Use the System File Checker tool to repair missing or corrupted system files

System File Checker is a utility in Windows that allows users to scan for corruptions in Windows system files and restore corrupted files. This article describes how to run the System File Checker tool (SFC.exe) to scan your system files and to repair missing or corrupted system files. If a Windows Resource Protection (WRP) file is missing or is corrupted, Windows may not behave as expected. For example, some Windows functions may not work, or Windows may crash.

Run the System File Checker tool (SFC.exe)

To do this, follow these steps:

1. Open an elevated command prompt. To do this, do the following as your appropriate:
   Windows 8.1 or Windows 8
   Swipe in from the right edge of the screen, and then tap Search. Or, if you are using a mouse, point to the lower-right corner of the screen, and then click Search. Type Command Prompt in the Search box, right-click Command Prompt, and then click Run as administrator. If you are prompted for an administrator password or for a confirmation, type the password, or click Allow.
   
   Windows 10, Windows 7, or Windows Vista
   To do this, click Start, type Command Prompt or cmd in the Search box, right-click Command Prompt, and then click Run as administrator. If you are prompted for an administrator password or for a confirmation, type the password, or click Allow.
   
2. At the command prompt, type the following command, and then press ENTER:
   sfc /scannow
   
   
   The sfc /scannow command will scan all protected system files, and replace corrupted files with a cached copy that is located in a compressed folder at %WinDir%\System32\dllcache.
   The %WinDir% placeholder represents the Windows operating system folder. For example, C:\Windows.
   
   Note Do not close this Command Prompt window until the verification is 100% complete. The scan results will be shown after this process is finished.
3. After the process is finished, you may receive one of the following messages:
   • Windows Resource Protection did not find any integrity violations.
     
     This means that you do not have any missing or corrupted system files.
   • Windows Resource Protection could not perform the requested operation.
     
     To resolve this problem, perform the System File Checker scan in safe mode, and make sure that the PendingDeletes and PendingRenames folders exist under %WinDir%\WinSxS\Temp.
   • Windows Resource Protection found corrupt files and successfully repaired them. Details are included in the CBS.Log %WinDir%\Logs\CBS\CBS.log.
     
     To view the detail information about the system file scan and restoration, go to How to view details of the System File Checker process.
   • Windows Resource Protection found corrupt files but was unable to fix some of them. Details are included in the CBS.Log %WinDir%\Logs\CBS\CBS.log.
     
     To repair the corrupted files manually, view details of the System File Checker process to find the corrupted file, and then manually replace the corrupted file with a known good copy of the file.

How to view details of the System File Checker process

To view the details that included in the CBS.Log file, you can copy the information to the Sfcdetails.txt file by using the Findstr command, and then view the details in the Sfcdetails.txt. To do this, follow these steps:

1. Open an elevated command prompt as described in the previous step 1.
2. At the command prompt, type the following command, and then press ENTER:

   findstr /c:"[SR]" %windir%\Logs\CBS\CBS.log >"%userprofile%\Desktop\sfcdetails.txt"

   Note The Sfcdetails.txt file contains details from every time that the System File Checker tool has been run on the computer. The file includes information about files that were not repaired by the System File Checker tool. Verify the date and time entries to determine the problem files that were found the last time that you ran the System File Checker tool.
3. Open the Sfcdetails.txt file from your desktop.
4. The Sfcdetails.txt file uses the following format:
   Date/Time SFC detail
   The following sample log file contains an entry for a file that could not be repaired:

   2007-01-12 12:10:42, Info                  CSI    00000008 [SR] Cannot 
   repair member file [l:34{17}]"Accessibility.dll" of Accessibility, Version = 
   6.0.6000.16386, pA = PROCESSOR_ARCHITECTURE_MSIL (8), Culture neutral, 
   VersionScope neutral, PublicKeyToken = {l:8 b:b03f5f7f11d50a3a}, Type 
   neutral, TypeName neutral, PublicKey neutral in the store, file is missing
   

How to manually replace a corrupted system file with a known good copy of the file

After you determine which system file was corrupted and could not be repaired through the detail information in the Sfcdetails.txt file, find where the corrupted file located, and then manually replace the corrupted file with a known good copy of the file. To do this, follow these steps:

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. You may perform a System File Checker process on that computer to make sure the system file that you intend to copy is a good copy.

1. Take administrative ownership of the corrupted system file. To do this, at an elevated command prompt, copy and then paste (or type) the following command, and then press ENTER:
   takeown /f Path_And_File_Name
   Note The Path_And_File_Name placeholder represents the path and the file name of the corrupted file. For example, type takeown /f C:\windows\system32\jscript.dll.
2. Grant administrators full access to the corrupted system file. To do this, copy and paste (or type) the following command, and then press ENTER:
   icacls Path_And_File_Name /GRANT ADMINISTRATORS:F
   Note The Path_And_File_Name placeholder represents the path and the file name of the corrupted file. For example, type icacls C:\windows\system32\jscript.dll /grant administrators:F.
3. Replace the corrupted system file with a known good copy of the file. To do this, copy and paste (or type) the following command, and then press ENTER:
   Copy Source_File Destination
   Note The Source_File placeholder represents the path and file name of the known good copy of the file on your computer, and the Destination placeholder represents the path and file name of the corrupted file. For example, type copy E:\temp\jscript.dll C:\windows\system32\jscript.dll.

Hidden truth about facebook

Facebook as the name suggest its one of the best social media currently know to every teenage as well as old hags all around the world.

There are some facts about facebook that they won't tell us.

Did you know.....
You can only send friends request upto 857. And if you try to add more they will show a message you have extended you limits and bla bla stuff.

You can you add friends 5000 not more then that. If you have pending request to confirm they won't be able to add you only follow you.

If without you knowledge someone blocks you  or deactivated their account it will still be counted in your friends list unless you search manually and unfriend them one by one.
Note- there is no way to find who has blocked you or deactivated their account. Facebook does not provide any special option.

If you want to add some and don't know if its a male or female. Just go to about option of that profile and it will show you by saying "where he lives" or "where she lives". And if the person clames to be a girl but shows where "he" lives then immadiately unfriend them. It will save you space and make room for others.

You can also search people by using their phone numbers and email address. But some times it does not work.

If you are looking for sex chat then just do a google search and see which country has the highest sex ratio and according to that search for people who are from that country. Add them who has add friend button and go threw their friend list for hot chick. And later u can unfriend the old hags. And keep in mind when you add a person try to chat with them. If they don't reply to your message just dont waste time unfriend them.
Note- facebook gives use 5000 rooms for friends. But this earth is with million of hot chicks. Don't waste time on one. There are other cuties in the line.
