How To Repair Windows 7 System Files
Posted February 8, 2010 – 6:01 pm in: Windows 7 GuidesThere are many reasons behind a corrupted system file. If you are getting an error something like “file missing or corrupted” message in Windows, you should try to repair one or more system files first.
But before you try third-party tools to repair system files in Windows 7, you must try a effective command line tool to repair corrupted system files.
In this guide, we will show you how to repair Windows 7 system files without using any third-party tools.
1. Type command prompt in Start menu search box and then hit Ctrl + Shift + Enter to launch the Command Prompt with administrator rights. Alternatively, go to Start, All Programs, Accessories, right-click on Command Prompt and then select Run as administrator option.
2. Click Yes if you are prompted with UAC (User Account Control) box.
3. Once the Command Prompt opened, type sfc /scannow and hit enter. This command scans integrity of protected system files and then repairs if problems found.
4. The process may take a few minutes. Once done you are good to close the Command Prompt.
You can also type just sfc in the Command Prompt to know more about sfc commands.

No need to type “command prompt” – you can simply type “cmd”
Ok, so you were going to show us how to fix issues with W7 using win os tools, got as far as SFC (great tool, isn’t it?) then what?…What are some problem mssgs that could show up in that screen? What would be the next steps?
You won’t see any other prompts during the repairing process. So you just need to follow steps in the above guide.
can u send more info about windows 7
Wrong. You can get errors using sfc /scannow and not showing those errors, nor describing what to do if such an error occurs is unhelpful for those people who experience those errors.
why dont you people stfu and just appreciate whatever the hell you are given
i did not even know about this sfc thing in the first place, so i learnt something from it
instead of bringing him down why dont you offer to help him improve the post azzwholes
aslam u alikum

Excuse me, would you please help me, i want to try way to repair windows 7 system files above, but how if cmd.exe also damage or even lost
please give me the solution
Try to restore your Windows 7 to a previously created restore point. This should fix the issue.
Hi I am trying to run sfc /scannow in win7 cmd but it says i need to be administrator to do this. Even though I am signed in as admin account. How can I get around this please? Thank you ever so much in advance
create a cmd.exe shortcut, then run it as administrator
I have a problem with my windows update, i ran SFC /scannow and i got a messege that some files are corrupt and could not be repaired. What do i do to repair these corrupt files?
To Paul, if you haven’t figured this out already (I didn’t see an answer), just go to All Programs|Accessories then right click on Command Prompt. Select “Run as Administrator”. Saves creating a shortcut on the desktop (that works, too…just more steps that you don’t really need).
when Im installing prince of persia the tow thorns windows is showing some fils are missing how to restor
so another option to fix a non booting windows is this:
put in your os cd, then go to the advanced recovery options
select command promt
type bootrec.exe
this will tell you the options
select appropriate option and reboot
Not helpful at all – this guide was definitely only half done, doesn’t explain how to do anything.
This article should be removed!!! For your own good, READ THIS FIRST:

Maybe mine was a little problem to some but I like to hear tunes when I’m using my Gateway laptop. It’s been 2 weeks ago I tried this and haven’t had a single issue with my computer. Thanks Again.

Hi,
I have a problem right now, I’m using windows 7 home premium edition, and one day I try to update my windows and suddenly my OS get crash and the result is I can’t login nor enter the desktop.
At the welcome screen, it said that “failure configuring service pack Reverting Changes”. Please, I need some help urgently. Thanks for your advice.
Thank you, but i want install new for Windows 7 but not change file systems ???
thank u very much ………u solve my problem ………….working for me
What a dumbass. How can I get into start menu without having access to Windows GUI?
@Andre: can you open up task manager through ctrl+alt+delete? if so, you can troubleshoot from there. If you can’t even get past logon, boot to cmd prompt + safe mode or boot from the windows disk and repair in that command prompt.
@Posters complaining about lack of admin access: Windows 7 does not natively start up command prompt in admin mode no matter what account you are logged into. Another way to open command prompt in admin mode is:
1: hit the windows key/start button
2: type cmd into the search bar
3: right click cmd icon above once found and then click “run as administrator”.
This will give the console admin rights and you should no longer get your error.
@Neggy download a fresh install of the service pack, disable all antivirus and malware protection then try again. If that doesn’t work, you may need to use a 3rd party update tool. The one I’ve used for this is advanced system care free. While that’s the only other way I’ve found to get failed updates to install properly, it should be noted that the program can flag some valid programs as bad, i.e. IBM’s Client Access Express, at least an old version.
You used to have to type in /purgecache before running this tool in winxp, possibly vista. This can be a good built in tool to run before you take your PC to the shop.
i have a problem with starting any file, they all have the same autoplay, how i returne them to their normal running???
Hi
I lose all icons taskbar and start menu within seconds of starting
file associations are all messed up in the registry
tried going back to a restore point but doesnt have any effect
help
many thnx in advance LES
I did a system restore because my wireless printer(HP 6500Aplus) stopped working, I believe it may have been after maintenance with Advanced System Care 4 Pro. During recovery, a window from Stopzilla malware protection popped up and did something to the recovery process. When I rebooted, my customized desktop was gone and replaced with the WIN logo. All the icons are on the desktop but an owner installed program does not open anymore,the weather channel doesn’t load, icons cannot be fixed to the task bar and some functions in Word 2007 don’t work. I got the printer working again by using the product CD but it does not show up in”devices and printers” nor does the printer menu icon appear on the desktop.
I did an other restore to no avail, everything is still the same.
I’d appreciate any advice about what can be done short of uninstalling and reinstalling WIN7 which is what the local repair shop recommended, thanks.
when i double click on my computer in win7 then my back and forward arrow disable.
Does anybody have some advice what to do about my WIN7 woes I explained on Nov. 6?
