Symantec Endpoint Protection will not install because it says Pending system changes that require a reboot have been detected

Delete the key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\PendingFileRenameOperations

You may also need to check for the key at these locations:
HKEY_LOCAL_MACHINE\SYSTEM\ControlSetXXX\Control\SessionManager\PendingFileRenameOperations
Where XXX is a number. Again, delete the PendingFileRenameOperations.

Do not reboot, just try the install again.

Disconnect VPN hangs

I started noticing problems disconnecting a VPN connection on my Vista SP1 machine. When I choose to disconnect, the disconnecting dialog would not go away. Trying to end task did not work. The system would hang when trying to shutdown. Something clearly had gone wrong with this...

It appears the problem is related to Symantec Endpoint Protection. I had SEP MR2 installed when I noticed this problem. After doing a little reading I confirmed others are having this same problem. It seems the problem is not limited to Vista. I saw reports of users with XP having issues.

Uninstalling SEP resolves the disconnecting VPN problem. So far I am not really liking the new Symantec Endpoint Protection. I am switching over to NOD32.
