Issues fixing corrupted files in Windows Vista

[cokanero]

I have Vista Home Premium installed on my laptop.
I opened Elevated Command Prompt, and ran sfc /scannow to check integrity of my system files and I got following outcome in my Comand prompt window:
***********************************************************

C:\Windows\system32>sfc /scannow

Beginning system scan. This process will take some time.

Beginning verification phase of system scan.
Verification 100% complete.
Windows Resource Protection found corrupt files but was unable to fix some of th
em.
Details are included in the CBS.Log windir\Logs\CBS\CBS.log. For example
C:\Windows\Logs\CBS\CBS.log
***********************************************************
Then I verified my CBS.log file and found out that there were many lines indicating:

************************************************************
Can anyone let me know what SystemRoot\Winsxs\Temp\PendingRenames directory stands for and why all these files were moved to SystemRoot\WinSxS\FileMaps directory?
I attached my CBS.log file and is it possible that someone takes a look at [SR] entries in order find out why sfc commant detected corrupted files?

I searched this log file for Corrupted keyword and couldn't find any entries in it.
Should I still be concerned?
Is there a directory that holds snapshots of intact system files that could be used to replace corrupted ones?
Any reply would be highly appreciated. Thank you.

I will better recommend you to use Vista Repair option. If you are in this case, try Vista Repair from the installation DVD . The option to try first is the System Restore. Before attempting a repair, consider using System Restore . This feature allows you to fix most bugs. This is the most easiest way and better way instead of dealing with most of the fix.
