Windows 7 Repair

[Samoyed]

Hi,

 

I'm running a well used version of Win 7-64 SP1.

 

I ran the sfc /scannow command and was told there are corrupted files that the system cannot repair.

 

As I built the PC myself from components I have the original Windows 7 OEM disk.  I was told I can run setup / install from that and select the "Upgrade" feature and the system will replace the windows OS files with the latest versions and (hopefully) uncorrupted.

 

According to what I've read I will not loose anything on the system, all my apps, files, wtc will still be there, the only difference is the system will work better with the uncorrupted files replacing the bad ones.

 

Has anyone actually doine this proceedure and does it work that well?  Is there anything special I need to do?

 

I'm assuming boot the computer from the CD drive witht the original OEM system disk in place.  But is that it?

 

Thank You.

whenever sfc scannow tosses up errors for me, i do what this describes:

and it seems to work quite well for me.

 

for those too lazy to click

sfc /scannow

 

Dism /Online /Cleanup-Image /RestoreHealth

sfc /scannow doesn't actually do anything. And the files probably aren't even corrupted.

 

You could try to use DISM to "repair" the files from an ISO/mounted version of windows:

 

Dism /Online /Cleanup-Image /RestoreHealth /Source:c:\test\mount\windows /LimitAccess

When I tried running Dism /Online /Cleanup-Image /RestoreHealth

I got the following error:

 

Microsoft Windows [Version 6.1.7601]

Error: 87

The restorehealth option is not recognized in this context.
For more information, refer to the help.

The DISM log file can be found at C:\Windows\Logs\DISM\dism.log

 

What did I do wrong?

So I take it no one on here has had to try to repair Windows 7 using the setup / upgrade meathod?
