How do I delete protected operating system files?

Ok, I'm assuming you are technically adept. So let me know if I am talking over your head:

System Key: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]
Value Name: SFCDisable
Data Type: REG_DWORD (DWORD Value)
Value Data: 0 = enabled (default), ffffff9d = disabled

That's the registry Key. Here are more values:

1 - disabled, prompt at boot to re-enable
2 - disabled at next boot only, no prompt to re-enable
4 - enabled, with popups disabled
ffffff9d - for completely disabled

So you can disable WFP, delete it and enable it again.

Note: Don't do this unless you know how to backup your registry and are comfortable with this kinda thing.

Finally someone with a method that bypasses the protection. I've been ripping my hair out every since I was left with redundant system files that refused to go. I went to forum to forum and I got ideas like, slave your hard drive, install another OS, and even back up your drive and FORMAT it, hahaha.

I'll try your method and I'll reply back with the results. Thank you.

No problem.

Question. In Current version, on the right window theres a list of names, one of them is called current version and the value is 5.1. Is that the right current version I'm supposed to modify?

Sorry, I posted an incomplete registry key. I forgot the last part.
I've edited my post to include more information.

Make sure to back up your registry so that my typos and ommissions don't take down your box. :wink:

Damn, nothing happened. I was still left with access denied error messeges.

A weird thing is, the other numbers didn't work either. I used the number 1, yet it never gave me a pop up when I restarted.

Could it be only for windows NT?

I found the solution:
You are supposed to delete them in system recovery console, but before you go into that you're supposed to change some settings in windows, heres a link:

Thanks for trying. =) I appreciate it.
