If you know how to make a VBS (if you don't... I'll bother telling you how later), this is a script I use if any computer gives me the "Cmd prompt has been disabled by your administrator. Press any key to continue"
Code:
Set Shell = CreateObject("Vscript.shell")
Shell.RegDelete "HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\Systeam\DisableCMD"
Have fun! Unfortunately VBS is disabled on some computers, but I have heard, NOT TRIED, that some VBS compilers may go around this problem (VBS => EXE). Remember I haven't tried this so... if it doesn't work I'm sorry.
*NOTE: If this is considered illegal or inappropriate in any way by a mod or admin, I mean no harm. Just delete my post and give me a warning, I see how this could be considered "bad". Once again, I mean you no harm.*
