yes its possible....but um its surrounded with boot up files, so that means if you mess up and try and alter the wrong file you just ruined ur computer, and i dont kno of any way to fix it, so i recommend not doin it.
Yes, agreed. If it says Home edition or Professional when you boot up, it's not sp2. When it says nothing and the dots are blue, yeah, sp2. A way to change the boot screen is here: http://www.tgtsoft.com/prod_sxp.php
Well, that's REALLY weird. How old is your comp? Those dots are supposed to be blue... huh... done any regedit lately? Was that from everest? Or what? Press windows + E and then right click any where on the white space and tell me what it says...
