How do I change files in ROM?

[darrakk]

I have searched everywhere, and all I can find is instructions on how to flash a new ROM. I don't want to flash a new ROM, I just want to remove a few files from my Windows directory. Everytime I try, it tells me "Access Denied" and gives me a message that the file is in ROM. Being as ROM is read only, I assume I have to unlock it somehow to change files in there?

Also, how do I search for things in this forum? I tried "Change files in ROM HTC Vogue" and got the following. How many words is 3?
