If you don't leave a space, the line of code will have 'null value' and be discarded from the script, causing possible problems. The space is important- it fools Vista into thinking there is some text to display, when that text is actually a blank space. Anyways, if you really want to remove the branding, open win32k.sys with a resource editor, go down to the 'Message Table' folder, open resource 1033 under folder 1, and delete the text in quotes on lines 210-215, plus line 219, making sure you leave a blank space where each line of text was (ex: replace'Vista (TM) Beta 1' with ' '). I warn you, you need to be very careful- this is an important system file! I may post my hacked copy later, but not until I'm sure it won't mess up someone else's computer. That file is 'win32k.sys', located in your 'system32' folder.
If you want to remove the 'watermark' branding from the bottom right corner of Vista that appears on your desktop, you have to hack the system file that controls it.
