I have been back and forth installing and uninstalling these two updates since 8/16/15. I’ve installed them together and individually, uninstalling them each time. They both exhibit the same behavior.
After installing and rebooting I cannot start any program successfully. I’ll wait for the boot activity to settle down and try to start a program – any program. The program will show momentarily in the task list, but then disappear. No window ever opens unless the program is IE. I can start the Control Panel after a while. I notice in the task list that trustedinstaller.exe is running and consuming a large amount of memory – over 100MB.
After uninstalling the update (or both if they are both installed) things return to normal.
I don’t know where to go after this. I’ve searched and found others with similar trouble, but no solutions. So I have two questions. Are these really necessary for a win7 machine? If they should be installed, how should I progress?
Thanks!
