اینم یه سورس دیگه برای غیر فعال کردن و فعال کردن task manager

Enable/Disable Task Manager using VBScript

کد:

Set shell = CreateObject("Wscript.shell")

X=Inputbox("Enter choice, 1 to disable, 0 to enable")

If X=1 Then
Shell.RegWrite "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System\DisableTaskMgr", 1, "REG_DWORD"
Else
Shell.RegWrite "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System\DisableTaskMgr", 0, "REG_DWORD"
End If
