Windows 7: Sfc scannow error

Today i tried sfc /scannow by running cmd prompt in administrator mode but after 15% of scanning it showed some error.I've uploaded the screenshot.Help me..

Time for a repair install from the win 7 dvd.

Here is the Tuorial. Repair Install

Did you log in using the super admin account for Windows 7? SFC requires a high user level to be able to use SFC and other high level commands.

After trying the super admin approach, if it does not work I suggest restoring the last known good backup image of your system. Otherwise you will have to re-install the OS.

I hope you make backups on an external drive!!!


To Make A Super Admin Account

1) click Start
2) in the search pane type cmd and run
3) type net user Administrator /active:yes
4) restart your computer
5) once the welcome screen loads, the Administrator account will be available for access alongside other user accountsthe first thing you should do is create a password, then go ahead and install all the drivers and programs you want.

To hide the admin account again, just repeat steps 1 thru 4, except on step 3 alter/active:yes to/active:no. once you restart your computer the admin account will not be on the welcome screen.

You can run sfc several times with rebooting after each run to see if things get better - i.e. less errors and more % checked.

Usually after the third run if there are still problems reinstallation can be considered.

one question on the repair install , if I have all my user files on a different drive then c , will this screw up the repair install . wondering .. ???

Repair install doesnt touch user files, just OS files.

but --

To upgrade Windows, the Users, Program Files, and Windows directories need to be on the same partition. Upgrading when these directories are not on the same partition is not supported. Moving these directories so that they are on the same partition is also not supported. You can choose to install a new copy of Windows 7 Professional instead, but this is different from an upgrade, and does not keep your files, settings, and programs. You’ll need to reinstall any programs using the original installation discs or files. To save your files before installing Windows, back them up to an external location such as a CD, DVD, or external hard drive. To install a new copy of Windows 7 Professional, click the Back button in the upper left-hand corner, and select “Custom (advanced)”.

Repair install does not equal "upgrade". Just to be sure I would backup, and create a restore point.

in the tutorial it tells you to pick upgrade , I do not see anywhere where you can select repair ..
