If the process fails, the result could be a completely inaccessible system that cannot boot. Such errors might compel you to reinstall Windows and hence, restore data from backup. Problems might raise if you find data backup currently invalid, to restore which, you need use a powerful Data Recoverytool.

To illustrate such scenarios, consider that you use a Windows XP-based computer system. When you start your computer, you might come across the below error code that prevents your system from starting:

“Error code: 0x80004005”

If you are unable to resolve the issue, perform uninstall of Windows XP and install the earlier operating system.

• You need to replace few Windows files if you haven't upgraded your system. To do so, start the computer using Windows XP CD and execute the following sequence of commands:

• cd C:\WINDOWS\System32

• RENFile_Name.extensionFile_Name.old (where File_Name.extension are Wpa.dbl, Actshell.htm, Pidgen.dll, Wpabaln.exe, Licdll.dll, Regwizc.dll and Licwmi.dll files and File_Name.old is the new file name)

• D: (It can be replaced with the drive letter of your CD drive)

• cd i386

• Expand File_Name.extension C:\WINDOWS\System32 (Where File_Name.extension are the file names used earlier)

• Exit

• If the problem persists, perform clean reinstallation of Windows XP
