
    After all is said and done, they're just to tired or embarrassed to complain about MAC when a problem occurs with it.

    C'mon Clint, everybody knows Mac hardware doesn't fail and it's pretty obvious Microsoft invented software bugs, so no one will ever issues with a Mac - unless you run Microsoft's Office for Mac, in which case the dreaded bugs will come back to haunt you .

    Well, I've been using an Ipad for over two years now without any security software and haven't had a single major issue. OS updates run without a problem. I'm actually pretty impressed with IOS. Of course, I haven't had a major issue with Windows or Windows Updates either. For me, both OS's have their place.
