    Thanks for your prompt response, Guys,
    Tried again this morning to run sfcscannow from both command and elevated commands but received "Cannot determine file system of drive C".
    I recently re-installed Win7; my thought was that I had corrupted system files, but that did not change squat.
    Hope this forum is more successful.
    Thanks again

    You might consider a repair install of the OS if you have a retail installation disk. You will not be able to use an OEM Windows 7 Factory Restore/Recoverytype of installation disk that came with or was created from a store bought computer to do a repair install with. These can only be used do a clean install instead. A repair install will not affect your user accounts, data, programs, system drivers, etc.

    Hi and thanks again for your prompt responses,
    Just got through trying safe mode; puter aborted twice after loading Drivers \Class PnP.SYS; tried running "startup Repair"; something strange hit me; in the Startup Repair Window.
    Windows Directory = F:\Windows; but I don't have an F partition on my HD: I have a 100MB Reserved, C 50GB(System), D 20Gb(Apps) and E 230GB(DATA). F & G are my optical drives.
    As above, recently did a repair install but no change in stated problem. Is there something I missed or should I format C and then reinstall? I have recently bought the family pack Win7 Home Premium DVD.
    Any ideas?

    Great Tut, Brink,
    Just one little thing will clean it up a bit for Noobs like me; in step two "Notes" #4 "If still not, then you can use the TIP in and with OPTION TWO below to manually replace the files that SFC could not fix." seems to point to Option two below, but the option below is #3.
    Should that be " use the TIP in OPTION TWO above"?
    Just asking
    Thanks for a helpful Tut, never the less.

    Hello Frank, and welcome to Seven Forums.

    Thank you. I updated the note. :)

    From your description, it may be best to start fresh with a clean install of Windows 7.

    Hello Locoelbario,

    The sfc /? command will only give you the details about the SFC command. If you wanted to run SFC, then you would need to use the sfc /scannow command instead.

    If I misunderstood what you meant, then please let me know. :)

    Hope this helps,
    Shawn

    Another strange one for you, Brink; or at least for me,
    After a repair install, ran sfc /scannow twice; crashes to BSOD at about 48% first time; rebooted and the second run went to 100%. Showed some corruption which could not be handled.
    Any thoughts?

    Hello Henfracar,

    You might run the sfc command a few more times to see if it may be able to fix them during this. If not, then do OPTION THREE in the tutorial to get your sfcdetails.txt file and upload it in a reply. I'll be happy to take a look at it to see what files it says it was unable to fix, and help with having you to manually replace them if needed. :)

    Thanks much, Brinks,
    Iran sfc 7 times; BSOD'd first time; next two stopped at 49%; next two at 67% next two went to 100%.
    As per your directions I generated the sfc details report - see attached file.
    Again, thanks a million, and God bless.
