I second that... That could really mess with my brothers head! HAHA
not a good idea... keeping your pc plain and simple... is safer... dont fancy your pc too much... imo...
I asked for windows Boot screen not for logon screen...!!
I would not recommend playing around with registry to change boot skin because I once did that and my system was screwed. I had to format the drive.
Using Third party application is only thing that I can recommend.
Why would you want to change it in the first place??? Messing with the registry is not safe unless you know what you are doing or unless you have a backup.
i used tuneup utilities to change mine,including the start logo
