REG:win.ini: load= | run=

Here is some info on the F2 & F3 entries:
Quote:

F2 and F3 entries correspond to the equivalent locations as F0 and F1, but they are instead stored in the registry for Windows versions XP, 2000, and NT. These versions of Windows do not generally use the system.ini and win.ini files. Instead of backwards compatibility they use a function called IniFileMapping. IniFileMapping, puts a all the contents of a an .ini file in the registry, with keys for each line found in the .ini key stored there. Then when you run a program that normally reads their settings from an .ini file, it will first check the registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\IniFileMapping for an .ini mapping, and if found will read the settings from there instead. You can see that this key is referring to the registry as it will contain REG and then the .ini file which IniFileMapping is referring to.

They can be 'fixed' with HJT as the ones you'r pointing to do not designate a file.
