Please use the code tag next time (# on the toolbar). Meanwhile, I think the problem is solved
Tracking down the changes
Ok, now you have to search for ini, then you'll come up with
Figuring out the correct key
HKU\S-1-5-21-2067588949-2235887507-1292767714-1001\Software\Classes\inifile\DefaultIcon\: "C:\Users\Admin\AVSIC ICONS\DI FILE INI 1.ico,0"
Because of the way the registry hives are mapped, you have two options:
1. Change default system values in
2. Change current user values in
Keep in mind that when user associates a file type with a program, the program icon is used. So what you're actually doing here is changing pre-defined icons for all users.
If you change the icon path under either of these keys, you'll get what you want depending on your goal. This comes from the KB articles I linked to:
HKEY_CLASSES_ROOT is a subkey of HKEY_LOCAL_MACHINE\Software.
To change the settings for the interactive user, changes must be made under HKEY_CURRENT_USER\Software\Classes instead of under HKEY_CLASSES_ROOT.
To change the default settings, changes must be made under HKEY_LOCAL_MACHINE\Software\Classes.
If you write keys to a key under HKEY_CLASSES_ROOT, the system stores the information under HKEY_LOCAL_MACHINE\Software\Classes. If you write values to a key under HKEY_CLASSES_ROOT, and the key already exists under HKEY_CURRENT_USER\Software\Classes, the system will store the information there instead of under HKEY_LOCAL_MACHINE\Software\Classes.
Using the correct folder for icons
Keeping icons in your profile is not a good idea, unless you'll be the only user, and especially if you plan to use it on several PC. Create a folder FileTypeIcons in the root of Windows folder.
Using the correct parameter type
Now, this is the REG_EXPAND_SZ parameter type, because it ensures that environment variables get expanded properly. It will be tricky to change the exported REG-file by analogy (export the key above and see what I mean). Using REG_SZ will work, but it's better to keep it expandable with a CMD-file.
Putting the command together
The elevated reg add /? command will provide you with the help and examples you need to test your first change. I'll leave the exact command for you as an exercise Note that you may need to restart explorer or reboot for the changes to take effect, since they occur in HKLM.
