Try going to safe mode if u get run there. Otherwise try safe mode, command prompt.
Open registry editor and edit the following
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer]
Value Name: NoRun
Data Type: REG_DWORD
Revert back with results.
Data0 = disabled, 1 = enabled)
I tried the regedit and still nothing, i have tried in safe mode and i still cant get it. Also in task manager the "New Task" box is greyed out and i cant click on it!!
