After you replace these files, you may receive the following error message after you restart the computer:
Stop 0xC000021A (Fatal System Error) The Windows Logon Process system process terminated unexpectedly with a state of 0x00000080 (0x00000000, 0x00000000). The system has been shut down.
This problem occurs because the Security Rollup Package (SRP) hotfix (Q299444i.exe) does not update the CRC values in the %SystemRoot%\Repair\Setup.log file for the files that are installed. The files that are installed by the SRP must remain on the computer after you run the repair process so that you can log on to the computer.
To resolve this problem, run Q307866.exe and then run Srpfixup.exe. When you run Srpfixup.exe, the current CRC values are verified for files that are necessary to start and log on to the computer. After the values are determined, the %SystemRoot%\Repair\Setup.log file is updated. This prevents the required files from being overwritten the next time that you run a repair process and select the Verify Windows NT System Files option.
Note This patch must be applied after you install SRP and before you try to run a repair process.

If the boot partition is using the NTFS file system, you can use this workaround if you install a parallel installation of Windows NT on a separate partition or drive, or by moving the disk to another computer to access these folders. If you cannot do this, you can use the procedure that is described in the following Microsoft Knowledge Base article to make repairs:
164471 Replacing system files using a modified Emergency Repair Disk
After you use these steps and log on to the computer, you must reapply SP6A, the SRP, and this hotfix to update the %SystemRoot%\Repair\Setup.log file. After the Setup.log file is repaired, update your Emergency Repair Disk (ERD) by using the Rdisk.exe utility.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
