Repair Windows Files Using System File Checker

The System File Checker will work in both Windows 2000 and Windows XP
You must have administrator access to use SFC.
*You need to have your copy of the Windows 2000 or XP CD handy because at some point the System File Checker will usually ask you to insert it in order to continue.

If you're using Windows XP you should first try System Restore.
Go to Repairing Windows Using System Restore for detailed instructions.


If the System Restore Point didn't work go to

Start
Run
Then type in sfc /scannow
make sure you leave one space between the sfc and the /
Or you can copy/paste the red words above.
(As soon as you type it in it should start to run. No need to hit enter.)



That will start the system file checker, it will search the system files for missing or corrupted files and replace them with cached approved copies of those files. You can watch the progress bar to gauge how long it is taking.



The cached copies are stored by the Windows File Protection utility. It caches every new Microsoft Windows approved file as it is installed on your computer in a hidden system folder called DLLCache. If SFC can't replace the missing/corrupted files with a clean cache, or it cannot find the DLLCache, it will tell you that you need to insert the Windows CD.

If you don't have a CD this article may be helpful.
Ask Leo: I don't have an installation CD for Windows XP - what if I need one?

The last step, if the System File Checker was successful, is to go to the Microsoft Update page and download the latest service pack. That's the only way to insure you have the latest approved files.



Running the SFC does take a while. It has to check every file in the system and replace the missing ones. Then you may have to insert the CD anyway. That's why I recommend going back to your last system restore point before trying the System File Checker. A restore point when you know that everything was intact.

*There are two other command prompts that you can use regarding system file checker.
These commands work in Windows 2000, but will not work in Windows XP.
sfc /cancel - this will cancel the scan.
sfc /quiet - this will tell the utility to run the scan and replace missing/corrupted files without prompting the user.

Repairing Windows XP using System Restore

    Or how to fix a bOrked Microsuck

    About System Restore:
    System Restore is available in Windows XP and Vista (which sucks btw, stay away from it at all costs. Seriously. I'm not kidding. It's a resource hog and it makes the average PC run slower than snail snot. And that's really slooooooow.)

    System Restore in Windows XP will automatically create a backup of the system files and settings whenever a new device, driver, update, or application is installed. That means that when you hit the 'install' button the first thing XP does it take a backup snapshot of the system--and then it begins the installation process.
    If there is a problem after you install a new device or application, or uninstall an old one, you can go back to a former Restore Point, a date when the system was stable, and that will usually fix the problem.

    The things that will not be changed by reverting back to a former restore point are: The files in My Documents, Internet favorites, email settings, pictures, music, etc. Basically, it is safe to use without fear of losing your data and personal information.

    System Restore is automatically activated as soon as you load XP, so, unless you have disabled it or changed the settings manually, it should be making a new restore point every day.

    To check and see if System Restore is enabled or to adjust how much space you have allotted for it (the more space, the more restores you have to choose from - 200 MB minimum)
    Right click My Computer. Go to Properties. Click the System Restore tab. There is no option to restore or create a retore point here. It will simply tell you whether it is enabled/disabled, let you change how much space it is allotted and it should say that it is 'monitoring'.



    **System Restore requires a minimum of 200 MB of free hard disc space or it will disable itself until the space is available. It will use this space until it's full and then, when it is full, it will re-write over the oldest data.
    To check the amount of free space on your hard drive Right Click on My Computer, Click on Properties. The General tab will show you how much disc space you have and how much of it is free, it will also display this information as a pie graph.




    **System Restore cannot recover personal files or email messages, etc. It will only effect system files and settings.

    Before you try System Restore:
    Try these troubleshooting tips.

    It is recommended that you try to re-boot the computer before you use system restore. Many times the system will correct itself after a new installation or uninstall just by re-starting.

    If you're having trouble restarting you should try booting in safe mode. Turn off the computer. Count to ten. Turn it back on. Hit the F8 button continuously as the computer starts but before Windows launches. Scroll to highlight Last Known Good Configuration and then hit enter.
    If Windows launches before you are in safe mode you'll have restart your computer and try again. It's a pain in the ass the first time you try. Most people don't make it into safe mode the first time. No need to be embarrassed. I failed my first 3 times. Now that's embarrassing.


    How to Use System Restore:
    Go to Start
    Programs
    Accessories
    System Tools
    System Restore



    The System Restore dialogue box will open.
    (This is the same box you will use if you ever want to manually create a restore point)
    Click on the 'Restore my computer to an earlier time' radio button.



    A dialogue box with a calendar will open. You can use the arrows to see the restore points for different months.
    Choose one of the dates that are in bold. (Bold means these are dates that have a restore point)
    Click 'next'


    You'll then be asked to Confirm Restoration Point Selection.
    Make sure that this is the date that you selected and then click next.

    Windows will then automatically shut down and restart the computer.
    When the computer restarts you will see a dialogue box that says Restoration Complete.
    Click 'Okay'.



    Test the computer to make sure that the problem was resolved.
    If the problem was not solved you should immediately undo the restore. (I mean it - right now! Undo the restore if it didn't work.)

    How to undo a System Restore:
    Follow the same steps as above but when you get to the System Restore dialogue box there will now be an option to 'Undo my last restoration'.
    Click that option then next.


    Click next in the Confirm Restoration Undo dialogue box.

    Windows will automatically shut down and restart again.
    When it restarts you will see a dialogue box that says Undo Complete.
    Click Okay.

    *If you aren't sure about the date that you started having problems you may want to try to restore from several points to see if you can find a good restore point.
    For example, if you recently uninstalled a program and now you're having problems you might want to use a restore point before the program was installed to see if that will solve the problem.
    Just remember to 'Undo Restoration' after each restoration that was not successful, and before you attempt another restoration point.

    **As I said previously, System Restore Cannot recover personal files or email messages.
    The best way to insure against this type of data loss is to do backups on a regular basis. Unfortunately you can't backup XP to a CD-RW using the backup utilty. I do have some other useful suggestions to get around that. I'll cover those soon ;)

    This post was written for SeaRabbit, because her machine has gone wonky and I don't want her to miss HNT. It's always something to look forward to ;) Sorry I was so late getting this up, I actually wrote it last week, but came down with Strep over the weekend so I have barely lifted my head out from under the covers for a few days.
