This error message can happen if the file is corrupt or missing. To resolve this problem, you can reinstall the operating system and restore the registry files from a backup. The registry files may have been corrupted because of hard disk corruption or some other hardware problem. To resolve this issue follows the steps given below:
1. Start your computer by running the Recovery Console, run the chkdsk /p command on the drive, and then restart your computer. Test to determine whether the issue is resolved. If the issue is resolved, do not complete the remaining steps. If the issue is not resolved, go to step 2.
2. When Windows loads, press SPACE BAR when the "Load Last Known Good" message appears.
3. Complete a parallel installation, and restore the registry files from a tape backup. To do so:
o Reinstall Windows in a separate folder.
o Restore the damaged registry hive from backup. This procedure is specific to the backup application that you used to make a backup. Consult the documentation of your backup application or consult the vendor if you need assistance. Typically, this procedure requires you to restore a system state backup to an alternate location, and then copy the appropriate registry files to the %SYSTEMROOT%\System32\config folder of the damaged operating system.
o If you do not have a tape backup, include the backup of network servers and production workstations.
NOTE: If Windows is stored on a FAT partition, you can restore the files by using another computer and by copying the registry hive files to the %SYSTEMROOT%\System32\Config subfolder.
