If you press CTRL+ALT+DEL, the Windows Security dialog box appears; therefore, the computer has not actually stopped responding.
This may occur if Sulfnbk.exe remains on the computer when you upgrade to Windows XP. Sulfnbk.exe is a Windows utility that is used to restore long file names. This utility is not included in Windows XP, Microsoft Windows 2000, or Microsoft Windows NT.
To resolve this behavior, follow these steps:
Sulfnbk.exe is not used by Windows XP and is not needed.
