Task manager won't launch after windows update

[ElAguila]

I am running Windows 7 Home Premium x64. I got a notification telling me that were updates available. After doing these 15 updates(some were for office and some for windows) I let it restart my computer. After the system booted back up and I logged in, I could no longer get the task manager to launch. I tried it from a shortcut I have, from right clicking on the start bar and from using the ctl alt del method. It would not launch. I got no message or anything. It would not work on any of my logins. The only way to get it working again was to perform a system restore to before the updates. I have attached a jpg which lists the updates that I said yes to. Any ideas what might be happening. I use NIS 2011 for security suite and haven't had this issue before. I have scanned my system with NIS and Spybot Search and Destroy and found nothing wrong.

You can add this reg file:

Enable Task_Manager.reg

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System]
"DisableTaskMgr"=dword:00000000
