Dangerous Bug in HijackThis 1.97.7 Restoral Procedure

VERY IMPORTANT. YOU MUST READ! Dangerous bug in HijackThis version 1.97.7 when restoring UserInit backups.

Warning, there is a dangerous bug in the restoral procedure for restoring keys to UserInit. If you using HijackThis to fix a incorrect UserInit setting, and then in the future want to restore that key from a backup, it will overwrite the values for the wrong key on restoral.

This was tested numerous times on numerous computers and it will changes the wrong key, and leaves the actual UserInit key alone.

Detailed Information:

If the key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon:UserInit contains extra programs other than userinit.exe, it will list that error in the F2 section on a scan.

When you fix this error it will make a backup of that key.  If you restore that key, it should go back and replace the key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon:UserInit with the information in the backup.

Instead, it adds that information to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon:Shell, and replaces explorer.exe with the information found in the backup.
Needless to say doing a reboot after restoring that key, would not be pleasant.

Just be careful when advising people to restore entries from that Key. I will notify the other message boards and have already notified Merjin.
