There was an update, October 2015, to my Windows 8.1 desktop that runs Landesk Management console 9.6sp2. After restarting, a Windows error popped up when I tried to open the management console. It stated some nonsense about not being able to open the file due to a variety of issues, including not having permissions.
This is a workstation hooked to a domain and I was logged on as an account with Admin permissions due to a group on the domain that gave such rights.
I checked the file permissions of the Managemenet Console file and the permissions for the domain were still in place.
I checked the updates that were installed, and some were fixing account security issues. Any windows update affecting those types of security issues cannot be uninstalled.
I tried to manually install the one update that the computer needed and looked like would fix the problem, but it wouldn't install, probably because I didn't really have any rights.
I was able to open the Start button link of "Command Prompt", but not "Command Prompt (Admin)", and I was always able to open both before.
