Here's my experience thus far gaining access over my school's computer (stupid computer applications class d'oh)
At my school the Internet Explorer's "Save" is blocked but I installed Firefox by choosing "Run" instead of "Save."
I didn't install to Program Files which I apparently do not have access to.
To access Windows Explorer, I double-clicked the "Programs" from the Start Menu.
Then I google'd GPass and download some
older version off some other unblocked site because the official GPass site is blocked.
I updated GPass.
Status: School Firewall bypass & I have Firefox
.
Then I started to play around. Command prompt was blocked (Even through a BAT file). So was Run (Windows + R). A lot of folders like WINDOWS was hidden not allowing me to even get to regedit.exe.
I downloaded xplorer² Lite. I could now access the WINDOWS folder (as well as the Recycle Bin to erase traces of files that I had hastily normally deleted instead of with "Shift+Delete")
regedit.exe was still blocked ("Registry Editing has been disabled by your administrator")
I also tried to get a working command prompt by downloading
Console but that did not work either ("The command prompt has been disabled by your administrator")
I downloaded Registry Workshop (but haven't had a chance to try it out yet - I assume it'll work because CCleaner was able to scan for registry errors and fix them up meaning other applications have Registry key read/delete access...we'll see about write access)
If Registry Workshop works I'll do the following:
[HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\System]
I'll edit the DisableCMD and DisableRegistryTools keys' values to 0
Then I'll use my new found powers to see if I can't gain admin privileges...somehow
