SFC Scannow - How to Use SFC Scannow to Repair Protected Windows

Scannow SFC

Windows XP has the ability to protect itself from system instability caused by 3rd party software

overwriting important system files.
This used to be (and still is in fact), a problem with Windows 95 and Windows 98.

With the introduction of Windows Millennium Edition, Microsoft made a real effort to stop this from happening.
Now in Windows XP we have a much more refined protection of these important files...

Windows File Protection

By default, Windows File Protection is always enabled and allows Windows
digitally signed files to replace existing files safely. Currently, signed files are distributed
through:

# Windows Service Packs

# Hotfix distributions

# Operating system upgrades

# Windows Updates

# Windows Device Manager


If you introduce a file replacement in any other way, Windows File protection will overwrite your file!

How to use Scannow sfc...
The main reason for using this utility is when you suspect there may be a problem with a Windows XP system file.

Perhaps you get a dialog box appear informing you of a problem with a .dll file, or your program will just not load! It is therefore worth checking to see if there are any corrupt system files using scannow sfc.

To do this simply go to the Run box on the Start Menu and type in:

sfc /scannow

This command will immediately initiate the Windows File Protection service to scan all protected files and verify their integrity, replacing any files with which it finds a problem.

The following should appear to give an indication of how long the process is taking.

 

n an ideal world that would be the end of the story... Any corrupt, missing or incorrect files would be replaced by this process.
