If you happen to notice in a fully patched Vista machine in Task Manager, the process, taskeng.exe appearing loads of times. Don’t worry. This has beem bugging me for ages and finally found a fix.
Right Click on the “Computer” icon on your desktop and pick “MANAGE”
Expand the “Task Scheduler” bit on the left
Click on Task Scheduler Library
Click o the View menu top of the window and select “Show Hidden Tasks”
One will be called USER_FEED_SYNCRONIZATION-{…………} That is the culprit. Right click on it and select disable.
Reboot (easier than trying to kill the processes)
Keep an eye on it.
