everytime i download a bootskin i get it in the file NTOSKRNL.EXE but when i go 2 open it it says application cannot be run in win32 mode can someone help me plzzzzzzz????????

The NTOSKRNL.EXE file isn't a file that you run to install the boot screen... it is the boot screen. You need to replace the file that's in your Windows directory (I can't remember where it is) with this one.

Just a warning: if you don't have the right NTOSKRNL.EXE file, then you'll end up with a computer that won't boot! A much better option is to use BootSkin by StarDock. If anything goes wrong, you can still get into Safe Mode and turn off the Boot Skin.
