How you can enable the hidden boot screen in Windows Vista
(Repost nam sry)
Now..Here's the default boot screen
And here's the hidden one, called "Aurora"
For enabling it,all you have to do is type msconfig into the start menu search box, and hit enter.
Now navigate to boot tab,and then check the "No GUI boot"
checkbox.
Hit OK and reboot the computer. You should see the new boot screen immediately on restart.
Note:
You may get a Windows Defender error on the next startup. You can 1)enable the system config utility using the tray icon and this error will go away.
2)I'am Test this.But Second time I can't access this.But One time surely

you can do this and if u dont like Aurora you Can remove.
so, I changed to old one
