No matter how you mod the bootres.dll it will require a digital signature and that disappears as soon as you mod it.. If there is no digital signature then it will just show the old vista bootscreen.. so just give up.
Which would be the wise thing to do.
I allready said that I'd strongly advise against it. It's a security hole.

if it is a security hole it was done deliberately by microsour to keep people from modding. i am so sick and tired of microsour trying to force everyones pc to look the same. as for impossible, nothing is impossible. someone will get around microsours bulls##t.

That means these words are not in the picture. So where are they from? Where is the file and the script where it says to show these words at the boot logo/screen and how to get rid off them?

I think I may have found where the "Starting Windows" for your boot logo is located. Give me a day or two to test a couple things and I will post instructions on how to change it....

How far are you?
Can it be done?
And for those here writing stuff totally off topic, please write that stuff somewhere else. Here we are trying to change/modify the bootscreen! Let the hackers do what they do best and help us noobs out.
In regards to "it cant be done because of a digital signature", can't that signature just be copied and replaced to the bootres.dll file after it being modified as we want it to be? (sorry for not knowing much about digital signatures and stuff...I'm a noob )

That's exactly why m$ put in the signature. To prevent ppl from making changes. BUT like I mentioned, with very good reason. It's actually one of the few things m$ really thought about and did right. It's a hacker's delight to gain access to your accounts.

I think it's rather GOOD to talk about stuff related to this bootscreen issue. Ppl really need to be aware of the possible consequences of changing that screen.

And as for the signature, duplicating and implementing it in another bmp is possible, but not quite that easy to do, so the question here is is it really worth the hassle ?

Hell yea it's worth! I want my grinning eyepatched skull back with the text saying: Micro$hit Windows Pirated Edition, Right to copy

Bythe way,I never had a single virus with XP ('cept for blaster mybe ) and i used a TON of bootscreens (which were freakin' exe's! Dont tell me, THOSE weren't security risks!)

From m$ :

"The reasons for this should be pretty clear, which is that we cannot guarantee the security of the system to allow for arbitrary elements to be loaded into memory at boot time. In the early stages of starting Windows, the system needs to be locked down and execute along a very carefully monitored and known state, as tools such as firewalls and anti-virus checking are not yet available to secure the system. And, of course, even though we’re sure everyone would follow the requirements around image size, content, etc. due to performance, we would not want to build in all the code necessary to guarantee that all third parties would be doing so,"

In my opinion it is pretty valid and understandeable standpoint, from a devolloper's perspective. Your memory will be exposed during time of the bootscreen when unsigned, hence the lockdown by the means of a digital signature.

I fully understand your (and the devs') point, yet I think we are willing to take the risk. Customizing your OS always comes with risks, and it is our own decision whether we do it or not.
By the way, MS, by making this operation difficult just made it less likely that virus-writers would use it. See, changing XP's bootscreen was a piece of cake, yet I never heard of anything exploiting that. I'm not in worry about this issue.

The "Starting Windows" text is located in winload.exe.....however, as people have said, both bootres.dll and winload.exe are protected by digital signatures.....

I have figured out how to export the digital signature from the original files, however.....Unfortunately I haven't found a program that will convert the exported signature file into a useable format so that the modified files can be signed with it....

in a nut shell it is a bootscreen it has no need to be tied to the boot processes. from vista on down you always had the option in the past of changing it or bypassing it altogether without messing up the system security. the only reason ms has it setup this way is so they always get their free advertising during every bootup.

it is an image. now if someone is stupid enough not to scan the image for spyware, viruses, trojans, keyloggers, or rootkits before they use it as bootscreen then they get what they ask for. treating every user like they do not know what they are doing i a great way to loose customers.
